Autocad Internal Values

[dlanorh]

Can someone running Autocad 2019 help me out by confirming a couple of internal values. I can't do it myself as I'm working in Autocad 2012.

The values can be obtained through (princ val) . The values are

value              my Guess

ac2013_dwg       60

ac2016_dwg       72

ac2019_dwg       84

Thanks

Unfortunately thats not what I'm looking for. I am accessing the drawing preferences "SaveAsType" variable, which returns an integer value. The returns I can access are as follows:

ac2000_dwg       returns  12

ac2004_dwg       returns  24

ac2007_dwg        returns 36

ac2010_dwg        returns 48

Where ac????_dwg is an internal AutoCAD variable.

From these it is a simple maths to calculate the values for the dxf and template values (+1) & (+2)

But I cannot access anything above 2010 as I'm using AutoCAD2012.

My best guess would be ac2013_dwg would return 60 etc as per my initial post. I have been accessing the values using (princ) on the command line, so

(princ ac2010_dwg) ==> 48

I am just trying to find out if this continues on a 3 year cycle for versions AutoCAD2013 and above or if it differs.

Hope that makes sense.

here you go

ac2010_dwg returns 48

ac2013_dwg returns 60

ac2018_dwg returns 64

dwg2010format (include from R2010 up to R2012)

dwg2013format (include from R2013 up to R2017)

dwg2018format (include from R2018 up to R2019)

but why this concerns you, why don't you use the enumerator values?

The environment variable DefaultFormatForSave does not accept enumerators, you need the number codes. See:

Vladimir,

you 'absolutely' right, but can we do that???

(setenv "DefaultFormatForSave" (rtos ac2010_dwg 2 0))

[Moshe-A]

or that

(setenv "DefaultFormatForSave" (itoa ac2010_dwg))

[dlanorh]

I'm doing it through VL

(vla-put-saveastype (vla-get-opensave (vla-get-preferences (vlax-get-acad-object))) ac????_???)

I haven't tried substituting an integer for ac????_??? yet. I've just been concentration on getting the value and converting it to a string representation. If I know all the values up to current I can accomplish this without having to construct a long associate list.

[Moshe-A]

yes you are good

(vla-put-SaveAsType (vla-get-OpenSave (vla-get-preferences (vlax-get-acad-object))) ac2010_dwg)

the argument for SaveAsType property is the enumerator (look at the documentation) and there is no need to convert it to string like (setenv) requires

if you are using the vlide editor, you will see that the enumerators are in blue that means they are constants and known (defined) in the visual lisp environment.

I'm converting it into a string the user can read i.e.

Current setting ==> 36  ==> "AutoCAD 2010 DWG (*.dwg)"

Current setting ==> 38  ==> "AutoCAD 2010 TEMPLATE (*.dwt)"

This will be incorporated into a toolbar along with a button to allow users to toggle between 2 or 3 formats before a "save", "qsave" or "SaveAs"

only saveas has a format option

if you still have difficulties in finishing this tell me more what is your goal?

I agree, but typing "save" or "qsave" on a new drawing brings up the "saveas" dialog, also changing saveastype in an already saved drawing forces any "save" or "qsave" command to the "saveas" dialog with the new saveastype already set.

We have clients who run multiple versions of AutoCAD as well as other design packages, and they require drawings in (*.dwg) (*.dxf) and (*.dwt) formats. This is just designed to streamline saving the same drawing into different formats.

'clients' you mean consultants (the real clients ask for PDF or DWF) and you are totally spoiling them for free.

cause you could email them a link to download DwgTrueView. as long as you keep serving them on silver plate, they won't even think of upgrade but if you 'transfer' the responsibility to them and they will see the time they have to spent for converting files, maybe they will think again.
