Re: Part dimensions changing when saving
What version are you using? Did you check the save options and make sure it's saving 1:1? Are there more than one drawing view on the drawing page, if you have multiple parts in the drawing are they the same scale factor?

Re: Part dimensions changing when saving
What is your actual workflow to save them as DWG?
Right now I'm assuming that you're creating a SW drawing and saving that as a DWG. If that's the case it's quite possible you are saving a scaled view from the SW drawing sheet. To me, the only way to create a proper file for laser is to right click the surface of the part and select Export to DXF/DWG from the pop up menu. Assuming again your laser programming system does not offer SW file import. I prefer DXF but it's just my preference.

Re: Part dimensions changing when saving
Hi Don,
Firstly, welcome to the forum.
I could be clutching at straws here and way off base, but the first thing that jumped through my novice brain was whether or not the part files were/are fully defined to start with. I don't even know if this will have any scaling affect when saving to DWG files but was just thinking along the lines of basics.
Dave.

Re: Part dimensions changing when saving
Like Bjorn asked, Are you saving them as .DXF's or .DWG's? Saving the actual part as a DXF will keep the part itself true to its size (1:1 scale). If you are saving the SW Drawing as a .DWG, when opening the software the laser uses that reads .DWG files then the drawings/parts may change to the drawing scale you have set for that sheet from SW. I had this issue when sending a saved SW Drawing to DWG. (I was told they needed a DWG and not DXF) to a vendor. I got scaled down versions of the parts I drew, even though the drawings had the correct dimensions on them, the vendor just loaded the DWG file (which wasn't 1:1) and ran them.

Re: Part dimensions changing when saving
I am saving DWGs though the laser will also accept DXF
When I said they change size its not just in the laser
If I try to open the same DWG in SW it also reports its smaller
but as I said , it only does it with files that I have edited and re saved under a new name
new files from a clean metric template work fine in both SW part format and DWG
I will try Bjorns suggestion of clicking the part and exporting as DXF

Re: Part dimensions changing when saving
Hi and thanks to you all for your suggestions
I still dont know why its happening but I do now now when its happening
and why its not happening all the time
The top plate ( plate 1 ) I drew from a new metric part template starting with a blank sheet
I did the same with the bottom plate ( plate 8 )
but plate 2 I made by opening part 1 and altering it to suit and then saving it as plate 2
plate 3 I made by altering plate 2 and saving with its new name etc etc
It seems if I start with a new metric part page and draw the plate then save it as a SW part and also as a DWG
both come out the correct size
but if I start with an already made SW part and alter it , when I save it as a SW file it still comes out the right size
but saving it as a DWG it comes out 171.689 mm instead of 200 mm
I am using SW 2016
I save DWGs by making the SW part normal to the screen ( so the face is flat to the screen)
and saving as DWG
I save all the files the same without any changes except that the ones that fail are from parts that had
been altered ( as a SW part ) and then re named
I have got around the problem by re drawing each part from a fresh clean template but I would like to know
the correct way around it as redrawing everything each time rather than altering the few changes and
resaving under a new name is a lot more work
