Making 45° Bevels

I am making a 4" X 4" post for a bed and want 4 - 45° bevels on one top. I have watched many videos and if one did it, I missed it. Can someone help me out.

Can you share your file so we can see what you’ve modeled so far?

Which version of SketchUp are you using? Your profile implies you are using SketchUp 2017 Make but you posted in the SketchUp for Web category.

Hi Dave,
Here is the file and I goofed on where to post this, should I repost or am I OK here?

Does that mean you are using SketchUp 2017 Make? If so, we can just move the thread.

Yes you are correct, 2017 Make.

OK. Moved.

From what you have in your model, just get the Move tool, click on the intersection of the diagonals and move that point up 2 inches. Same distance as from the edge to the center. That’ll give you 45°.

OMG, I bet I was trying to use push pull. Thank you so much.
I got it and am very grateful.

Where do I find the 2017 Make area for posting?

Yeah. Push/Pull wouldn’t cut it for this.

It’s just the first SketchUp category.

Ah great. Thanks again.

Just in case it has not been mentioned, usually standard 4 in x 4 in measure 3.5 in x 3.5 in.

If this is the case, you should pull up by 1.75 in to get 45°.

Another option that requires no measurements/calcs etc, just inference.
Create a square from the midpoint of one side, split it in half and use follow me.

Another way of doing this using only native tools and my philosophy of modelling the more complex part first.

Hi Jean,
Tried this method and it worked real well. It seems more precise,
Thanks very much,
Ken Davis

Thanks for the info here. You are correct on the size of my posts. Not sure where my head was when I drew this up.

FWIW, the method I showed is every bit as accurate as any of the other methods. if you model your post at 3-1/2 in. square and want a 45° bevel on the four sides, move the central intersection up by half that dimension (1-3/4 in.) That’s simple geometry and worth remembering. You can use it for putting a 45° chamfer on the edge of a table top or a 90° V-groove in a surface or modeling a standard countersink for metric flat head screws or any number of othertasks.

Mine is also as accurate.
