Overlapping entities

[Brendan P]

I did do a search and with no luck didn't get my answer.

I am running a 2D lathe part that was converted from autocad lt.

When I run my toolpath,I keep getting the "there are overlapping entities in the chained geometry"

 

But If I analize chain,there is nothing there!

 

I even tried the findovlp.dll chook,and it finds no overlapping entities!!

 

WTF

 

has anyone had this happen before?

did you try combine views?

now Stork, what would sitting in the cab of a John Deere looking out the windows have to do with Brendans problem. lets stick with the subject

oh, whay didnt you say so

I have had this happen a few times. usually when I am chaining solid or surface curves. somtimes there seems to be two entities when theres not. I have to redraw the chain to make it work. does anyalize chain start and stop nearest your chain point? if it jumps to a different end point somfins wacked

i had the same thing happen recently. couldnt find what caused it . it was were my o.d. tool and i.d. tool overlapped to complete the part .

Brendan,

try DXFing out the geometry and then reading it back in. Or maybe 'squashing' the geometry to the XZ plane. If you are still having problems, email me the file.

Ya Brendan, Autocad splines seem to be a problem sometimes.......I will have to trim them together .

 

I don't know why but sometimes imported DWG geometry will have non tangent fillets, overlapps ect...

[Brendan P]

Thanks guys.

Steve,I just tried the dxf thing,but the same result.

 

I am a little bit busy today,and I just had to work around it for now.

I would like to email you the file,just to see if you can find anything.

 

I will have to send it in a little bit when I free up.

 

 

Thanks

if they are splines that are giving you trouble, try reducing the amount of control points in them by Analyze>Edit=Y

then set your desired tolorence (I usually use somewhere between .0005 & .001). This usually clears up any trouble Im having with splines...seems MC starts getting funky when the ammount of control points in a spline gets up there...

Brendan's problem stems from using chained geometry for the stock boundaries. Seems to be something with the shape of the stock. Tool path still generates correctly. I'm trying to replicate the problem with simpler geometry and then I'll get it over to Mastercam QC.

Thanks for all your help Steve.

Zero I never thouht about that If memory serves there were settings in Acad for points in a spline and patches per surface.....forgot about those......

 

You might be on to something....perhaps there is a conflict somewhere and when you use edit it sync's them out ...

Brendan's problem has been reportred to Mastercam and logged as Bug 8868. Interesting is that you can move the offending horz line of the stock chaining, by as little as a 1/4 of a degree, and the error goes away.

Ooh no,another bug,X will never be released now!!!

 

Thanks Steve
