Steelsketch doesnt work

Im having issues with steelsketch, when I select lines and click on either create pipe or profile nothing happens… why?

There’s not much to go on in your post. Can you share an example SKP file that gives you trouble?

I just downloaded the extension now and installed it, Im now trying to just test it out by drawing some pipes with bends etc, so I started by drawing lines and then selected them after which I clicked on the create pipe icon but the pop up for setting the dimensions doesnt come up

Perhaps you should contact the author. You can get his contact info from the Extension Warehouse.

From the comments there, it doesn’t appear to support SU2016.
