Add menu

Edit Mode - Add Menu

In Edit Mode you will see a add menu for some object types. The number of objects that you can add in edit mode is limited to the same object type that you are in edit mode with. You can just add mesh geometry to a mesh geometry. And just curve geometry to curve geometry.

The added objects in edit mode becomes part of the current object geometry. It is one object.

Last Operator

The last operators are the same than in object mode. Please read the add menu chapter in object mode.

Add menu – Type to Search

There is also a hidden search menu where you can search for specific object types in all categories with a key press when the menu is open.

Simply expand the add menu by clicking it, and start to type in the term that you want to find – this will automatically trigger the search.

Bisect

Bisect cuts geometry along a plane. This description is a bit misleading though. You simply cut through the whole geometry by defining a line. And the cut goes through the geometry from the current view.

When you have set your cut and release the mouse then you reveal a widget with which you can move and rotate the cut. Clicking at the arrow and drag moves the cut. Clicking at the circle and drag rotates the cut.

Last Operator Bisect

Knife tool

The Knife tool cuts the geometry, and adds edges. When it crosses existing geometry then it adds a vertice at the crossing point.

Usage: activate the tool, left click to define the starting point. This can also be a point in the middle of a face. But ideally you choose an existing vertice or an edge as the start and endpoints. The knife tool tries to snap to them when you get close with the mouse cursor.

When done press Enter or Spacebar to confirm. Right click abandons the operation.

When you create a vertice in the middle of a face, then the knife tool will try to connect this vertice by an existing vertice of this face when you confirm with spacebar.

While weight painting it can happen that a vertice gets several weightings assigned. Normalize all normalizes the weight of all Vertex groups so that the values for the single vertices in the sum is 1.

Last Operator Normalize all

Subset

Subset is a drop-down menu choose the Subset method.

Lock Active

Keep the values of the active group while normalizing others.

Normalize

Normalize normalizes the weight of the current selected Vertex group so that the values for the single vertices in the sum is 1. Means when there is influence from other groups, then those values are kept, but the one for the current group gets lowered so that the sum is 1.

The Last Operator Normalize panel has no adjustable settings.

Mirror

Subset

Subset is a drop-down menu choose the Subset method.

Limit

Here you adjust how many weights are allowed.

Locks

The locks from the Vertex groups as operators.

Set Attribute

Set values of the active attribute for the selected element. It calls a popup where you can add an attribute. A vertex group index number or a uv map value for example. It depends of the element.

Sort Elements is a menu with different sorting methods. It allows you to reorder the mesh indices of the selected mesh elements by various methods.

The indices can be turned on in the Overlays menu.

View Z Axis

Sorts along the active view’s Z axis, from farthest to nearest. You can use Reverse if you want it the other way.

View Y Axis

Sorts along the active view’s Y axis, from farthest to nearest. You can use Reverse if you want it the other way.

Cursor Distance

Sorts from nearest to farthest away from the 3D cursor position.

Note that the Reverse option only reverses the order of the materials**.* And* the order of the faces inside them.

Reverse

Reverses the order of the selected elements.

Last Operator Sort Mesh Elements

Sort Elements always brings up the same last operator. But with a small difference for Randomize and Reverse. Reverse has no checkbox. And Randomize has a Seed checkbox.

Type

This is a drop-down box choose the sort method again.

Seed Edit box (Randomize only)

The seed option allows you to get another randomization – the same seed over the same mesh/set of selected elements will always give the same result!

Subdivide

Subdivide is a menu where you can quickly add and change a subdivision surface modifier with a predefined resolution in a quick way. Especially when you use the hotkey for it. The subdivision surface modifier panel can then as usual be found in the Properties editor in the Modifier tab.

Last Operator Subdivision Set

Show / Hide

The Show/Hide menu is available for all object types and in all modes. It is usually in the object related menu to find. In Object mode it's the Object menu, for a curve object in edit mode it is the Curve menu. It always contains three menu items. Show Hidden, Hide Selected and Hide Unselected.

Hide Unselected

Hides the not selected elements. The selected elements stays visible.

Last Operator Reveal Hidden / Hide Selected

Select

Define if the selected or the unselected elements gets hidden or revealed.

Cleanup

In the Cleanup menu you will find tools to clean up the current geometry.

Last Operator Delete Loose

Vertices

Delete Vertices.

Decimate Geometry

Decimate Geometry decimates the currently selected geometry. It starts with a Ratio of 1. Which means no decimation. The lower the ratio the more decimation you will get. The Decimate Modifier works with Tris!

Last Operator Decimate Geometry

Ratio

Adjust the strength of decimation.

Degenerate Dissolve

Removes zero size Faces and Edges.

Last Operator Degenerate Dissolve

Max Angle

Limit the action to a maximum angle.

Split Concave Faces

Splits concave faces to make the geometry more stable. This tool is thought for N-Gons.

Fill Holes

Fill holes closes holes in the mesh geometry.

