Create solid between 2 surfaces

kubastan89 — Fri, 20 Dec 2024 14:46:11 GMT

Hi,

I have 2 surfaces (attached to the post) and I want to create a solid between these 2 surfaces.

I was trying to extract solid from surface at a surface and trying to use Dynamo to extract solid but none of these was able to extract solid.

Does anyone have any idea what else I could try to extract solid ?

Hi @kubastan89,

If the two surfaces are equal distance apart across the whole area (which yours seem to be), the easiest way would be to extract solids from surface, entering the depth as the same distance between the two surfaces.

Hi, I already mentioned that I got an error after trying this method.

What happens when you ry to extract Solids from surface? ie. any error message etc.?

Hi @kubastan89

Are the attached ok?

I found out that your surfaces are exactly the same, with elevation difference 0.62.

If have LOT of surfaces to export solids, then you need Dynamo. If not then you can do it one by one...

Hi @kubastan89.,

Extracting solids from your model worked fine for me, so potentially something up with your setup.
Try extracting Triangles or Points from the surface, copy those to a new session, create a surface and extracting Solids from that.

Hi @nkiakas

I also tried to create a solid using Dynamo with attached script but also get an error.

How did you manage to create this solid ?

Could you attach solid to this post ?

I used the extract Solids feature, worked fine for me as mentioned, Solids DWG attached to my last post.

Hi @kubastan89

Created solid only from one from your surfaces with depth -0.62

Creation of solid between 3 surfaces did not work for me and i did not try any Dynamo script

Actually I don`t know why I was trying to extract solids from surface at a surface instead of extracting solid using just depth. Depth option work fine for me and don`t get any errors.

Thank you all for help.
