CLOSING CHAINS/CONTOURS

[Mike@Dive Lab Inc.]

Hello everyone, I've been having issues when I want to create geometry that requires closed chains revolve for example. After I draw the part,then fillet some edges I seem to have gaps somewhere that won't allow me to revolve. when i select the geometry to revolve by chaining, it shows me the start and end of the chain. The end of the chain should be where the gap is right?? I can't find the gap if I zoom in. I've tried analyze contour and chain and didnt get what I was looking for. My question is how do I pin point exactly where the gaps are so I can close them.

 

Thanks

When I have problems with a chain, I will simply pre-select the geometry as a chain and look for where the arrow stops on the chain.

 

Then you can zoom in on that area and find why the chain stopped there.

That's what I was doing, I'd zoom way in at the red arrow, but saw no gaps, usually what I do is erase the lines and re connect them, just looking for a faster way to do it. I only seem to have that problem after I fillet

 

Thanks

Did you check to see if maybe there was some "overlapping" geometry or something underneath. That happens to me sometimes when I project geometry. Just a thought.

Have you tried analyze chain?

 

It sounds like you might have overlapping entities.

I got it, it kept stopping at this one fillet, I erased it and re did it, its still stoping at that fillet I went ahead and selected the next line to close the chain and it revolved o.k.

 

the chain still stops at that spot, tried a area selection and it worked fine

 

Thanks

Do you have color or zdepth maske selected? This can often cause a chain to stop for an unclear reason.

Mike,

 

You could try squashing everything. In V9 it's Xform-Squash. In MCX, it's under Project. That'll make sure they're all on the same plane. A quick check of the iso view may reveal it too.

might want to try the alt c and pick the findovlp chook. Im wondering if there isnt overlapping entities..

sounds like duplicates to me. try deleting duplicate entities.

I'm with you Storkman, sounds like duplicates to me also.