Fill holes can just calculate one face size at one time. So when you have several holes in the mesh, let's say one is a tri, and one is a quad, then you need to calculate twice.

Last Operator Fill Holes

Sides

Define what face size will be filled.

Delete

The smart delete add-on. usually does the delete job already fine. It deletes the selected element(s).

There are sometimes some situations where you need more control over what you want to delete. The tools for this can be found in the Delete menu.

Vertices

Deletes the selected vertices, and all with it connected edges and faces.

Edges

Deletes the selected edges and the connected faces.

Faces

This one works similar to the smart delete. It deletes the selected faces.

Edge Loops

This method works similar to the smart delete tool. It deletes the edge loop. But it selects the faces of the edge ring. And the Last operator offers you the option to split off face corners.

Last Operator Delete Edge Loop

Face Split

Split off face corners to maintain surrounding geometry.

Dissolve

Dissolve operations removes for examples selected vertices, edges and faces. But they are not delete operations. They are union tools.

When you for example choose Delete vertices from the mesh menu, then the involved faces can get deleted too. When you choose Dissolve vertices, then the vertices gets removed, and the faces stays intact. The edges gets unioned.

Dissolve is a union operation.

Dissolve Vertices

Dissolve Vertices dissolves the selected Vertices.

Note that pressing Del in Vertice select mode calls Dissolve Vertices already. It's the same operator. But you don't get the Last operator that way.

Last Operator Dissolve Vertices

Mesh Select Mode

Mesh Select mode is a sub menu Set the current mesh select mode. Its functionality is equal to the mesh select mode buttons in the header. Just that you can't select more than one mode directly here.

This menu just exists to show and to edit the hotkeys. Not to work with it.

Smart Delete

Smart Delete

Smart delete deletes what is selected in an intelligent way. When you for example delete an edge then the edge gets deleted. But it also deletes the vertices connected to this edge. It performs a Dissolve operation under the hood.

There is also a Delete and Dissolve menu in the Mesh menu, choose different methods for deleting if required.

Smart delete is an add-on. And can be deactivated if desired.

UV menu

Edit Mode - UV Menu

Here you find the uv mapping methods and some further functionality. You use it best in the U Editing layout. There you can see the result in the UV Editor then.

The UV menu is just available for Mesh objects.

The Last Operator for Smart UV Project contains the same settings than the Smart UV Project Settings dialogue.

Lightmap Pack

Lightmap Pack maps each face individually, and puts the result into the UV space. Without margin.

Lightmap Pack has no Last Operator.

Settings

Follow Active Quads

Follow Active quads maps UV coordinates starting from an active face, and maps all adjacent faces in quad shape then. This way you can for example unwrap a pipe or a road. You first need to have a face selected. Then select everything. And then click at Follow Active Quads.

Settings

Project from View projects the UV from the current 3D view.

Same as Project from View, but with Scale to Bounds ticked in the Last operator. And so it scales to the bounds.

Mark Seam

The unwrap algorithms Angle based and Conformal requires to have edges marked as seams. Think of it as a cutting pattern for a trouser for example. Such a trouser is also made of fabric patterns.

Same goes for the UV patches when you use Angle based or conformal unwrapping. You need to cut your mesh into parts and mark edges as seams, so that the algorithm knows where the seams are.

Mark seam marks the currently selected edge(s) as a seam. Seam edges will be displayed as red in the 3D viewport.

Vertex Menu

Edit Mode - Vertex Menu

The Vertex menu just exists for mesh objects. It provides you with tools that are designed to modify vertices.

Legacy

The legacy sub menu contains tools that exists in the tool shelf already. It's the old way to do things. Different to the tools in the tool shelf, these tools are usually modal. And performs once. You have to call them again in case you want to repeat the tool.

Bevel

The Bevel Tool adds a bevel to the selected geometry.

Usage: first select the geometry that you want to bevel. Then activate the tool. Don't wonder that the mouse movement does nothing until you move the mouse really really far away. That's by design. Best is to adjust the amount in the Last Operator Bevel panel.

Last Operator Bevel

Affect

What geometry to bevel. Vertices or Edges.

Width type

Which measure type to choose for the bevel action. Offset, Width, Depth or Percent.

Segments

How many segments gets created.

Controls the profile shape strength. A value close to 0 bends the roundness to inside. A value towards 1 bends the curve to outside. A value of 0.5 defines a radius around the center point of the bevel.

Miter Outer

How the outer miter is set. Miter is how the bevel rounding at a corner is done.

Sharp

Creates a sharp miter.

Patch

This replaces the outside vertex of a miter with 3 vertices. And uses a patch pattern there.

Arc

This replaces the vertex of a miter with 2 vertices, joined by an arc. A separate Spread parameter says how far to move the vertices away from their original position.

Inner

How the inner miter is set. Miter is how the bevel rounding at a corner is done.

Sharp

Creates a sharp miter.

Arc

This replaces the vertex of a miter with 2 vertices, joined by an arc. A separate Spread parameter says how far to move the vertices away from their original position.

