Extrude Edge Tool

Fills gaps between the original edges and the corresponding transformed edges with polygons. The edges are transformed using Translate, Rotate or Scale gizmo.

You can also select new edges within this tool for continuous edge extrusion.


  1. Select Extrude Edge Tool.
  2. Select several edges if there are no selected elements.
  3. Move the translation gizmo by dragging to create polygons between the first edges and the new edges.


The extruded distance.
Snap to Polygon
An edge is snapped to a closest polygon within a specific distance.
Snap to Vertex
Use 3D Cursor as Pivot
Both Sides
Creates both sided polygons.
Flips the last created polygons.

Inset Tool

This tool creates a slightly smaller or bigger polygon of the selected one.

Move the cursor over a desired polygon and start to drag a mouse. Then you’ll see that the polygon outline will be bigger or smaller. Release LMB to be done. Try to change the properties in the inspector if necessary. And press SPACE to confirm.

Multiple Inset
If several polygons are already selected when Inset Tool is activated, Inset will be applied to them at once.
Repeat the previous
SHIFT + LMB on a desired polygon repeats the previous inset.

Steps - Single Inset

  1. Select Inset Tool with no selection.
  2. Click on a polygon you want to apply Inset to.
  3. Drag the cursor to define thickness.
  4. Release LMB
  5. Adjust Thickness properties if necessary
  6. Press SPACE or start another inset action to confirm.

Steps - Multiple Inset

  1. Select Inset Tool with some polygons selected using Polygon Tool.
  2. Start to drag the mouse from a polygon or adjust Thickness property directly.
  3. If necessary, adjust Thickness property in Properties to give the precise value.
  4. Press SPACE to complete or Press ESC to cancel.


LMB Drag
Creates an inset of the selected polygon.
Duplicates the previous inset.
Confirms the current inset.
Cancels the current inset or exit Inset tool.


How smaller or bigger the polygon is. This is a distance between the starting point and the current point.
Type (for Multiple Inset)
  • Individual - Each selected face is inset on its own.
  • Group - Inset Tool operates on the region around selected faces
Bridge Edges
Links corresponding edges between the original polygon and the inset polygon.

Inset Tool Demo.

Boolean Tool

This tool creates a single game object out of two game objects by applying one of the three boolean operations.


  1. Select two game objects with UModeler component.
  2. Select Boolean tool
  3. Choose one of Union, Subtract and Intersection in the inspector.


Boolean Union
Boolean Subtract
Boolean Intersection

Boolean Tool Demo.

Mirror Tool

Mirrors a mesh along its local X,Y or Z Axes. When the mirror mode is enabled, every change will be reflected to the other side each time the mesh is modified.

Steps - Start Mirror Mode

  1. Select Mirror Tool.
  2. Adjust Axis, Distance and Invert properties to set the mirror plane.
  3. Click on Start button.

Steps - Confirm

  1. Select MirrorTool.
  2. If you want to leave a boundary between the original part and the mirrored part, check Leave Boundary property.


Plane mirror axis
Inverts the direction of the plane mirror.
The distance of the plane mirror
How to deal with the boundary edges between the edited part and the mirrored part.
  • Remove : Removes the boundary edges.
  • Remain : Remains the boundary edges.
  • Ignore : Ignores the polygons across boundary edges as mirroring is done.
Starts the mirror mode.
Finishes the mirror mode.

Loop Slice Tool

Loop Slice splits a loop of faces by inserting a new edge loop intersecting the chosen edge.


  1. Select Loop SliceTool.
  2. Move the cursor over a desired edge
  3. Scroll Wheel of the mouse to increase or decrease the number of edge loops.
  4. Drag the mouse to changes the offset of the edge loops.
  5. Release LMB to finish.


LMB Drag
Moves the edge loops.
Scroll Wheel
Increases or decreases the number of edge loop.


Split Number
The number of the edge loop.

LoopSlice Tool Demo.

Follow Tool

Extrudes a profile polygon along a path polygon. The steps to use this tool are as follows.


  1. Draw a profile polygon.
  2. Move the profile polygon near the starting point of a path polygon. Using Snap Tool will help this.
  3. Select the profile polygon.
  4. Select the path polygon.
  5. Click on Follow Tool.

Bevel Tool

The bevel tool allows you to create chamfered or rounded corners to geometry. A bevel is an effect that smooths out edges and corners.

Vertices, Edges or Polygons have to be selected before selecting BevelTool and then change the properties described below in the inspector.


  1. Select Vertex(s), edge(s) or polygon(s) with VertexTool, EdgeTool, or PolygonTool.
  2. Adjust Width, Segments or Profile value in Properties.


The width of the bevel polygon.
The number of segments. The greater the number of segments, the smoother the bevel.
The side view of the bevel edge. This is between 0 and 1. 0.5 is completely flat. Values less than 0.5 gives concave bevel and values more than 0.5 gives convex bevel.
Clamp Overlap
When selected, the bevel amount isn’t allowed to go larger than an amount that causes overlapping collisions with other geometry.

Bevel Tool Demo.

Bridge Tool

Fills space surrounded by the selected elements in following cases. The selection conditions to apply Bridge are as follows.

  • More than three vertices are selected.
  • Two unconnected edges are selected.
  • More than two connected edges are selected.
  • More than two polygons are selected.


  1. Select vertices/edges/polygons using VertexTool, EdgeTool or PolygonTool.
  2. Select Bridge tool.

Bridge Tool Demo

Clone Tool

Clones the selected polygons along the line drawn by dragging a mouse. Pressing SPACE confirms the clone action and ESC cancels it.


  1. Enter Clone tool.
  2. Point a polygon you want to clone by putting the mouse over it if polygons are not selected when this tool is activated.
  3. Drag the mouse to draw a line. You can make sure that the cloned polygons will be aligned with the line.
  4. Adjust Number, Distance and Arrangement in Properties if necessary.


LMB Drag
Draws an edge where the clones will be placed.


The number of clones
The distance of an edge where the clones will be placed.
  • Divide - Creates clones arranged evenly between the starting point and the end point of the edge.
  • Multiply - Makes clones along the edge. The distance between the clones is the value of Distance property in Properties.

Duplicate Tool (Formerly called Copy Tool)

Duplicates the selected polygons. The duplicated polygons’ center cubes will have pink color, which means that they will move separately by a gizmo.


  1. Select several polygons with Polygon Tool.
  2. Select Duplicate Tool.
