Hi all, When I build an object using dynamic components so I can constrict material thickness (3/4" plywood, e.g.), my parts separate when I scale them larger. Or, when scaling down, the parts overlap. Any thoughts on how to prevent this?

Think of it this way: if both boards are just nested groups inside the DC, then the thickness of the horizontal board will also be scaled vertically and the vertical board will “stick” to this thikness nicely. If you only constrain the horizontal board’s thickness to a fixed 3/4", then nothing chan…

Ugggh. This is killing me. Ok, made some changes, I cant figure out what is wrong with my formulas. Here are the attributes side by side showing measurements and formulas. And here it is scaled by pulling up on the top center scale handle. Note the separation, and the leg drops below the plane…

Update. This behavior has something to do with the fact that I built it with the top first, then the leg. I then flipped long Z axis. I built it again with the leg first, the the top and now the leg sticks to the origin. Which is good, however, the parts are still NOT sticking together correctly…

[image] pcmoor: for top add the Z position Z =table!LenZ-3 Or the general reference Z = parent!LenZ-3 @harpert1 As said before (translated to this new model with a variabel leg length, not a fixed board thickness): the local Z for the top should be at the end of the leg at all…

for top add the Z position

Z =table!LenZ-3
