3D Mesh Tutorial

General

• 3D mesh is not a slid
• 3D mesh does not have thickness
• You can color it and add texture
• You cannot make holes
• Difficult to modify once created

In order to use EDGESURF, you need connected 4 lines. They can be any line such as Line, Polyline, Spline, and Arc.

1. Make the space using straight walls (Shown here in white and yellow)

2. Create 3 Viewports

View - Viewports - 3 Viewports, then enter
Activate and change views on each window. Plan, Front, and Isometric views.
View - 3D Views - Plan (Front, and Isometric)

3. Draw a spline for the shape of the wall
Using elevation view with OSNAP off, use Spline to draw the shape of the wall.
The red line above may not show up at the location of the wall. Move it after drafted to the location using the plan view - OSNAP off.

4. Duplicate the red line

Copy the red line for the shape of the mesh - OSNAP off. They can be just two at the ends if the wall is straight. Rotate them if necessary.

5. Draw top and bottom lines

Back to one viewport. View - Viewports - One
Use arc or spline to draw the top and bottom lines. This example shows Arc lines segments. Use OSNAP to connect the lines.

6. Connect the bottoms.

Make sure all the lines are connected using OSNAP.

7. Connect all the arc lines at the top and bottom

If you used spline to connect them all, you can skip this.

PE enter (Polyline edit)
Click on one arc
Enter
J enter (Join)
Click on all lines you wish to join
Enter

8. Increase the number of mesh
SURFTAB1 - enter - change 6 to 20 - enter
SURFTAB2 - enter - change 6 to 20 - enter
Increase the number from 6 to your choice depending on the size of wall.

9. EDGESURF

Type EDGESURF - enter - click on all 4 lines clock or counter clockwise.
You will have 20 by 20 mesh. It is smoother than 6 by 6 mesh.

If it does not work, check if the lines are connected.
