I'm new at designing parametric families, and I need to design a specific ladder:

Problem: I designed a parametric ladder around a 152.4mm (6") wall, and the moment I try inserting it in a thicker or thinner wall, only one element attatches to the face of the wall while the rest attatches to the wall's centerline.

Goal: I'de like to change the original reference to my whole ladder so that I don't have to start it again from zero.

Help? Suggestions?

Thanks in advance.

Suggestion... Download the families guide from the autodesk site to help you understand how to build families.

If this is truely a wall hosted element (not sure when you write "a 152.4mm (6") wall") .  The wall hosted family's wall can be adjusted in thickness.  Typically, you should flex this wall to see if your family works correctly at other thicknesses.

I like to build wall based families around a reference plane that is well away from the wall initially.  Before closing the family, I move this plane back to the wall face.  The reason I do this is that Revit will create relative locations for you element based on the wall.  That is what apparently happened in your case.  You can still probably fix your family by defining where the erooneos attachment iends (connection).

Thank you WWHub, it seems like the way to go. I'll have to check it out later since I'm having some delivery date issues at the moment. For this project's sake, I'll just have to make it volumetric and non-parametric.

Thanks a lot!
