Generate a rectangular 3D tube from a line

3D tab > Create group > Cone from selected line menu > Rectangular tube, 3DRECTUBE2

Generate a rectangular 3D tube from selected objects. A 3D tube is a structure that consists of 3D faces. If you draw the tube as individual 3D faces, the program uses the active color. If you draw the tube as a symbol, the program uses the SYMBOL color.

Do the following:

1. Select the object(s) that you want to use as the centerline for the tube. You can select lines, arcs, circles, and polylines.

2. Press Enter. The 3D-Rectangular tube dialog opens.

3. Enter the dimensions of the tube.

4. Select whether you want to remove the original lines.

5. Select the drawing line on the rectangle.

6. Select the object type. If you want to edit the individual points on the tube's surface, select Polyfacemesh.

7. If required, select the drawing accuracy of the arcs. Note that high accuracy results in a larger drawing file.

8. If required, select the arc type.

9. Click OK.

The program generates rectangular 3D tubes so that the selected lines are the centerlines for the tubes. If you selected polylines, the program generates corners between the lines. The program does not generate corners between single lines even if their end points are in the same point.
