I have created a rectangle, then converted it into an editable poly. Then I created a circle and converted it to editable poly too. How to make it so that that the circle becomes a hole in the rectangle?

That's called a Boolean operation. You can find a video tutorial here for almost the exact situation you're asking about.

Essentially, it looks like you create a new object with your two objects selected. You'll likely need to make your circle a cylinder first. The new object is a Compound Object of type Boolean. Then in the operations you select A-B (where A is your rectangle and B is your cylinder).

It's still a boolean operation. It's just done with splines that share a common plane. Check the Boolean heading on this page.

Sorry that's correct but I would like to do this without boolean operations to learn how to use edge/vertex manipulation. – Suzan Cioc Oct 15 '12 at 19:13
I'm not sure what you're asking then. You seem to already know how you want to do it. What's there to answer? – Byte56 Oct 15 '12 at 19:21
I don't know how to combine primitive elements (like vertexes, edges etc) into whole, but I believed it is possible. Was I wrong? – Suzan Cioc Oct 16 '12 at 5:54
@SuzanCioc Combining them "into whole" sounds less like "make a hole through the rectangle" and more like "make the rectangle have cylindrical pegs poking out its sides." If you're asking how to make a hole, you don't need to go about it in a less than straightforward way - unless you're trying to do something else! Is there something else? – doppelgreener Oct 17 '12 at 14:45
I need to learn how to work with poly elements. This is an example I stucked at. How to make one outline to be an object and another one -- a hole in first? – Suzan Cioc Oct 17 '12 at 17:02

If you don't want to use booleans...

  1. Use INSET on the front and rear facing face. This creates a square polygon in the middle with edges going towards the corners of the cube.
  2. Delete the new square polygons on each face.
  3. Bridge the new gap created.

Obviously this creates a square hole. However, if you add more verts around the edges of the cube before using INSET, you could later manually shape the hole.

Sorry, this is for a cube... not rectangle. However, the same still applies minus the bridging part. – Inisheer Oct 15 '12 at 19:44

this video shows how to create a circle in your square using the 'loop tools' in the graphite editor. Works perfect, maintains quads everywhere.

Link-only answers are unreliable; they tend to rot over time. It would be better to offer some summary of the steps involved in the text of your answer. – Seth Battin Aug 15 '14 at 4:58
