So. It all looks tickety boo. But, there is a major problem. I can move it around,I can do many things to it,look at it from any angle, but the result is the same,it only shows up as one entity. It doesn't show up as being made up of lines,arcs,splines and surfaces... That's when the penny dropped. It's a solid model. That's why Dom couldn't open it, as its a solid model,not a drawing,but more importantly, I cannot manipulate it to machine it. Yep, you guessed it ,solids was an option in Mastercam v9, and I haven't got it. Mastercam x5 does have solids as an option. They changed their protocol,you buy the software,and there are no add ons. I haven't really got the time to learn x5 in a hurry. So, plan 4b. What if I import file to x5, convert to .igs, export to v9,convert igs to v9? Hmmmm. Hamburger  Split into top and bottom   Flip top over so it's machinable  Write tool paths   Problem solved. Sometimes my Dutch Irish logic helps!Last picture specially for v8ian.... |

 Yellow lines show rapid,non cutting ,positioning movements. Light blue lines show actual cutting path of tool. Happy with that. Will order material next week. Got there in the end ! |

Ah the fun and games of "generic" CAD formats that are anything but. I often have similar issues at work as we use Creo (formerly Pro/Engineer) and if we have to sub out design work it is often done in Solidworks. You'd think you could get them to talk to each other nicely, but Solidworks loves to generate garbage geometry...

You'd think you could get them to talk to each other nicely, but Solidworks loves to generate garbage geometry... ..more likely the "draughts man '" that generates the carp geometry than Solidworks. I have had carp geometry in almost every format available. Put it down to people not knowing what they do. Surfaces that are trimmed to the wrong plane are always good for a laugh, but simple geometry where you have 37 duplicate lines does my head in. More often than not, the amount of time I spend cleaning other people's drawings, would be quicker to draw it myself. Only if you machine off a drawing will you understand the frustration on not being able to get a contour to chain as there are lines upon lines,arcs on top of arcs and branch points left right and centre..... |

Yes, using CAM helps you understand CAD. It was not until I started using a CNC mill before I started to get an understanding of what was wrong with my drawings. This is also why I believe future possibilities of 3D printing for lay people are very much overrated.

When I left my last place, I was using Rhino cad 3D, for my limited knowledge of CAD if found this really easy to use, + everybody else who were much better with cad really got on with it too,

Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style.
Austin A35van, very different------- but still doing it in style, going to be a funmoble

Yes very true, ...Creo has some really nice analysis tools to find and fix the dodgy bits before we send it to the toolmakers, but they are often ignored. For the type of stuff we do Creo does generate much more stable models (lots of free form surface modelling) that's why we pay the extra for it. Spending an extra few days at the end of the project checking draft angles, wall thicknesses, interferences etc is a lot easier than machining out big lumps of injection mould to fit inserts, and our moulders hate finding big lumps of weld corroding from inside out after they have run the tool for a while. Better to stop the issues at source. |

I've always been a fan of staedtler hb. Always worked fine.
Then I discovered the 2b. Wow. Such dark lines.

I also tried softer varieties and eventually reverted to HB, but Staedtler it definitely is (the blue ones). Compatibility with CAM sucks though.

darn- I have this thread bookmarked but hadn't checked in for a few days and thumbnail dies make an appearance.
I could have tried to convert the .stp files for you. I use BobCad/CAM - which has the ability to open and save as a lot of formats. (BobCad gets a lot of bad press but for a home hobby user it is very good (and you never pay list prices that they advertise - their sales people will bargain)
I have a Trumpf reciprocating machine and have thumbnail dies on my list of things to do but have never got around to them. Would you be interested in sharing the CAD files? Or would you be interested in making 2 sets?

Would you be interested in sharing the CAD files? Or would you be interested in making 2 sets? Thanks for the offer of file conversion. Always good to know ! These files are not my intellectual property. They were made available to me with the only caveat being they are for personal use only. Not for commercial gain. If I had to make you a set of dies,I feel I would be going against the spirit in which they were given,something I do not want to do. As for sharing the files,I don't think it's my place to decide who should have them,and start distributing them to all and sundry. That having been said, Brent seems a very obliging guy. I think your best option would be to contact him on the metalmeet forum and ask his permission. I am sure he would agree. If so,I will gladly email them over to you ..Pm me for further details. After a cursory glance,if you do use them,be a bit careful with how to write the program . The file has been drawn with a surface on the underside that looks very pretty ,but,this could try and send your ball nose cutter straight through the middle of the part .... |

Better to stop the issues at source. I used to work for a company that did a lot of aluminium diecasting tools. Welding was a big no no. Any serious mistakes and it was in the scrap and start again. I have never been a fan of stand alone cad programmes. Always felt more at ease using a CADCAM programme that creates both geometry and toolpaths. Mastercam was the industry standard,especially for the plastic injection moulding and diecasting industries,so that's what we went with. Having said that,the surface generating part of the earlier versions of Mastercam was as far away from user friendly as could be. The short term fix was the plug in for Solidworks,the two programmes integrated very well. The later versions of Mastercam, x5 and x6 are a lot better in that respect. I haven't any experience with the very latest versions,so can't say much there.... |

When did we move onto pencil reviews?
Pentel P209 for me in a nice retro French mustard colour. An automatic pencil with nice thick 0.9mm leads. Never thought about looking for them in 2B though.

Look wierd - works great. Always had one with 0.5mm 4H for the guide lines and a 2B for the "actual" work unless it was a proper ink pen job as they were making the etch masks from it. |
