treat 2 arcs as a circle

[rxdeath]

hey for all you mastercam gurus out there, is there an easy way to get mastercam to register all of my 2 connected arcs into regular full circles without a ton of work?

 

i have a drawing with a grip of different sized holes and i want to use contours, but i have to pick both sides of the arc, which sucks.  if there's a better way i'd like to hear it, but i would also like to know if there is a way to just join the segments into 1 continous line as far as mastercam sees because i'd like to use that process on other shapes as well

 

thanks

Without seeing the geometry I am just guessing.

Possibly make the arcs a separate colour and use the quick mask to select by colour.

Have you tried holding shift while selecting one side of the arc to force the chain?

I believe you could also select both arcs and then join entities to create one circle.

Model Prep -> Optimize -> then create curves to reduce the chances of this happening

Wireframe -> Spline from curves will join muiltiple entities into one.

If you are using Mastercam 2022 pb2 you can convert all selected geometry into splines by typing the following command into the new NetScripting.dll and pressing run.

Mastercam.Database.ChainManager.ChainTolerance = 0.0005;
var chains = Mastercam.Database.ChainManager.ChainAllSelected();
if(chains != null)
{
foreach(var chain in chains)
{

try
{
 Mastercam.GeometryUtility.GeometryCreationManager.CreateParametricSplineFromChain(chain, 0.0005, Mastercam.GeometryUtility.Types.OriginalCurvesDisposition.Delete, 500);
}
catch(System.Exception e)
{

}
break;
}
}

You would save this code in a file called SplineAllSelected.cs for re-use, for example..

Simple ... you can use "Join Entities" on the Wireframe Ribbon to convert all the split circles into full circles.

Is there a similar function for joining non-colinear shapes like a triangle using the same selection method?

[So not a Guru]

On the ribbon, Wireframe/Close Arc

Thee Byte,

"....is there a similar function for joining non-colinear shapes like a triangle using the same selection method?.."

And joining them into a polyline-like entity?

Or a spline with sharp corners?

Yes, a spline with sharp corners, we use this a lot.

Could be a polyline-like entity

Create > Spline from Curves

That takes a number of user selected chains as a parameter, not a group of selected ents.

 

Highly inefficient and unnecessary in many cases.

I keep close arc in my right click menu.

I have "ALT- J" set up for join entities.

You are one coding fool! What is your background if you don’t mind me asking?  Computer Science?

I learned coding on my own and practice everyday.

 I pursued machining and cnc programming in my studies..
