Blender beginner here. I imported an image of a floor plan into Blender, aligned it with the grid, scaled it so one unit = 1 foot (it's from the 60s so Imperial). But I'm having issues making the walls:

First I tried putting a loop cut in my first wall and extruding it, but I don't know how to make a cut that's exactly the same width as the existing wall.

So then I tried copying and pasting the first wall instead, rotating it 90 degrees, and snapping it to the first wall. But it doesn't want to snap even though I turned on snap.

Is there a better way to go about this process?

  • $\begingroup$ Ok, if I go with extruding then, how do I specify the exact with of the cut please? $\endgroup$ – Richard Dec 4 '19 at 20:51
  • $\begingroup$ Press e and set the axis (By pressing X,Y,Z) and type in the amount. $\endgroup$ – Yohello 1 Dec 4 '19 at 21:00
  • $\begingroup$ To rotate click off and press r and do the same thing. $\endgroup$ – Yohello 1 Dec 4 '19 at 21:00
  • $\begingroup$ Hello :). You can do it pretty fast using a simple a bezier curve. No messy loopcuts and you can adjust the wall size any time. I can post a full answer if you're interested. $\endgroup$ – Jachym Michal Dec 4 '19 at 23:07

Solidify modifier.

For recent builds (2.82) with the complex mode

enter image description here

Consider using the solidify modifier. Model your walls as simple edges on the plan.. When done extrude to wall height to. Add a solidify modifier to give walls thickness.

Fiddle with settings, for example making offset negative half thickness will keep original edge mid wall.

  • $\begingroup$ Not really. Solidify produces non-manifold geometry if it gets non-manifold geometry in the current 2.81 version while it's improved in the experimental builds. $\endgroup$ – Martynas Žiemys Dec 15 '19 at 16:09

I found the answer here: https://www.youtube.com/watch?v=umhs1dTPP6o

Make one wall the exact width and height you want. In edit mode, extrude the end face of the wall exactly the width of the wall: e, enter number that is width of the wall. Then extrude the adjacent face 90 degrees to that and continue. Easy.
