Can't delete a face

scott216

I am trying to draw a rectangle inside a bigger rectangle and then delete the face of the smaller rectangle so there is a hole in the bigger one. This is pretty straight forward but it's not working. I only have problems in one section of the large rectangle. If I try to make a hole somewhere else it works fine.

See the attached screenshot, I can't delete the select face. When I do nothing happens. If a draw a rectangle a couple inches away and delete the face it works fine and I have a nice hole in the big rectangle.

I've attached the Sketchup file. I'm using SU 8 on a Mac 10.7.5

I can't deleted selected face

Here's the sketchup file

Your guide lines are not directly on the face your trying to erase. move them down to the face and redraw the rectangle. Whala =D

The face you are trying to delete does delete but it is a separate face, not a face within the larger face.
You have drawn it using the guides, but they are ever so slightly above the other face. If you use the push/pull tool it will connect and intersect with the larger face and you can remove it and the extra edges the p/p will create.

Thanks. How were you able to tell the guides were not on the face?

Here is a way: zoom towards the surface and you'll see the guidelines that disappear.

Here's a tip to cover that situation. When you draw guidelines parallel to an edge that are supposed to lay "on face" start your guideline on the edge, move the cursor up/down a bit on the edge and then pull towards the direction you want. Nothing new here.

But, instead of leaving the cursor on face where you want the line to be, move the cursor to some alternate perpendicular (or so) edge on the same face. This forces the guide line to stay on face. At that point you can enter the offset distance in the VCB or move along that edge to the desired offset location.

To test if 2 perpendicular (or crossing non parallel) guidelines are actually intersecting, place the cursor on one GL and move it to the intersection. You should see a little red X. That indicates GL intersection.

If all you see is a colored dot, the lines do not intersect. The dot means the point at the cursor lines up axially with both GL's.

This works with GL's and edges as well.
