issue with VPORT

[vjedlicka]

I exported my data to a DXF draing using CadLib 3.5
The drawing opens fine with DWG DXF Sharp Viewer,
but not with DWG TrueView 2010.

The error message is
Opening an AutoCAD 2007 DXF file.
Regenerating model.
_RIBBON
COMMANDLINE
_DWGPROPS
_EXPORTPDF
Error in VPORT Table
Bad height:0.000000 on line 1380.
Error in VPORT Table
Bad height:0.000000 on line 1380.

I probably neglected to create something about VPORT.
I do not know what VPORT is. Can you please briefly explain
what might be wrong and how i can fix it?



Thank you

Hi Vaclav,

Could you attach the DXF file that you produced?

Thanks!

It happens with the WriteDXF sample distributed with CadLib.

Nevertheless I fixed the issue by creating a default VPort, setting its height to 1000 and adding it to the model.

I suggest you to update the sample.

Thanks
Vaclav

BTW I could not upload the file because of the size limit, and when I zipped it I realized zip extension is not allowed!

Hi Vaclav,

Could you e-mail me the DXF file (the write example creates 3 files, so not sure which one has your error)? The current CadLib 3.5.6.4 version doesn't create a default VPORT. If you want to create a default VPORT, you could use method DxfVPort.CreateActiveVPort(), which sets the height to a default value of 1.

Thanks,

Yes, that is what I did.

Code:

DxfVPort vport = DxfVPort.CreateActiveVPort();
 vport.Height = 1000;
 model.VPorts.Add(vport);

Without this code I get the error mentioned above.

Hi Vaclav,

Would you mind e-mailing me the DXF file, because I don't yet understand what's wrong. The CreateActiveVPort method does this:

Code:

public static DxfVPort CreateActiveVPort() {
DxfVPort vport = new DxfVPort();
vport.Name = ActiveVPortName;
            vport.Height = 1d;
return vport;
}

So theoretically the height shouldn't be 0 unless it was set to 0 explicitly.

Thanks!
