Trim problem

[Reverend Turk]

I created a drawing which is a square. I then created and circle over top of the square. The I used solid extrude to make the square a pyramid shape and then solid extuded the cirle down to meet it at a particular point. I am now trying to trime away the cylinder so I can leave just the partial pyramid with the radii of the cycliner cut out on all sides. When I try to use solid trim nothing happens...

 

I am new to this and have been learning on my own with lots of seat time and the help of this board. Any suggestions on how to accomplish this??

Try Boolean-Common. That may be UG terminology. I don't have a solids seat near me at the moment.

It sounds to me like you would want to use one of the Solid Boolean features. The icons next to the features should show you which one will give you what you want.

[LansB]

Yep.

 

Add, Remove, and Common

Ok..I have done that and I end up with what I was gunning for. Now is there a way I can seperate the solid so that I can grap one side of the pyramid and lay it down flat so I can machine that piece with the ellipse? I hope I am explaning this correctly!!!

[Thad]

I don't understand what you want to do.

Ok...I now have a pyramid with four sides where each side has an elliptical cutout. I need to make these four pieces individually and then weld them together in the pyramid shape but I had no way to get any dimensions off of the elipse. So i wanted to draw it as a solid so I can easily remove the extruded portion leaving me with the elliptical cut outs. Now I want to take one side and lay it down flat so I can get the proper numbers from 0,0 and cut out the part on the water jet. I wasn't sure of another way to get that information since all I was handed was a hand drawn sketch with virtually no dimensions.

afit,

 

sounds like a good time to use an alternative wcs.

 

you should be able to define a new wcs dependent on your 'flat' side of the pyramid using some of the geometry options.

once you have created that, set it as the active wcs and go to a top view.

 

i think that is what you are asking...???

 

hth.

[Thad]

Can you put the file on the FTP?

[Reverend Turk]

Thad...Pyramid.mcx is on the ftp site!!

[Thad]

I'll check it out.

 

BTW, you should've put it in the MCX folder. I'm sure Jay will move it.

[Reverend Turk]

Sorry...first time...guess that makes me a virgin

[Thad]

I get errors about not being able to generate the solid.

 

Thad

[Reverend Turk]

Stupid Stupid Stupid

 

 

I will go back and try to regen the solids and see what happens...if not I will just have to red draw the thing and re post it on the FTP. I will let you know when I am finished. Thanks for the help

[Reverend Turk]

I now have the new file in the MCX folder on the ftp....see I do learn!!!

[Thad]

Jason,

 

I put a file on the FTP called Pyramid-Thad.MCX. See if that's what you want. I saved it in my new WCS with one face flat. I think all sides should be the same. I also put my construction geometry on level 10.

[Reverend Turk]

Thad..I don't see your file in the MCX folder

[Thad]

Refresh the screen if you still had it open from when you put yours up. In the details view, it's right under yours.

Thanks for all the help Thad I owe ya

[Thad]

Glad to help, bro!
