Lot Grade Generic Subassembly Not Part of Corridor

C3D 2026

Built an assembly with a crowned road, a LinkOffsetAndSlope, and a LotGrade subassemblies.  Created a profile view and profile.  Created a corridor. Two things.  The LinkOffsetAndSlope has to be shown as a 25' wide subassembly to be a 15' wide swath in the Corridor.  Biggest deal is the LotGrade doesn't appear in the corridor.

Dwg attached.

Can someone tell me why these two things are happening?  The generic subassemblies sometimes don't work for me.

remember, most of the generic sub assemblies are width controlled from the baseline, not your tie in point, so, if your subassembly starts 10' out, and you specify a 25' wide offset, you'll only get 15'.  So, in the case of your subassembly, you need to specify 35', not 25' because your road is 10' from the baseline, to where the link slope and offset starts.

 

I've never used the Lot subassembly, but, I think it isnt drawing because it is one of those you have to specify a target elevation for the Edge, otherwise, its trying to attach to elevation 0, which isnt buildable.  If I specify to use the road profile that you have drawn as the elevation target, the linework does draw in for the lot area.

I appreciate y'alls reply.  I drew a feature line at the edge of my corridor, offset it the req'd distance, picked it as a target, and it worked, adjusted the elev of the feature line a few times to check how various slopes affected it and it was good.

Thanks again.
