Graphics problem or redraw problem

[ptc-2800925]

Hi, I just installed the personal addition of CoCreate on my Vista Laptop. It seems to work, but when I start to add a line, the drawing area blanks out (shows blue background) and seems to flash as I move the cursor. As I move the cursor over elements of the drawing, they will become highligted and then disappear as I continue to move the cursor. If I select "Fit" from the tool bar, it restores the image. Is there any setting I can change to fix this problem? Thanks

I fixed the problem by setting the Windows Enviroment variable "SDPIELFORMAT" to "SOFTWARE".

Which graphics hardware is installed in the laptop? (So far, most systems which were affected by this issue were using integrated graphics chipsets.) Thanks! Claus

Mobile Intel(R) 965 Express Chipset Family PCI bus 0, device 2, function 0 Intel Corporation Its a laptop, so I'm sure that it is using the built-in chip set.

Hi, I'm facing the same problem too, but I have no idea how to set the windows environment variable. Are there any other ways to work around this problem? Thanks.

The Intel chipsets are very basic, and do not support OpenGL. So, you have two options.

1. Set the environment variable SDPIXELFORMAT=SOFTWARE

(Setting this tells your computer to not use the hardware graphics acceleration when running CoCreate Modeling Personal Edition)

2. Get a computer with a graphics card that does support OpenGL
