      Hello All. I am fairly new to Archicad so I hope this topic is in the right place. I work for a Log Home Company and I am trying to make some objects to use in our plans. I have attached a picture of a purlin that I have created. (By created I mean I used a complex profile with a beam and converted to a morph then to an object) I need the beam to stretch on one end only and leave the notched end as is. I have attached a picture. Thanks Much, David Hersey

      Rather than just saving elements as an object you would need to learn to script in GDL so that you can create the elements based on length parameters.
      That way you can control what does and doesn’t stretch.
      It is a pretty steep learning curve if you want to do anything complex but it is very rewarding.
      I have been learning GDL for the last 20 years and I’m still going.

      Can you post a 3D image? From what I can tell, this is an excellent object to start your GDL experience. If you post an image, I think I could knock together a part for you to investigate to figure out how this stuff works.

      There are two free resources:
      1. The GDL Reference Guide, available from the ARCHICAD Help menu. I use this every time I script, as it’s the reference on how all the GDL commands work. Really dry reading, but a really useful reference.
      2. GDL Cookbook, a Google search will direct you here. This is an easier read, but is old (2004).

      There is another worthwhile resource called GDL Handbook by Andrew Watson, but you have to pay for this one. If your company is willing to buy it, it’s worth it (but maybe after you’ve done a couple of objects first).

      Jump in! It’s definitely worth it.

      Of course, in the meantime, have you tried the log wall option in ARCHICAD? I’m guessing that because you work for a log home company that uses ARCHICAD, you have.
