converting splines to arcs

[matdaddydave33]

I have a file with holes on the outside diameter.They are showing up as nurb splines.I am trying to do a 5 axis drill toolpath.Trying to convert spline to arc using edit-simplify but it does not convert(trying to make arc so I can draw line to centerpoint and use points/lines).Any sugesstions?

edit >> simply will get many of them

try trim,break many pieces.

 

 

Use this ribbon bar to break selected lines, arcs and splines into multiple segments based on the specified number of segments or the distance between them (segment length). You can also break arcs and splines into lines and arcs. When breaking an entity, you choose to delete, keep, or blank (hide) the underlying geometry.

 

For splines, you can enter a segment number and distance or, you can specify a tolerance based on chord height.

I seem to be having the same problem.

 

I can't find a way as of yet.

 

Try creating a two point dia circle by snapping

to the spline start and the mid point.

 

If you send me a file I'll try it for you.

 

Sad to say I export the splines and do it in a

different software that has create splines to arc

and then import.

 

I have made a suggestion to QC@mastercam to snap to

grid-line endpoints, this way you can draw a

circle by snapping to the gridline endpoints

on the hole in a surface.

 

My friend is a Beta tester and has said this

enhancment is in the next release.

 

Hope it works good

ya might need to be on maintenance to use it though

I like to use the holeaxis.dll c-hook. You just select the inside of the hole and it creates a center axis of the hole. great for 5 axis holes.

the trim break many pieces works.try it.you can convert the spline into lines or arcs.just set your tolerance at .0002.no need to enter anything else.select whether to keep,delete or blank original spline.

when i have to create arc from spline i use create arc 3 pts (endpoint-midpoint-endpoint)

Hey Matt ,

where you get the holeaxis.dll chook?

[Colin Gilchrist]

do a search on the forum. Hole Axis Chook is free from Verisurf (Thanks Ernie!!!). You will find a thread that has a link to let you download it.
