hi all, Last month we had a really inconvenient mistake with many machine parts because we missed adding some holes for metal pins, it caused a lot of rework, extra work time, and extra cost. I’d love to see this problem going away. Having a way to visually spot these collisions would be great. So…

hi McNeel team, I posted this over a week ago and no responses. Are we in our team the only ones who see realtime collisions a very valuable feature? If so, why is this? Most Rhino users do not do this kind of mechanical detailing/prototyping? Are all features based on the Architectural market the…

[image] Gustavo Fontana: I posted this over a week ago and no responses. Are we in our team the only ones who see realtime collisions a very valuable feature? First of all thanks for the video, and sorry for not seeing this earlier. You’re not alone, this is something I would love to see add…

hi @Gijs , Thanks for looking into this. I think this will help developers when writing a feature request. For us, using this manual + Grasshopper dependent + brute-force approach won’t work, It works great for a handful of cubes, but I just tested it here in a real world file, One of my working f…

Hi Gustavo, thanks for trying out and the additional info. Of course this brute force approach is not ideal, I totally understand. How many objects were you feeding it? The practical max of this gh sample is about 100-150 objects I’d say. The amount of calculated clashes will grow exponentially. Ev…

What sort of tolerances are we talking about here? Are the intersecting areas always significant, or should this tool detect even 0.1mm thin slivers? I’m asking because that may well limit what methods can be used for this. Breps vs. Meshes vs. Voxels basically.

Hi Gijs, David, Thanks for looking into this. [image] Gijs de Zwart: How many objects were you feeding it? The practical max of this gh sample is about 100-150 objects I’d say. In this case, I was feeding it 68 closed solid polysurfaces. This is a typical mid-development assembly we need to…

Gustavo, when testing these objects, do you need to specify the objects and what type of fit you are looking for? Press vs clearance etc?

Hi Scott, ideally yes. I made a video earlier show-and-telling precisely that. I’ll add you to the thread. Thanks! G

I almost never use clipping planes to find collision but just wanted to chip in with my experiences with overlapping parts being missed in projects. Feel free to turn this into a new topic if this is getting too offtopic from Gistavo’s original request. I mainly deal with cnc-constructions but ofte…

[image] siemen: I’d love to have this as a rhino command. Is everything available in RhinoCommon for me to make this into a command myself? I think you need to use this: https://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_Geometry_Intersect_MeshClash.htm
