Collision detection?- Answered

I remember hearing something about collision detection, but really have no idea about it, I have a building and would like to check if I have managed to draw floors and columns etc through each other. That is check if solids are overlapping/intersecting, is that something that is possible in Bricscad? or am I getting mixed up with some other idea. Or was it an addon.


  • The INTERFERE command is what you're looking for.

  • That was the one, I just couldn't think of the right word, brilliant 5.7 million interference checks 203 problems found and of those only six where worth worrying about and solved 90% of the volume (concrete) errors. I hope our estimating team can live with the remaining 0.016% margin of error that the rest of the errors account for.

    Would be interesting to see if these small interferences are caused
    by imprecise modeling or by rounding issues.
    Because INTERFERE would be a nice way to check geometry for

  • Oh definately down to me, and getting used to how things work. Coming from years of using Autocad LT and then trying to model a helical ramp in a parking garage caused a few of the big problems, some of the others I'll have to take a closer look at, but still user error finding which tools are best for the job.

  • So far I have to think Bricscad makes it a) very easy to draw something
    unintentional and b) there aren't much options to check that while drawing.
    As for 3D I went from Polysolid down to simple Cube Tool already.
    At least things stay rectilinear that way :)

Origami is the Japanese word for paper folding. ORI means to fold and KAMI means paper and involves the creation of paper forms usually entirely by folding.
