Generate a 3D tube from objects

3D tab > Create group > Cone from selected line menu > Tube from selected objects, 3DTUBE2

Generate a 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-Tube dialog opens.

3. Enter the diameter of the tube.

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

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

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

7. Click OK.

The program generates 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.
