Panning a pdf underlay

[Donald Wardlaw]

I have a graphics regeneration issue and don't know where fault lies.

iMac 2015, discrete graphics, sufficient ram, El Cap (current), VW 2017 (current).

 

If I create two layers, a drawing layer and an underlay layer, same scale, both visible, layer options show other or show snap others;

 

and I put a pdf on the underlayer (bottom layer in stack) so as to draw (trace) on the upper layer,

 

then in order to see the pdf, I have to make that layer the active layer and then switch to the drawing layer above.  Now I can see both layers.

 

BUT, if I pan the upper layer, the pdf goes invisible and I see only the upper drawing layer.  It will not re-display the pdf.  If I make the pdf layer active again, It will display, and if I go back to the drawing layer I still see the pdf, until I pan the drawing layer....

What do you have Tools > Options > Vectorworks Preferences > Display > Navigation Graphics set to? If you switch it to either of the other settings does the behavior change or stay the same?

Ha!  Problem exists with "Best Performance" and not the other two options.  I've never noticed that setting before.

It's new to 2017, and with some graphics cards it is behaving strangely, this is one of the known issues with it. Nothing you did wrong at all.

I stumbled upon a way to trace PDFs a while back. I was using VW2014 at the time. If I switched from Top/Plan to Top, I could see the PDF to trace an existing plat file. So happy with that!
