After a corridor has been built - if I see that I am missing a Corridor Feature Line because a Point in a Subassembly does not have a Point Code - can I make C3D generate the Corr. Feature Line for me in some way? I've tried adding a Code to the Subassembly Point and to the Code Set Style used by the corridor, and it appears both on the Codes tab of the Subassembly Properties and on the Codes tab of the Edit Code Set Style dialog, but I cannot make it appear on the Codes tab in Corridor Properties..I guess that is a requirement in order to have the Feature Line generated?
I usualy add a marked point to the point in question and assign the code to the marked point.
Did you click <Import Codes> and then window select your assembly, after adding your point code?
