1:1 DXF output from Wildfire

• cncmillgil :

All I can do is confirm that, as I'm not a Pro-E guy, sorry. Good to see I'm not the only one working Saturdays. ;=)

Does it have to do with the units? Is the scale factor always something predictable like 10:1 or 25.4:1?

DXF files are unitless so the exporting and/or importing system has to be set appropriately so that they agree.

Hmm apparently they have some type of designator as to drawing scale scale? not necessarily relating to units/inch/metric

no wierd ratio's like 3.33333: 1 =3D Pro/e sheet size?

true

so how does Pro/e wildfire do it? - thats the system it's being generated from. "Everybodys" cad & cam systems reads that Pro/e DXF file in the same- out of scale.

to the best of my knowledge a line length of "1" is 1 not .332 in any unit of measure. the system that imports that DXF handles the units?

there's gotta be a Blo/e setting to handle that, come on. Geeze this is 2011? aint it. are we reinventing data translation? and why as a default setting would ser named system want to export an out of scale drawing?

All I can tell ya is its not that why with Cimatron , Solidworks & Pro/ e years ago.

"Unitless", yes, that's the import point. So, sheet scale has to be 1:1, same with individual view scales. Dxf_out_scale_views set to yes is supposed to do the automatic scaling. But to be on the safe side, start with a page size that can accommodate the view(s) at full size. But not too big because pro/e helpfully scales stuff up. Purportedly, the units of the model have already been set to ISO/metric, so aside from sheet/view scaling, the drawing should follow the system of units.

Were does one find the "Dxf_out_scale_views"? Is it in a config.pro file as it was years ago?

These drawings are company "standard" sheets & formats We are not the "creators" of the Pro/E drawing & do not want to create a new "blank format" 1:1 drawing in Pro, its redundant- why make more work?

in our case not so helpful scale down to like 3.333 DXF output. Again my question: Why would anyone want a scaled down DXF output drawing? It should be the other way around : default output should be 1:1 unless otherwise specified? Oh PTC you've done it again!

right as long as you stay in the Pro/E environment.

Thx

There is none to the best of my knowledge. When you create the drawings do not scale to drawing to anything other then 1-1 or full scale. When ever I send a dxf file to a machine shop, I send them a drawing (usually as pdf) with all dimensions and tolerances scaled to fit whatever sheet size I choose, and also send a full scale dxf file with 6 views (sometime more if special angles are required) and no dimensions, after all they're most likely just going to import it and don't require dimensions.

PffffffffffffffffffffffffT! with this place

Dxf_out_scale_views set to yes is supposed to do the automatic scaling. But to be on the safe side, start with a page size that can accommodate the view(s) at full size. But not too big because pro/e helpfully scales stuff up. Pro/e drawings don't have any units so they'll follow whatever was set in the model. I've been asked before by vendors to remove the dimensions, otherwise, they have to do a lot of editing. So I regularly include a sheet or two with a bunch of undimensioned views, just for "Save a copy" to DXF. Reemphasizing what Paul said, the key is sheet and view scales set to 1:1.

So....... there seems to be an text parameter file called "current_session.pro" with all of pro's options set. last line reads: dxf_export_format 13

format 13 would be the culprit, I presume dr. watson?

we'll get to the bottom of this format 13, even if the USENET groups suck now.
