Circle from multiple arcs

[cmmguy]

3.7mr3
Does anyone know of a way - other than extracting the individual points - of constructing a circle from arc segments? The arcs are not measured consecutively.

[Matthew D. Hoedeman]

Nope.

[rangerboat72]

Nope.

Tried it, gave up, broke the circles down to a bunch of points and constructed from the points.

Yeah that is what I have been doing too, but thought that maybe I was missing a little secret.

Does everyone agree that this should work somehow? Like a checkbox in the construction window that says "Use Hits"

OMG! Don't ask for an 'enhancement' like that, they'll screw up 17 other things to make that single thing work!

This may be what you are already doing. It works for all types of features.

Create the constructed circle from any three ( or more) features then replace the feature names with the desired features hits as in the below example.

I'll have to try that. Thanks!

If that works I will owe you a beer... no that is not what I am doing and is much easier than what I have been doing.

[tking]

I can vouch for it, do it all the time! What doesn't work for me is the hit[1..8] part, I have to do it one point at a time hit[1] hit[2] etc.

It works, you owe him a beer. Send me one for sugesting that you loop it.

what do you mean... this? circ1.HIT[1], circ1.HIT[2], circ1.HIT[3], circ2.HIT[1], circ2.HIT[2], circ2.HIT[3], circ3.HIT[1], circ3.HIT[2], circ3.HIT[3]


Craig, I'll buy you a beer too, but where did the looping come from?

You need the extension:

CIR1.HIT[1..8].XYZ

what do you mean... this? circ1.HIT[1], circ1.HIT[2], circ1.HIT[3], circ2.HIT[1], circ2.HIT[2], circ2.HIT[3], circ3.HIT[1], circ3.HIT[2], circ3.HIT[3]

I had an idea and opened my piehole before trying it. Looping probably is not the best bet. See my reply to Terry's post.

uh oh...Its friday...
