Solid Extrusion Problem

[bob bak]

I'm trying to project geometry (the onto a solid surface which is curved and I'm getting a planer chain set error. I'm a student and new to mastercam and would like some help trying to figure this out. The file was uploaded to the ftp site, is located in the solids folder and is named bbakguitar.mc9

Any help with this would be greatly appreciated. It is part of a Senior Project Graduation Requirement for my school.

bob,

i looked at the file and was able to project the B fine. I saved it back as bbakguitar-SFA.mc9 . All I did was a 'Create-Curve-Project', picked the solid, then window selected the 'B' and projected normal to the Top view.

Stephen,

Thank you for the quick reply. I was able to project the "B" onto the selected surface but the problem that I'm having is trying to extrude the "B" into the solid. I'm trying to extrude the "B" so that its depth stays equal to the surface of the solid. When I do this I get a "planer chain set" error.

Hi Bob, have a look at the file bbakguitar-simon, what I did is extrude the outside geometry of the B (add boss) and then extrude the 2 inside chains (extrude cut) and that's it. You problem could also be the version of MC your using, I use V9 SP2. HTH!

Salut Jean-Simon,

 

One more post and you will have earned your avatar. Have you given it any thought?

Hi Phil, no not yet, I'll need to have something original. I'll work on that. BTW I haven't forgot you, it's just that we're kinda busy, I made some searches but I think the best way will be to walk around and find a place, anyway all the pubs are on the same street. Sorry for hijacking!

Thanks simon, but what I'm trying to do is project the "B" onto the curved solid and then extrude(cut) the "B" into the solid making a pocket that follows the surface of the guitar. I've projected the "B" onto the guitar surface but I can't extrude(cut) the "B" into the surface without getting an error.

Not seeing the model, I'd say to extrude the non-projected B onto the solid. Create a surface from the solid face the extrusion will intersect. Offset that surface however high you want the letters, then trim the solid to s surface.

 

HTH

Have a look at the file again, I used a sweep to do what you wanted ( I hope that's what you want now). If you want to know more in depth what I did, let me know. HTH!

[bob bak]

simon, thank you very much for all your help. Do you know of any way to keep the depth of the pocket the same? If you look at the file you did, the pocket is deeper on one side than the other.

I just uploaded bbakguitar-g.mc9 to the FTP.

 

Created a surface from the top face of the solid, then offset it down .1 (you can use whatever depth you want). Created the extruded solid from the B and made sure it was long enough to go past the offset surface (5 inches). Trim the solid to the offset surface, then boolean remove it from the guitar body.

+1 to Glenn!

Yes....Thanks to all of you who helped out. This will really help me with my senior project and for years to come.

That's a good thing. What's your senior project of? "D'OH!!" I just re-read your original post and answered my own question. Saved by the 15 minute edit feature. Which school are you attending? It's nice to hear there are schools in our area that are offering Mastercam as a part of the curriculum.

 

The future needs of our country will depend on bright, knowledgeable people in the manufacturing industry. It's hard to imagine anything that we touch which hasn't been manufactured somewhere. Too many Americans don't realize this or loosing jobs overseas would be a larger issue. Especially in this election year. I'll get off the soapbox now.
