How do you handle splines?

[medaq]

I have a customer that uses Tebis. And when his files come in, The whole part is made of surfaces and splines. And for me to recreate the geometry. I have to individualy modify-break-manypieces-by error. And do this for every line individualy. After a 1000 splines this process gets very tedious since there is no modify break manypieces all splines. If I try and convert to arcs. Stuff just goes everywhere. Any ideas on how to easily break up so many splines?

Have you tried deleting splines and create curve all edges?

[medaq]

Creating curves on edges is about 40% succesful. Which is what baffles me to death. I will have a flat surface and create a edge curve. And one half will have nice line and arc info. The other side will be a spline. Driving me nuts atm.

What would Edit...simplify do for you? I don't know if this would work or not, or if you've tried, but take a look.

I wonder if adjusting your spline allocations under screen configure might help? (just guessing now)

[billystein]

You might try this.

It doesn't work 100% but here goes.

 

create solid from surfaces.

create curves all edges from solid

40% sounds like your using X Mr1

Its supposed to be fixed in Mr2 ?

Machine them as as. Except for the toolpath(s) where splines aren't allowed (2D Swept comes to mind), and when I'm going to use tool radius comp in the control. Then I break or re-create the geometry needed just for those particular operations. Doing otherwise is a total waste of time, IMO.

As john said edit/simplify should do it

Oh yea my limiting factor, Is we are using mastercam 8.1. Might be no solution for my software, but have to ask anyway...

Could we be seeing a possible reason to upgrade here Jim?

Hard to pay for upgrades and monthly fees for one thing that takes a little longer once a month.

In version 9 there wasn't a way to "select all splines" with Modify/Break/by error, each spline needed to be picked. There is a Modify/break/Splines to arcs but if the spline didn't lie within the construction plane then the spline won't be converted. X unfortunitly works the same way. So there isn't a "takes a little longer once a month" scenario happening here. I'll see about putting in a request to be able to select multiple splines.

I also post the same problem today, It is surprise if you use v9 and create curves on all edges, It give nice lines and arcs .It doesn't give any splines but this is not happening in x.

thanks

i wouldnt use wires came from other softwares... i would make a flat surface in the middle of the model depend if it is for lathe or milling... i would create curve on surface intersection..
