The following journal will prompt the user to select a tube feature and will report the total length of the tube. Copy and paste the following code into a text file, then save it with a name such as “Tube_Length.vb”. Create or open a file that has some tube features in it and run the journal. The tube may be made of a single sketch, multiple sketches, dumb curves, edges, or any combination thereof. The journal demonstrates how to access the individual curves used to create the tube feature, and the use of the Ui.SelectWithSingleDialog function.
