Struggling with weird results when complex profile walls meet - hanging geometry?

Davef_dci — Thu, 09 Feb 2023 17:43:25 GMT

Hey folks,

I'm trying to learn how to use complex profiles and I thought a good opportunity to try one out would be to create a complex profile consisting of a concrete basement wall with rigid foam insulation. I'm proposing a "tongue-and-groove" interlock between the footing and the basement wall (with 6mm poly capillary break - which I am not currently modeling).

When I try to intersect two basement walls I'm not getting a clean trim - the "tongue" on one wall simply keeps going some distance beyond a clean trim. It doesn't happen on every wall - only on some.

Any idea what I'm doing wrong???

Thanks!

Hello @Davef_dci,

Change your basement walls into basement beams.

I would have played with the reference line position, or the materials priority....

How they look on floor plan?

I suggest reducing junction order value for the wall exceeding to out, for example change it to 7 rather than 8.

Can you show us the complex profile?

Also if you draw two walls away from the other structure and they intersect at the corner, what do they look like?

Maybe something else in that structure is affecting how they trim - other walls or beams or the slabs?

The tongue is intersecting with your footing? Put them on layers with different Intersection Groups? Sometimes just changing the junction order can help.

I had this problem a few times, mostly such unwanted artefacts are caused by intersections with elements of the same kind (probably walls in your case) on different stories. As mentioned here by @Christophe Fortineau you could change the profiled footing elements to beams or as @Lingwisyer proposed change the footing layer intersection priority number different to the one the walls-above-layer has.

Doing footings as Beams is probably the better way, as you get a few extra options on how it looks uncut.

Hi,

check the overlap of the reference lines between all the walls, the more the lines overlap, the more this problem appears, from what I see you have several complex profiles overlapping

Thanks for all the suggestions. I'm not exactly sure what solved it I but I moved the hotspot / anchor point on the complex profile and redrew it a few times and the overlap went away. I think it's possible that one of the corners was at a different elevation?

Not sure what fixed it but something did?
