I've been playing round with Turbocad with the intention of making a crankshaft eventually. It's the V18 deluxe. The snag is it looks as if when you start a solid say a journal if you don't select the maximum number of what they call approximation lines when you go to the real world it will try and put flats on the surface. Does anyone know if this is true. I contacted their helpline and was told it was but the guy was so IT orientated I don't think he understood the question! I cannot believe anyone mad a package with this error in it but before I use it as a coaster does anyone have any ideas.

Rob,
I have been using TurboCAD for years but not spent enough time on it to really learn it proper like. I find it one of the most infuriating bits of software due to the number of quirks, features or bugs. I would love to ditch it but the next step up is a big one. The documentation is incomplete, especially the SDK, which I had hoped to use. Don Cheke http://www.textualcreations.ca/ does some good training documents.

The naming of the versions is a nightmare, and caused me to accidently downgrade my version. TC wanted the full price to restore what I had already paid for.

Regarding your issue. Are you using Solid (ACIS) or TurboCAD Surface for 3D. If you outline the steps to me I may be able to think of a better way?

Rob,

I can't comment on TurboCad specifically but in my day job I work in Cad software development so i have a general insight.

You don't say if you are working in 2D or 3D - can you clarify that?

Usually circles and cylinders are faceted in the graphical representation, but in the undelying model they remain accurate. i guess that you could check by intersecting a circle and a line or a cylinder and a plane at a point of apparent inaccuracy and do a manual check on the resulting dimension. I suspect you will be pleasantly suprised.

More complex surface geometry has to be tessalated and obviously there is a compromise between accuracy and processing time.

Regards,

Colin

I'm working in 3D. I was pretty certain the object when in metal would be right but checked with the makers of Turbocad. They said it did alter the finished result as to how many facets you used. However I was pretty certain this was an IT response Sadly I've yet to meet an IT expert who relates to the real world........
