Problem Punching through faces
-
I'm having a problem punching holes through a face.
I create a rectangle on the face of an existing slab- I Push/Pull it down, snap to the opposite face- and it makes a hole, which is great, but it also deletes the remainder of the opposite face....
What's going on here??

A Face has two sides.
A front and a back.
Depending on your Style the back is usually a blueish color...
If you PushPull a Face the resulting object changes depending on the direction of the PushPull compared to the Face's 'normal' [aka its front's direction].
So If you move 'away' from it you get a solid with two faces, but if you move towards/through it the original face goes and you get a new face at the new position...So, with your 'slab' Face - if it's facing up and you PushPull down you get two faces at the start and end position.
If it's facing down and you PushPull down you get one face at the end position.When you draw a 'flat' face the direction that you pick the 'loop' determines if it faces up or down.
However, if you draw a face 'on the ground' [z/blue=0] it ALWAYS faces down not matter how you've made the loop, this is because Sketchup assumes that you will want to PushPull it UP to form a 3d object like a wall or column.
When you want to PushPull it DOWN it's facing the wrong way to give a fully faces 3d form.
It's easy to fix the Face's orientation before the PushPull.
With the Face [or Faces] selected right-click context-menu 'Reverse' will flip the face over so it looks the other way.
It's a good idea to make a shortcut-key to this tool.
With that face now facing UP, a downward PushPull will make a properly faced 3d slab...It's easier to do that explain...

Okay- I'm picking up what you're laying down-- and yet...
More info: This slab was made on the blue axis then grouped, then push/pulled up to a thickness of 6 inches, them moved up 12 feet to form something like a suspended ceiling.
Through all this I've been very careful to keep all the faces outside out(whitish)- because I use Maxwell Render- and it get's kinda tweeky when faces are inside out (especially with emitter objects- but that's another discussion for another day)
anyways- the problem persists. When I punch through this face from the top- I'm working from a dwg so that's easiest- it deletes the whole bottom, rather than cutting both faces

If you have just pushpull the 'slab' upwards then the two main faces should be parallel and 'punch' OK with a pushpulled face...
When you pushpull the 'punching face' downwards do you click on a lower face's edge, type in 6", or wait till the inference finds the lower face and then click so you know it's exact ?
Once you have made one successful punch then double-clicking onto other punching faces in same-thickness slabs should punch without much more effort... -
THANKYOU!- the double click fixes the issue!
I don't know what about manually push/pulling the second punch face down to an inference makes it weird -- BUT, double clicking it with the push/pull cuts both faces cleanly
AWESOME- THANK YOU!
