Convert splines to Arcs???

[Incogneeto]

Hi Guy's,

Is there a way to convert a set of splines to arcs easily? The engineers are switching back and forth on us (don't know why?) I tried the chook Drill point

But it didn't work or I did not use it properly. All I need is a drill point.

Edit >> Simplify

 

for what would other wise be true arcs and/or straight lines

Thanks JP problem I have with that is splines will not highlight.when in edit???

[Guest]

Nope

 

Just a regular pre-selection

 

Then Edit >> Simplify

 

I keep the .0002" Tolerance and click Green Check

Edit - simplify - all splines .......... done.  As John mentioned, keeping the tolerance around .0002" yields the best results.

1. create a contour toolpath using the spline and use the toolpath arc filtering to fit arcs and lines. (compensation set to "Off")
2 You now need to change the toolpath to geometry from the Backplot menu
using the "Save as geometry" button

3. lines and arcs are created at an accuracy of your choice , Voila !

wow didn't think of that! that's a great way.  what I don't like is that sometimes the path looks good on the screen but faceted on the part. I don't always know how it will come out.

I have an operation saved in my ops library called convert spline that has all of the settings I need to convert splines in this way. Import, chain, and generate. Done! I only use it when I have splines, lines, and arcs all mixed into a chain. If I have a bunch of circle splines, I Edit-Simplify.

 

I can usually tell when my chain contains splines by watching the backplot. When the tool stutters in certain areas, I know I've got a spline.

Some splines will not convert if the tolerance is set too tight.  It depends on how close you need it to be.

 

Obviously you want to be as accurate as possible, but some splines require you to set tolerance to .002".

 

If it is a circle you are going to be within .001....good enough for general work..
