Question

Remove part of a 3d extrusion

Imagine a shelving unit, I create a 2d rectangle and make a 3d extrusion. How do I then remove more 3d rectangles (or any other shapes) from the 3d rectangle I created to make the 'shelves' ( I don't want these rectangles to go all the way through the extrusion )
The above is just an easy way to explain what I want to do.

Also, I would like to remove sections of the other angles of the 3d shape, not only the front.

Thank you in advance!

This seems fairly straight forward, you may be able to extrude the shape you want easily.

I would also agree that if you want to learn more 3D then eventually you will want to find the 3D program that suits your taste. I don't particularly care for Blender, even with it being free. I really like Maxon's Cinema 4D and would suggest it if you plan on making 3D a part of your work.

    Hi Daniel

    You still need to put a separate back on it to meet the first post requirement of " ( I don't want these rectangles to go all the way through the extrusion )".

    Your point on 3D apps is well made and much of it is taste and what interface suits your working style.

    PS does not support any form of boolean operations, so you can't subtract anything. You have to draw the path the way you want it with all indentations, nooks and crannies before extruding it. Everything else will have to be faked using multiple objects slapped together and then it's up to your texturing and lighting skills to retain the illusion of a solid object. Of course there are limits to all of this, so if you do this regulalrly, learn a real 3D program like Blender.

      Okay thank you. I don't often need to do this but perhaps I'll look into Blender as I find it all very interesting.

      I would also do this in Blender, as it has proper control over the mesh. However, there are a couple of things you can do in Photoshop, which may help depending on what you are producing.

      1. Build the model from several separate extrusions. Merge 3D layers - position the individual models  then group those 3D layers so they will move together.

      2. Use transparency on the material - if you edit the texture map use black for transparent and white for solid - this may work depending on the model where you want the hole.
