Unwanted Extrusion Join

[PhilvK]

After creating a counter profile (highlighted in yellow in the 1st image below), I created 2 other extrusions which will be support framing (at the red arrows below). When I align the one on the left to the bottom of the counter profile, they join. The one on the right doesn’t. How do I get the one on the left to not join the top extrusion, and why is this happening only on the left?

Can you tell a bit more about the situation or better upload the relevant parts?

How is everything created? All extrusions or some sweeps? Is it a single/multiple families? Which category? In-place in the project?

I’ve attached the old version, but since have corrected by deleting the offending extrusion and copied over the other from the outer edge. I’d like to hear what you think if you have time to take a quick look.

Hey @PhilvK

I do not believe that the extrusion got joined because of aligning it...Align tool does not join element and extrusions do not join automatically (it's not coded in Revit, neither for Extrusions nor for any other 3D modeling tool such as blend/sweep...etc). I believe that the Join happened before/earlier and it just appeared when you used Align

What might have happened is that the Join Geometry was envoked by mistake and you applied (unintentionally) Join Geometry sometime before the Align. In this case...at the first instance you wont see the two extrusions joined...After you applied Align then the top segment of the bottom support got joined with the worktop.

To double check...when you flex the support down...check the properties palette/dialog under Identity data - it does not show it is a Solid Extrusion even when it is detached. Extrusions lose that property when they are joined using Join Geometry.

By the way, I gave myself a kudo by mistake when I was giving one to you!
