Can't do a simple subtraction

Recommended Posts

I'm trying to subtract the object, but when I use Boole the subtraction is made only from the primary object (the cube), leaving the semicircle above outside. How do I fix this through the boole? And if not, what would be a good alternative to subtract this solid?

I know it's a silly question, but I'm stuck with it. I thank you for your patience.

This won't be a bug, so have moved to the correct category for you.

 

You haven't given us enough information to be able to tell you why this is failing though - we would need to either see wireframes of the geometry or better still the .c4d file - pls upload it.

  • Ok. Uploaded. I made the semicircle with the geometry pen.

    Why do you want to use Booleans for this? Unless you have a very good reason not to, i'd suggest just modeling it. Booleans are just prone to cause errors like this.

    Yes it's user-error I'm afraid. Everything here is badly modelled - you have internal polygons in the arched shape, which are preventing the boolean working, and the segmentation count in the cap of the other form is ridiculously high, and in notable contrast to the inadequate subdivision in the other directions.

     

    There are basic rules to modelling, and forgive me, you don't seem to be familiar with any of them. If I was you I would pop to youtube and watch a few tutorials on modelling essentials.

    To achieve a more flexible project. Move or rotate the hole if I think its convenient. If I can't boole it, I'll do the modeling.

    That's true, I'm not familiar. I'm watching tutorials and developing that sense these days. Thank you for the answer.

    The hand modelling without booles is undoubtedly the better and more robust way to do this. It takes a while to build up the skills, but the effort is very much worth it.
