Please post a picture about this part when it's done. LibreCAD and similar free 2D CAD softwares are very similar what expensive "State of art" AutoCAD use to be around year 2000-2004. Current 3D parametric CAD softwares are pretty big step ahead. Yes, there's much more flexibility with in- house production. Please post a picture about this part when it's done.

If I would out-source the job a better drawing would be required. I'm either making this myself on the WF-20 mill or the in-house workshop downstairs will make it on the new Dugard. The internal corners don't need to be sharp, as long as the 76x26mm slide is held securely in place. LibreCAD is only for 2D, so the different views would have to be drawn as separate drawings. If I need front/side/top views of a part it needs to be drawn in 3D and the CAD-program should extract the 2D drawings from that. Yeah the drawing is for in-house use.

Please do add these things to http://wiki.linuxcnc.org I think the next release of LinuxCNC will be 2.5 sometime soon, and that will still be for Ubuntu 10.04LTS. But after Ubuntu 12.04LTS is released I think we will see LinuxCNC 2.6 during the summer of 2012.

I also found that I had to run sudo apt-get install python python-tk idle python-pmw python-imaging to get it going. I made a uge apt-get install-row to get all the packages and I accidently removed Python stuff (The Tk/Tcl versions thing), it might be the cause for the extra step. Anyhow, easy fixin and now have the Sim in 11.10. :) Thanks Anders, got write-up.

Who ever is going to make this needs to know plate thickness, are the 3mm holes through or blind holes, are M3 threads through or how deep thread you want if they are blind threads. All those things can be shown at side drawing, or you must specify those things to this top view. Also tolerances would be important. I think you can use general tolerance, like +/- 0.1 mm, for hole places and for 140*110 mm outside dimensions, but maybe 26mm*5mm slots and 66mm*66mm square have more critical dimensions? How those square corner 26m*5mm slots are going to be made? Sorry about critic, but I just thought to express machinist point of view. I'm sure those things are very clear to you as a designer, but manufacturer doesn't have a clue! You should also draw side view.

Every font is different and these problems are common. for printing this stuff does not show up. For machining we need better lines than the stock font is done in. I always zoom in like that and have to fix the lines to be able to cut correctly. get used to it or create your own lines for the font. Maybe somebody out there has created machine friendly fonts, I have been looking! I work with this type of thing from time to time.

The simulation looks nice. I did not know about OpenSCAM, is it a recent project of yours? I'm in the middle of refactoring the openvoronoi, so the latest code is a bit broken, but hopefully it will come out of that process more robust than ever... Anders Joseph, Thanks!
