X 2 above. Many of the Post Processors (that is Software that takes .dwg .dfx type files), and changes them to "g" code which is the software language that CNC's use will in fact have design abilities although i do not know of any that provide 3D, those that I am familiar with typically only provide std 2D imaging. that includes SigmaNest, Columbus, MasterCam.

All of these programs do in fact require "dongles" which not only are the physical keys that open up the software, they also limit the # of users allowed on a certain software suite. Having sold more than one ESAB Cutting Machine in the past 10 years, this aspect is one that I make sure I inform prospective cutting machine customers who would normally figure: "hey I bought the software, why do i have to pay for another liscence just so that both of my draftsman can use it.??" I got caught that way once..now I let em know up front.!

If you do in fact find someone with a home liscence for Solid Works...PM me. PLEASE..!! I have a very interesting Solid works file that may interest you..!

Thanks,

stk

Actually you can buy Mastercam Design LT, that does not use a dongle. It's around $300 last I checked..probably more than you want to spend still. While it will do "3d" wireframe and surfaces. It will not do solid modeling like the full product Mastercam solids add-on does. And it won't create any toolpaths or generate code. It will read most standard file formats (SAT, STEP, IGS, X_T, etc.), as well as native Solidworks files (.sldprt, .slddrw).

http://www.mastercam.com/LT/DesignLT.pdf

Even the full product, while it will do solids, is not a parametric modeling system like a purpose built CAD system. It will do anything you want with solids, just gets really cumbersome sometimes if you try to get too fancy with it.

Surfcam allows 3D design. Solid Works is the best CAD software right now, not counting the high end stuff like Catia and such.

All CAM software can read dwg. and all CAD software can save in the format, so whatever you choose won't have much problem posting a program.

FWIW you really need a CMM to make (reverse engineer) parts for these trucks.

I should add, CAM software is a PAIN in the ass in general. Most of the generated tool paths are loaded with excess moves and a bunch of just shit in general.

Rant over.

You should be able to find Solid Edge v20 for free on the net somewhere. It is also decent CAD software. You will need a crack for it though.

I was about to ask about this software. I just started working with this some at school this semester. Is it any good? How similar is it to SolidWorks? Sounds like SolidWorks is a much more common modeling software. Is there much of a learning curve to go from one to the other?

Solid works is WAY more powerfull. Its pretty different from solid edge (what I used in school) to solid works (what I use at work), but once you get the general "jist" of one cad program you can usually jump to another and not have terrible problems. User interface is better with solid works.

With that said, Solid edge is a great program to learn on IMHO, and can do pretty much anything SW can do, just not as good

Good to know. Thanks for the info. I played with AutoCAD some in high school, but that was over 10 years ago. You're a ME, right?

We've already been through this once If you have a properly written post processor, and know inside and out how to get the results you want, the code is just fine.

Only in very large production runs, in my opinion, will you see any gain that justifys spending any time editing code by hand. Especially when your customer throws rev changes at you the next run, then you need to start your editing all over.

Unless your post is junk. But I'm a work smarter, not necessary harder kind of guy. Invest the time up front and fix the problem at it's source.

We run parts by the tens of thousands, every millisecond counts. While it may or may not bother you any excess move is more wear on the machine...