Intersection Type

Handler and node position

When you select a node, then the handler and node position tools shows below the curve window.

Rip Vertices

Rip splits the edges between the selected vertices. It creates two edges out of one.

This tool works similar to the Edge Split tool. It also selects the outer edges so that you immediately move them. Right click will snap them back to the initial space.

Last Operator Rip

Move X , Y , Z

Adjust the position.

Orientation

Orientation is a drop-down box. Choose the type of orientation for the mirroring action.

Mirror Editing

Enable mirror editing.

Proportional editing

Enables proportional editing. Activating proportional editing reveals further settings.

Proportional Falloff

Rip splits the edges between the selected vertices. It creates two edges out of one. But fills the gap.

The last operator is the same than for the rip vertices tool above.

Rip Vertices and Extend

This tool is the same tool than the Rip Edge tool from the tool shelf.

Rip Vertices and Extend extrudes out the selected vertices. When you do this operation at an edge then you will create N-Gons that way.

Last Operator Extend Vertices

Move X , Y , Z

Adjust the position.

Orientation

Orientation is a drop-down box. Choose the type of orientation for the mirroring action.

Slide Vertices

Same tool than the Vertex Slide in the Tool Shelf. Vertex Slide slides the selected vertice along the edge that it is part of. This is for the corner vertice at a cube into three possible directions.

Last Operator Vertex Slide

Smooth Vertices

Same tool than in the tool shelf. Smoothens the selected vertices.

Last Operator Smooth Vertices

Extrude to Cursor or Add

Extrude to the mouse position.

Howto: activate the tool. then right click into the workspace by holding down the ctrl key.

In the header you will see a message that the tool waits for input.

This tool has two functionalities. If the whole geometry is selected, then it creates a copy of the geometry at the mouse position, randomly rotated by a small amount. If just elements are selected, then it extrudes this element to the mouse position.

Make Edge/Face

Adds a face when you have edges selected. And Edges when you have Vertices selected. It's a Bridge tool.

You can have either the one method or the other. When you select two adjacent vertices, then you select the edge too. And the tool works in edge mode then. In this case just the possible faces gets created. Not edges between single vertices.

First select the edges or Vertices that you want to bridge. Then click the New Edge/Face from Vertices Button.

Connect Vertex Path

Connect Vertex path connects selected vertices, but takes the vertex order into account in which you selected the vertices. It just creates edges between vertices that are not connected in this order.

Connect Vertex Pair

Connect Vertex pair connects selected vertices and makes a face of the pairs.

Smooth Laplacian

Laplacian Smooth Vertex smooths out the angles between the selected vertices. It is a tool to reduce noise at the mesh. It works a bit different than the normal Smooth Vertex tool. And gives a different result. The Laplacian method allows you to preserve the volume, and to adjust border smoothing.

Last Operator Laplacian Smooth Vertex

Vertex Crease

When you use a Subdivision Surface Modifier, then you can define the sharpness of selected vertices with this tool. Crease vertices will be marked colored in edit mode.

You will see a value in the header that indicates the current strength when you activate the tool. Move with the mouse to increase or decrease the value. Or type in a value while you are in this mode. You can also scale into negative range.

A negative crease value will subtract from the current active crease value in case it exists already from a former crease operation. A Crease value of -1 removes the crease from this edge.

Last Operator Vertex Crease

Factor

Adjust the crease factor.

Blend from Shape

This tool requires to have a shape key at the mesh. It blends the selected shape key into the mesh.

Last Operator Blend from Shape

Propagate to Shapes

This tool requires to have a shape key at the mesh. It applies the current vertex locations for the selected vertices to all other shape keys at the mesh.

Vertex Groups

Vertex groups is a menu around vertex group functionality. The vertex groups can be found in the Object data tab in the Properties editor.

When there is no vertex group assigned yet then you can only see one menu item. The Assign To New Group button.

Once you have a vertex group assigned you will see the full functionality.

Set Active Group

Select a vertex group to be the active one.

Hooks

Hooks is a menu with tools around the hook modifier. You could also adjust the hook modifier from the Properties editor. But the menu items are more accessible.

When there is no hook modifier at the mesh then you just see three menu items. When there is minimum one hook modifier applied, then you will see an extended menu.

Hook to New Object

Creates a new Hook Modifier for the active object and assigns it to the selected vertices. It also creates an empty at the center of those vertices, which are hooked to it.

Hook to Selected Object

Does the same as Hook to New Object, but instead of hooking the vertices to a new empty, it hooks them to the selected object (if it exists). There should be only one selected object (besides the mesh being edited).

Last Operator Hook to Selected Object

Active Bone

Hook to the object(s) of the active bone.

Make Vertex Parent

Parents another object to the selected vertice(s).

Workflow:

In Object mode select the object that you want to parent to a vertex. Shift select the parent object so that both are selected. Enter Edit mode. Then select one vertex for a single point. Or three for an area. Then click the Make Vertex Parent button to make the relation.
