Autoselecting sketch for Extrude Command

Autoselecting sketch for Extrude Command

Autoselecting sketch for Extrude Command

(OP)
I have a sketch on a rectangular surface, and within this rectangular surface is a bidirectional pattern of circles (my sketch). I want to extrude the circles to make a series of pins. My problem is everytime I go to mouse over a circle, the hole rectangle highlights before I can click the mousecircle. It's a red cross hatch that slowly fills the face. If I go to mouseover the circle it renders this red cross hatch once again. I didn't have this issue before installing inventor 2008. Any ideas on what's going on? I hope I explained my problem clearly enough.  

RE: Autoselecting sketch for Extrude Command

Try changing the edges of the rectangular surface to construction lines or removing them entirely from the sketch. This will prevent Inventor from considering the rectangle as a valid closed sketch.

or just use "select other"
or zoom in closer

Both suggestions help the problem, but the issue is inventor is almost 'hanging' while the program renders the red cross hatch of the area I don't want. Could this be a graphics card problem?  

RE: Autoselecting sketch for Extrude Command

Almost certainly. What are your system specs?

Dual 3.0 GHz, 3.5 GB of RAM, WIndows XP Service pack 2, ATI 256 MB Radeon X600

RE: Autoselecting sketch for Extrude Command

Have you tried switching to opengl? What driver is your Graphics card using? Have you installed all the service packs for Inventor?

RE: Autoselecting sketch for Extrude Command

I would go to Application Options and turn off the Autoproject on Sketch Create option for future parts.

And I would not use a bunch of circles to create pins - it is almost always better to use one circle (the most simple sketch) and pattern the feature rather than the sketch.

I have autodesk 2008 service pack 2 installed.
Turning off autoproject does not affect this red hash highlighting.

rollupswx, I agree about patterning the feature. I still have the issue that if I mouseover the larger rectangle it takes a second to fill the rectangle, and I can't then quickly mouse over the circle.

aardvarkdw, your previous suggestion about changing the edges of the rectangle is a decent work around for me. How do I switch to opengl?

I'll talk to IT about updating my graphics drivers.

I said for future parts, it will not effect what you have already created - you would need to delete the autoprojected rectangle.

RE: Autoselecting sketch for Extrude Command

on a side note I would highly suggest getting rid of that gaming card for a real CAD graphics card.
Stay with direct3d..not opengl

RE: Autoselecting sketch for Extrude Command

rolupswx, I created a new part to test out having autoproject off.

mcgyvr, I'm stuck with this graphics card.

I found that Inventor hasn't been running with direct3d, that is most likely the culprit for slow rendering of the selection. I'm going to have IT update direct3d and my drivers.

Thanks everyone for your help.  

RE: Autoselecting sketch for Extrude Command

I wouldn't worry about the graphics card if you are running Vista OS and Inventor 2008 or later in Direct3D. If r11 or earlier on XP, well...

RE: Autoselecting sketch for Extrude Command

The issue was completely the driver. IT said they had updated them last year, but it looks like they weren't updated since 2005. With the latest and greatest, everything works great.
