striving for seamless wall/ roof/ slab intersections

Anonymous — Tue, 23 May 2023 13:33:40 GMT

My thought for the efficient production of CDs was to model the building (dimensionally) accurately, but without much detail: just solid white-fill slabs...digital foamcore. Foam walls, foam ceilings, foam floor, foam roof slabs, and that they would all intersect seamlessly in the model, and I could make a section, and fill it selectively with drawn detail as I see fit. HOWEVER, there are all sorts of seams all over the place, even though I have given the same fill to the various pieces, and I have also reassigned the priority number of my non-visible layers. Is it me? Or is it the program? Isn't that always the question? I hope its me, this time.
thanks in advance.

the surface material also needs to be the same to be rid of a joint line in elevation.

ALL surface materials? That is, all three possible planes, on each of two intersecting entities? Or just, say, "exterior" on each?

If you want the foam model look, all of them.

Open the 3D window, activate the wall tool, select all, change materials. Ditto for slabs, columns, roofs, beams, meshes, objects. With the objects, uncheck "Use object materials" and set one material for all.

If the joints still show (BTW, where do they show? S/E, 3D? If in OpenGL, they will always show in 3D) then there is a misalignment.

HTH,

Only on visible faces that are on the same plane, (ie NOT the joining surfaces.).

Well, Im moderately confounded. I made all of the elements the same surface materials, just a blue color for my convenience, and not much changed in my section (which is where these lines are that I care about). I am enclosing a screen shot--so you can see that in some cases, there are clean intersections, but in others, there are not clean intersections. I also selected the elements so that you can see their extents...looks to me like I have sound & appropriate overlap, but, well, maybe not. Plese try to ignore the ugly truss and weird dog-bone things, which are just experiments.

It looks like the problems are mostly between walls and roofs.

Your bet bet in those situations is either the Solid Element Operations or Trim to Roof command.

Make the walls much taller, so they pass through the roof, then cut them off with either of the above commands. (I like Trim to Roof, but SEO does allow more flexibility).

These will cut the wall exactly to the roof line, and they will clean up.

Further to Tom's comments, which I totally agree with, the wall 2nd from the left - is that cut thru a full height window or something? It looks like it doesn't make it to the roof or the floor slab, yet the nodes show that it does.
