Auto Cyl.

[DeWain Hodge]

I'm attaching a rough skecth of a part I'm going to be writing a program for. Management is wanting the R5.50 ±.01 measured as a 100 point cylinder. I have an IGES file that I'm trying to work with. My question is once I have the alignment and the CAD=PART done if I select the R5.50 as an auto cyl. with a start and end point about .100 from each end 10 rows of 10 points will PCDMIS miss the R3.50 area or do I have to measure 100 vector points and create a cyl?

Thanks,

DeWain

Should be able to to direct where the points hit by dragging the "legs" around where you will avoid the area you need to miss.

Will that allow him to leave a gap as indicated on the print and pick up the cylinder 'top section' along with the 'bottom section'?

I though PC DMIS did not allow this?

If not then he may be stuck with vector points / paste with pattern. That is what I do but then I don't usually have a model.

This is a 3-level autocylinder, I just grabbed the green pointers with the mouse and dragged them around.

Right, but it looks like you cut out a slice in 'angular' fashion - basically altered the start and end angles. It looks like he wanted two full 360 deg portions of a cylinder with a section out of the middle that he had to skip. Sort of a two part cylinder.

Never mind, I read the picture wrong. PC DMIS does that easily enough. While you are here though, will PC DMIS allow me to skip a small section ony in the middle. Imagine a bore that has a second bore perpendicular to it that pierces it. Say a bore with a drain **** outlet on one side. Can I skip that section and capture all the area above it and below it without doing points?

Yes, every level of a cylinder is editable in this fasion.
You can leave some levels alone and move the "legs" on others.

Sweet!

I did not know this. That will come in handy. Thanks.

Wingman-
Just to let you know of another possibility, there is another option called "Void Detection". This option looks at how the hits are touching (or not touching) your cad surface, and basically wiggles the points in the void (hole) so that they are no longer in the void. In the autofeature dialog, it's right near the "View Perpendicular" button. I believe this option first became available in 4.0 or 4.1. Unfortunately, I think you need to have purchased the "Inspection Planner" option to have this functionality available. I know most people don't have this (yet?), but figured I'd mention it anyway. -Glenn
