Using Inventor 11 Professional 1

[pegasusinternational]

When I am sketching whilst making a part (.ipt) the construction lines are not displaying properly.

You only see part of the line not all of it.

I checked the same part on another users machine and it displayed properly.

Graphics card is FX3000 with latest driver.

Not to insult, but construction lines appear dashed. Projected lines appear solid.

If you feel it is a graphics issue, the only thing I can suggest is making sure you have Activex 8 or better.

Correction....Make that DirectX 8 or better.

How did you know that ActiveX 8 fixes it

Inventor 11 made the switch from OpenGL graphics to DirectX. It is quicker generating and relies more on software to generate rather than hardware. One of the complaints Autodesk would get was the cost of the graphics cards needed to run Inventor. So they went to DirectX which, by the way, is the engine used in Microsoft's XBOX. (Hence the "X" in the name.)

Solidworks and Pro-E don't get along with Windows Vista for the same reason. Vista uses DirectX now instead of OpenGL.

Well there must be other setting preventing the lines from displaying correctly as ive just installed DirectX 9.0c, rebooted and tried again and still the same problem.

any other ideas?

Check under tools, application options. Under the hardware tab, make sure that Direct3D is selected on top and below the optimization option is selected.

Try changing to OpenGL if you are already in Direct3D (which I assume as that is the default) restart Inventor and see if that takes care of the problem. If that doesn't then set the lowest radio button on the Hardware tab and work your way back up.

Changing to OpenGL has sorted the problem.
Thanks very much for your help.
