convert many splines to small arcs at once with given tolerence

[techmanDj]

I used to be able to select many splines at once and convert them into small arcs with set tolerence on Mcam9, but when I go Break Many Pieces on McamX, It will ask me to select An entity, not multiple.   I'm working on a geometry with many lines, arcs, and splines mixed.

I believe you want to use simplify spline.

Never mind, I read the post too hastily...

This may or may not work, depending on a lot of factors

First use the command

Wireframe/Spline/From Curves , chain your entities and accept

now you have one spine

now click the Trim/Break/Extend dropdown

select Break Many and select the spline

select the Create Curves and Tolerance buttons , enter your tolerance and accept

 

also

Check the "Curve Chordal Deviation" setting on the Tolerance page in System Config

It's default setting is .001" and that is the smallest value the Tolerance field in Break Many will accept

I have mine lowered to .0002
