DWG/PDF Export Bug (hidden lines artifact?)

Hi everyone!

I’m experiencing a very annoying bug in Sketchup Pro 2015 (I’ve tried it on SU Pro 2014 and the bug’s still there) :

When I want to export a perspective view of my model in either DWG or PDF file, my terrain’s TIN seems to be invisible so I can see hidden lines underneath it.
This bug appears on some other faces in my model, lot of hidden lines appears instead of the face itself.

It really kills my workflow, making myself spending way too much time in cleaning my vectors files…
Look at the attached pdf if you don’t really see what I’m talking about.

Does anyone have ever experienced this bug?
(sorry for my english, I’m french )

I use SU Pro 2015 on a Dell XPS 15 9530 platinum:

Main Processor: Intel Core i7-4702HQ, 4 cores - 8 threads at 2,2/3,2 GHz
Graphics Processor: Nvidia GeForce 750M GT (2Go DDR5)
RAM: 16Go DDR3
Drive: Samsmung SSD MSATA 512Gb

I load SU on the Nvidia processor instead of Intel HD Graphics chipset.
Hope it will help!

Does it do this in all your exports or just with this particular model?

Is your Nvidia driver up to date?
Is your model very large or very far from the SketchUp model origin (several kilometers)?


Disable the option Use hardware acceleration under Window > Preferences > OpenGL.
