I can not find a way to fix this problem I am having with an object that works fine in AC19 but in AC20 it is allocating a “Custom Pen” despite the object having parameters that control the pen colours.
In AC20 if you select different pens it makes no change to the object, it steadfastly shows the “Custom Pen”. I have never seen ArchiCAD allocate a custom pen before it is rather weird. Other parameters do have an effect on the object.
I have tried saving the object “as a new object” and overwritten the old version but that did not change it’s behaviour
Has anyone else had this problem or have I found a glitch in AC 20?

This also applies to Fills
ps I posted this originally on the ArchiCADTalk forum as I am uncertain which forum I am supposed to use these days for GDL object problems
