Composite Wall Connection Issue – Exterior Layer Discontinuity

Heftor — Wed, 30 Jul 2025 09:42:48 GMT

Hi everyone,

I’m facing an issue with composite wall connections. Two facade walls with different total thicknesses (74mm vs. 65mm) are causing the exterior lime plaster layer to break at the junction instead of merging continuously.

Has anyone solved a similar issue? is there a workaround for walls with mismatched thicknesses?

I have attached the screenshot of the issue + composite wall settings.

Hi,

I've tried to have a workaround with the wall ending tool but it didn't yield good results, the wall makes the 1 skin continuous, even if it is defined as a finish in composite:

You might find something useful in this thread: https://community.graphisoft.com/t5/Modeling/Composite-wall-with-adjusting-thickness/td-p/640626

Unfortunately, it seems like the only solution would be to either model that plaster independently or do the column workaround indicated in that thread

hope this helps.

Hi @CosminF ,

Thanks for the reply, I will take a look to the other thread.

I have tried too the wall end, it made sense at that time but i was no able to make it work.

Regards,

Hector

For these cases I generally draw another composite wall (only with the exterior plaster) in the direction of the plaster adjustment and play around with the wall references line. However in this case due to the quite small adjustments the plaster is not perfect (you can see some small diagonal lines appearing), also you have to draw several additional walls. Probably I would just model this plaster under another layer specifically made for wall finishes.
