Thanks for the explanation Gergely. I do hope an alternative will be looked at. I believe in beta we could save a stair to our linked library. That was very important for me, and no doubt to many other users. I need to access my "stock" stairs easily without having to remember what pln I made a stair for to go find it. That would be ridiculous to manage. I keep over 300 plns active and alive, meaning I constantly update them with new AC advancements... ie, replace an old stair with a new one just like it, but enhanced.
At one point Stairmaker stopped allowing editing of pre-dated stairs, which I understand that need. However, now as I want to replace a standard stair, I can no longer simply browse the tool and place a stair. I need to export/import to do so, a waste of time, and a pain. I guess I will have to open those plns (which want be easy to figure out) I made stairs in under AC13, and export those to an external separate folder for importing, or cearte a separate pln just to keep stairs that I can open and copy/paste... uggg.
I really hope you can bring back the ability to keep created stairs and objects in our custom linked library... not limited to an embedded one. I am fine if once placed that object/stair is embedded, but I need easy fast access for many common stair configurations.
thanks
ps.. it sure would be a great time saver if we could store our user preferences for all the many pen/fill/fonts/etc we need to select every time we build a stair. That would save a lot of time making a stair.
