AECOsim SS5: "cut solids by curves" applied on architectural and structural objects. How to fix the final geometry?

For the first one, what is meant by "we only want the final geometry of this slab"? If you wanted to remove the feature you can use the Delete button in the Features tab.

For the second, the only workarounds I can suggest are to either A) Trace a new slab using the vertices of the existing slabs, or B) Perform a Boolean Unite, allowing the Slabs to be converted to SmartSolids, then use that resulting boundary to flood a new Slab.

I can see this too where you have an extremely large site (2500 acres) and in my case slabs all over the place.
I can redraw then but a combination (Merge solids would be great) it may have to be limited or take on only the active part.
I do note one issue would be if the solids are not fully co-planar or sloped.
I would able to be able to merge these even if stepped or sloped. And have an option to heal the joints on the underside where gaps occur merging sloped solids.
We are in 3d, after all and should not be limited so singular planes even in ABD.

Xavier,
I think that the Insert Vertex and Delete Vertex tools might be the answer to what you are trying to do. This would allow you to add additional control points to the slab geometry to align with the part that you were removing through the feature cut.

You are correct in that merging two slabs into one (through Unite Solids) will provide underiable results with regards to quantities and thus should be avoided.

WE ran into similar issues as You can add only so many vertices to make a slab work and cutting out stuff does not always work well either.
But as long as two slabs are side by side they should Unify. the problem for he has been that this does not always occur and leaves a line in the drawing which has a meaning if drawn.

The same occurs in DV's for Elevations on items where you might divide by floor and find that the brick shows a brake line that should not be there if the material unifies.

Unification across reference files does not work for me.

Sorry this rambled but trying to find out why something might need to be merged or drawn so complicated. I had the same issue as above but for these reasons.
