Push/pull will not create an opening

Hi! I’m new to sketchup, I am drawing a model of our church building so I can edit and add potential extensions etc. I am have trouble in the fact that I am using the Rectangle tool to make openings for windows and doors but when I push/pull it will not create an opening - It seems to pull out but I cannot see it pushing in at all as the opening stays the same, although when I turn the model around it has actually pushed something through but I just can’t make it an opening.

Any help greatly appreciated as it is getting quite frustrated. I have followed a few videos and tried a few things but non seem to work

This is whats happening

when trying to make holes into a group, you need to enter the group first.

Here, you have a group, and on top of it, on the outside, a rectangle. Off course it can’t make a hole, it’s not inside the group :slight_smile:

The rectangle is sitting on top of the group - double click to enter the editing mode of the group that makes the wall - then draw a rectangle there. It will work once you do that

I have gone into edit the group and then made a rectangle as was suggested on a video but it didn’t seem to work. Should I explode the group?

I have done this previously and it didn’t work for some reason

You have nested groups, groups within groups.
You need to edit the group that actually contains the geometry.

When I watched beginners videos they basically said to group things which is what I did for instance with the rectangle I made for the building walls. Did I nest things by accident? Do I need to Un-Nest them?

Thanks all - I think thats done it. Clicking on the group then selecting ‘edit group’ seems to be working. Is it easier to explode the group when working on it? or not having a group at all? As I say the beginners guides said id have problems later on if I didn’t group things?

Do not explode a group (or component) without good reason! If there is adjacent geometry at the outer level, the geometry (edges and faces) of the now-exploded group will merge with the outer-level geometry. Untangling the resulting monolithic blob of geometry, if you wanted to, would be a pain.

Just double-click on a group or component (or select the group/component and choose Edit from the right-click context menu) to make changes to the group or component.
