What am I doing wrong with push/pull
-
Hi
I'm fairly new to sketchup but have used AutoCad for a few years but I'm struggling with erasing a face when using push/pull.I've created a rectangle and then used offset to create a smaller on inside of that. I then want to remove the piece in the middle so I'm left with a box section. When I do this it just pushed right through so I've got the smaller rectangle protruding out the other end. Any ideas
Thanks

Hi Keith,
When you push the offset face down inference any of the lower face corners to align and then click. This should remove the face and leave the surround shell.

When you are PP'ing that smaller rectangle, snap the PP tool to a bottom element (edge or endpoint) to "stop" it there. It should then automatically remove the bottom face, too.
Edit: Rich beat me...

Place a reference line on the outside face of the box where you want the pushpull to stop. Perform the operation and mouse over the reference line. It should stop there. You can also input a distance in the VCB in the lower right corner of your Sketchup window. Alternatively, start with a flat rectangle, pushpull the "floor" to thickness, offset to taste, perform pushpull and type in a value in the VCB how tall you wish the walls to be.
I expect that everyone is going to pounce on this one. Yep.

When you PushPull a face inside a face by an arbitrary amount it will either stop inside the form [making a recess] or pass right through it leaving your 'projecting box'.
This second version CAN be useful if the two faces of the object you are extruding through are NOT parallel - because you can the select the 'back' face and use Intersect to cut it where your protruding box is sticking through and simply erase/delete the unwanted edges/faces.However, when the two faces are known to be parallel [like in a wall or floor where you have probably already PushPulled them and can be confident that they are therefore parallel] the simplest way to PushPull the punched hole 'in one go' is to start PushPulling the face into the form until you are approximately at the expected depth and when that face starts to z-fight - front/back-materials visually ripple - click and the extrusion is made the exact depth and hole-punches.
A similar way is to start the extrusion and then change the view so you can see a side part of the back-face and click [snap] on that - it should again punch the hole OK.
Yet another way is IF you know that the two faces are say 123 units apart start the PushPull and type 123 +<enter> and again the extrusion will match the thickness and punch the hole.
The last used PushPull value is remembered for the next PushPull, so if you have several faces punching the same depth holes you simply double-click on each of those to use the same distance, without any further picking or typing...

Thanks everyone, I did it. Simple really!!
I can get one with the design for a Radio Controlled Lancaster which I going to use a CNC hot wire foam cutter for. On my 3rd Lanc now but I want to do my own and not somebody else. Some stuff on my website may be of interest http://www.rckeith.co.uk/lanc.html
