DFX IGS question

[Phil Orenstein]

Just a simple 'I forgot' question (if you don't use it, you loose it). Can an Autocad drawing file be imported into MC with dimensions? Will the dim appear in MC if it's brought in as a DXF, IGS and as a DWG file?

 

Thanks Fellas

Yes

 

But, sometimes funky things happen to the dims. I especially don't trust the tolerancing.

[Rekd™]

Yeah, it does weird stuff.

[JAMMAN]

Uh huh. I scrapped a part on the SAW because it was dimmed in autocrud and they used "fractional". Well Mastercam read it but omitted the fractions from the drawing. Like 11 5/8" became 11.

I second that. Dimension notes get scattered about all over the place. Regular dims are close, but still not in the places they're supposed to be in.

 

have you tried IGES conversions? it don't work, either.

[MetalMarvels]

Personally, I don't trust the conversions until I measure the results in MasterCam myself and compare them to the original file or drawing. On occasion I have had Autocad drawings appear to come in just fine only to discover when trying to chain, that the lines and arcs were on very slightly different planes (sometimes as little as 0.0001 difference). That can be a real pain..... especially when you get multiple overlapping line segments.

Thanks guys. Oops! DXF not DFX. That's how long it's been since using Autocad.

Phil you need to watch out on those DXF drawings if you use the geometry. Most of the stuff I have gotten is no where tangent and most of the entities are not trimmed together.

Gary, what you are seeing is how they draw in Autocad.

I find and alot of engneering dept that use it use it loosly.

They dont take into the thought that some one might actully use the to drive a tool across.

 

I helping a at company trying to get there eng dept to try and draw true to DIM.

 

So that there floor can take the files direct and cut.

DWG translations in Mastercam are generally very good. DXF is a very limited format that has poor spline and dimension support.

[Andy]

DXF geometry comes in fine (If drawn correctly!)

Dim text doesnt seem to come in. No spline support in DXF.

Iges is more comprehensive (If drawn correctly!)

and dims and splines come in fine.

 

Alot of Autocad users are not machining. They print the file on paper and now they have a blueprint. However, the actual geometry may be screwed up in the CAD and when you bring it into MC you have to fix it up before you can use it for machining. In my experience.
