Upgrading to Cadworx 2019 and noticed the jump from steel to structure does not allow custom structure user shapes.
I am looking to see if anyone has a solution? If not, is it possilbe to create a user shape that has a variable length option (like how you drop pipe and are able to control it's length upon insertion)?
Thanks.

Structure 2019 definately has custom shapes.

Success!!!!
Update to a previous post.
(I should have posted this in structural but I was trying to tie in user shapes)

Parametric/aligned constraints/ must be added to PLINE for 2019 structure user shape.
