Splines to arc converter

[Joeyls319]

Is there a way to convert splines to arcs in "X"?

 

I can't seem to find it.

Edit - Simplify.

Thanks for the quick reply.

Joey,

 

Edit-simplify will convert splines which look circular into arcs and splines which look like lines into lines.

 

If you've got randomly-shaped splines, you need to use Edit/Trim-Break/BreakManyPieces. Select the spline, click on the button to the left of the green check to tell it if you want lines or arcs, and enter a tolerance value in the field in the middle of the ribbon bar (next to the 'Tolerance' button)

Pete,

Why would one not use break many for everything?

Is Simplify something special for circles only?

Andy,

Yes - simplify is specially made just for circular and linear splines. It will attempt to convert one circular or linear spline into one arc or line (instead of breaking the spline into multiple pieces as BreakMany would do.

Pete,

I think I understand.

Simplify will only make circles.

Break will not easily make circles. Or wont make a circle period. It make tangent arcs and lines within the chordal tolerance to fit the geom.

Thanks Pete

Andy,

 

Simplify will make circles or lines. If you had a rectangle with filleted corners, Simplify will not create 4 lines and 4 arcs. It will fail. In my experience, they must be single entities.

 

I've never seen Break Many Pieces make an arc.

Sure break many will make arcs. It just won't mix arcs with lines. Here's the line/arc button on the ribbon bar:

 

 

Sorry Thad if that's not what you meant.

I meant a single arc, as in the example of using an arc (or hole) that is represented as a spline. Edit-Simplify will convert it to an arc while Break-Many Pieces will convert it into a bunch of tiny line or arc segments.

Bringing this back to the top...

 

I just noticed that in X MR2 that you cannot pre-select or select multiple splines to BREAK into many line and arc segments. I seem to remember that you use to be able to do this - if not in X and X MR1 at least in v9.

 

It can be really useful when needing to break TrueType lettering up into tangentail line and arc segments.

 

 

Anyone have an idea if I am doing something wrong, or is this something that was left out?
