Round tubing

The Round Tubing tool and Round Tubing - 3D tool share the same position on the tool set. Click and hold the mouse on the visible tool to open the Pop-out tools list and select the desired tool.

2.Click to place the object in the drawing, and click again to set the rotation. The first time you use the tool in a file, a properties dialog box opens. Set the default parameters. The parameters can be edited later from the Object Info palette.
