Remove Group

Eraser Tool

There are two modes of deleting elements. One is Immediate Mode and the other is Edit Mode.

  • Immediate Mode - Select elements at first and then click on Eraser button to remove them.
  • Edit Mode - Select Eraser Tool first with no selected elements and then click on an edge which you want to remove.

When you try to erase an edge shared by two coplanar polygons, only the edge will be removed and the two shared polygons will be merged. Otherwise, the two polygons will be removed, too.

In a case of a vertex, all the polygons sharing the vertex will be removed. If it is a polygon, only the polygon will be taken away.

Detaches the selected polygons from the current game object to get them into the new game object.

Steps

  1. Select polygons.
  2. Select Detach button.

Detaches the selected polygons and creates a new game object, which has the detached polygons.


Combine Vertices Tool

Merges all the selected vertices in one unique one. The location of the surviving vertex can be chosen before executing this tool.

Note

If you select Combine Tool with no selected vertices, you will enter Combine Vertex mode. In this mode you can selected vertices and set up some options and combine them.
However, if you click on Combine button with some vertices selected, the combine action will happen immediately.

Interface

SPACE
Combines the selected vertices.

Properties

Select Only Visible
If on, Selects only visible vertices/edges/polygons from a camera. Occluded elements from other polygons will not be selected. This is available only when the game object has MeshCollider component.
Combine Type
  • First - Places the remaining vertex at the location of the first one selected.
  • Last - Places the remaining vertex at the location of the last one selected.
  • Center - Places the remaining vertex at the center of the selected vertices.
Collapse
It may let alive more than one vertex. In fact, you will have as many remaining vertices as you had islands of selection (i.e. groups of linked selected vertices). The remaining vertices will be positioned at the center of their respective islands.
Combine Vertices
Click on this button to combine the selected vertices.

Merges the selected vertices.


Combine Polygon Tool

Merges adjacent and coplanar polygons into a polygon by selecting several polygons and clicking on Combine button.

Combines the selected polygons.


Combine Object Tool

Combines the selected game objects with UModeler component to be an object by selecting several game objects and clicking on Combine button.

Merges the selected objects.


Remove Double Tool

Lets you merge automatically all the selected vertices within the specific distance.

Steps

  1. Select vertices, edges or polygons.
  2. Go to Remove Double Tool
  3. Adjust Distance property.

Properties

Distance
Minimum distance to be merged.

Collpase Tool

Merges each edge island or vertex island into one vertex. This makes as many remaining vertices as islands of selection. (i.e. groups of linked selected vertices).

Steps

  1. Select vertices or edges or polygons.
  2. Click on Collapse Tool button.

Cut Tool

Cuts a mesh into two along a line drawn by dragging a mouse. Pressing SPACE while dragging will change the direction of cutting.

Interface

LMB Drag
Rotates the custom plane.

Properties

Type
  • Single - Removes the polygons below the custom plane.
  • Both - Simply cuts a mesh and leaves all polygons.
Fill Facet
Fills facets with polygons.
Select Above
After cutting a mesh, selects all polygons above the custom plane.
