I am looking for a autocad compatible drawing class library. I came across one at www.vdraw.com, which is what I wanted, but unfortunately, it is a ActiveX component. I prefer to have C++ library that support MFC. I don't mind if it is a commercial product.

Thank you.

Hi siekiew,

take a look at http://www.opendwg.org/
They tell they have a C/C++ library to load/save
.DWG files without Autocad ...

hope that helps,

Hi Zoppo,

Thanks for your response. I have a look at the opendwg, it is interesting, it may solve the file format problem, but still can't do what the vdraw can do, especially in editing of the drawing. I have tested VDraw, it allows us to use it just like Autocad without much effort. What I need to have is somthing like vdraw and at the same time allow me to control the input without going through the ActivX.

Regards,
siekiew

Hi Zoppo,

It looks like I have to go for the VDraw and use ActiveX. Do you have any advise regarding the use of ActiveX in MFC application? Someone told me that it is difficult.

Hmm ... I don't think that use of ActiveX in MFC is too problematic ... it's just not as simple as in VisualBasic, but
not very much harder ... you can simply let the ClassWizard create wrapper classes for you ... then create the control (i.e. in a dialog) and use the wrapper classes generated.

IMO most problems occur if the ActiveX-interface isn't well documented. If it is well documented it shouldn't be a big deal.

Thanks for your advice. I have tested some example and it looks quite OK, but those things like VARIANT, SAFEARRAY, SAFEARRAYBOUND look a little bit scary for me. However, I believe I still can handle that.

Well, yes, you may need to get used to use VARIANT, SAFEARRAY, SAFEARRAYBOUND ...

But, VARIANT and SAFEARRAY are implemented with MFC classes
COleVariant and COleSafeArray, and SAFEARRAYBOUND is simple I think...
