API-question: SaveAs to AutoCAD-format (.DWG ) will produce drawings out of scale...

Hi,

anyone else seen this?

I use a macro to output a batch of drawings (retval = ModelDoc2.SaveAs4 (
Name, Version, Options, &Errors, &Warnings )) to AutoCAD (.dwg) format which
works fine except for the majority of the AutoCAD drawings being out of
scale.

If I do a manual SaveAs they will come out just right, i.e. in scale...

Anyone?

TIA, KimSky

 

I have noticed that scaling is not working in every case for some reason
that I haven't figured out. When saving "manually" as dwg/dxf it fails to
create 1:1 drawing in some of the cases.

Same kind of behavior with printing;
sometimes portrait drawing prints out as landscape if I don't use Print
Preview to check (and fix it if it's wrong) it
first. Both issues are very annoying because you never can't be sure how
it goes before you try and this makes usage of macros quite unpossible. I
have told about these issues to my VAR..

 

If you try a regular SaveAs look under options there is an option for the
output scale to be to the model and not the drawing. This should be set
before your save as in the API. Unfortunately I don't know which call would
be used to set it. I thought it would be one of the UserPrefs but I
couldn't find it. (it is always possible that it is simply broken) Maybe
email api support. They may point it out to you.

DXF
Type of Setting

Enumeration System-Level Document-Level Comments

swDxfOutputScaleFactor Yes No Specifies
value to scale DXF output; double value.

dxf and dwg use the same settings. well it seems that way.

 

If you want to save with the "1:1-scale" setting and the drawings or
multiple sheets have a different base scale then: Yes ;-)

Unfortunately there is a bug in SolidWorks (at least since 2001Plus,
where I first discovered this). I got an API related SPR (#132909) for
this. The problem is, that with the "1:1" option set in the export
dialog SolidWorks will ALWAYS use the last setting for the basic
scale UNTIL you open the export dialog again.
Then the basic scale is reset to the current value.

This is also true if you try to export the sheets or multiple drawings
manually WITHOUT reopening the export dialog for each sheet again.
May be it will help if you also send this as an error report,
so SolidWorks will finally fix this.

I'm sorry, but the best solution right now is to make sure, that all
sheets have the same scale set; I know, that this is not a good solution
for the daily work, but I have no better suggestion right now.

Bye,
Stefan
