- Hover over an edge with a density of 12 and press Ctrl > C to copy its settings.
- Hover over an edge you wish to change and press Ctrl > V to paste the settings.
- If necessary, select Update from the guide bar.
Tip: From the guide bar, click and select Auto update to automatically update the mapped surface. -
Select the General 2D Mesh > Edit Faces tool from the 2D ribbon.
-
In the modeling window, select the two surfaces
highlighted in Figure 8.
- In the microdialog, set Element type to Quads only.
- Select the Map Type tab, and verify Map as is set to Rectangle.
-
From the Topology ribbon, select the Split > Interactive tool.
-
Left-click and drag to create a line to split the surface.
-
Left-click to create two fixed points.
-
From the 2D ribbon, select the General 2D Mesh > Create tool.
-
In the modeling window, select the two surfaces and
click Mesh from the guide bar or
microdialog.
-
If necessary, select the General 2D Mesh > Density tool from the 2D ribbon.
-
Set the edges density as shown in Figure 15.
-
Select the General 2D Mesh > Edit Faces tool from the 2D ribbon.
- In the modeling window, select the right part.
- In the microdialog, verify Element type is set to Quads only.

-
Set the edges density as shown in Figure 22.
Note: Your edge density may be slightly different. Adjust the edge density to obtain a regular mesh as shown in the images.
-
Select the General 2D Mesh > Edit Faces tool from the 2D ribbon.
-
In the modeling window, select the surfaces highlighted
in Figure 24.
- In the microdialog, verify Element type is set to Quads only.
