I want to make a magazine holder in blender and I try to cut an 'cylindrical' Object out of an Cuboid (sheet of wood). I later want to cnc it so its best to have good geometry. The picture explains best. How would I achieve something like this? It's important to change measures later on and have perfect round corners still.

  • $\begingroup$ did you try boolean modifier? $\endgroup$

  • $\begingroup$ Yes I tried! Unfortunately the geometry was not really nice. Is there a way to technically draw this? $\endgroup$ Aug 24, 2022 at 11:28
  • $\begingroup$ The boolean modifier should be fine for that. Post an image of the problems you were getting when you used it. - You could even use it with an array modifier to cut out all the slots at once for your picture. $\endgroup$

Blender isn't really a CAD application, although there are some add-ons out there to make CAD-like work a little easier.

Just for fun, here's a kit to help make this object, mainly with modifiers, so it's easier to adjust.

enter image description here

  • Starting with an L-shaped face to dimensions, preferably with no internal edges. The concave corner is given a vertex bevel-weight of 1.


  • Bevel (Vertex). By weight. Shape: 0.5, Clamp Overlap, taken to maximum, so the clamp takes effect.
  • Mirror

enter image description here

  • Array, and Decimate (Planar), to get rid of excess internal edges
  • Solidify, to thickness.

enter image description here

  • Optional Bevel (Edge), by angle, to hold edges
  • A little custom Geometry Nodes modifier to put the origin at the bottom left corner.

  • $\begingroup$ Wow this is really helpfull! Thanks for the clear explanation. I'll get to it! I am a cabinet maker and Blender is all I know, so I'll keep draw my furniture in Blender. A friend of mine also wrote a script to output all dimentions for sawing. If it works it works! Thanks! $\endgroup$ Aug 25, 2022 at 13:36
  • $\begingroup$ @DaanVanHelsdingen Great!. You have to think bit like a cabinetmaker to use Blender for hard-surface modelling.. make your own jigs.. take measurements and angles from existing parts.. etc. etc. $\endgroup$
