Many lines

[Greg_J]

Can MC turn many small lines into a arc?

 

How would I be able to do that?

 

Thanks,

Greg

Draw (in a different color)an arc using the furthest end point of the end line, any one in between, a the end of the last line. delete the multiple lines.

Thanks Rick.

I am missing large segments of lines so it makes it hard to do it the way you wrote Rick. I guess I should have described my problem a bit better.

 

I've tried to trim/break/extend but they are small lines not arc's. I also tried to close arc but again they are not arc's.

 

I am hopeing that their is a function in MC that I can chain the existing line and convert them to a arc.

im like rick, i just create arc endpoints and then close the arc and delete the lines.

[Thee Rickster ™]

Because they are in fact lines you may have to

build the arc from them.

 

Why is it missing segments?

How were they (the lines) created?

 

Got a pic or example?

[Greg_J]

It's a globe, it was drawn in autocad. I had company logo in the spot where the missing lines were. They wanted me to rotate the globe to a different angle.

 

I figured out how to convert the small lines to splines, can I convert the splines to arc's?

Iges that out and send it too me.

If it was a surface include all geometry.

I can fix it, my dad has an awesome set of tools.

 

I have a different software that will do it easily.

It will all be arcs when finished

Did you try the simplify feature? Edit/Simplify.

[Toonz]

If that is a 3D model, just take one of the full arcs and rotate it about the North/South axis.

 

If ALL of the "arcs" are made up with short line segments I fail to see why the 3 point arc command won't work to place at least one arc and then rotate copies.

[Greg_J]

Edit/Simplify says failed to convert splines.

 

It's 2D drawing, I am using it for engraving. 3 point arc just wont draw it right I must be doing something wrong, It works on some of them but I mostly get double lines they don't line up with existing lines.

 

Rick,

You've got mail.

Level 3 is the one I'm working on.

then use break many pieces funtion to change to arcs

[MAKINOPAT]

You could try creating points along each "arc" you are trying to create then create-spline- automatic,then edit simplify. Or have you tried using create arc dynamic starting at the top of a line and creating an arc part of the way down, creating several arcs close to the existing geometry?

[Ocean Lacky™]

i could be wrong...but, if that's a 2D drawing, then you wont get any true arcs.

[Thee Rickster ™]

Send it to Ocean.

 

Its is elliptical and not a globe, button like.

difficult to decipher

 

its like a globes surface grid lines in a 3-d globe structure,

that is tilted on a theoretical axis, then squashed to 2-d

 

Cheers

Greg,

If you draw an arc, tip it 'off axis' and project it onto a flat surface, you will a spline, not an arc as a result.

 

You can use Create/Spline/Curves Spline to join all the small lines into a spline that will approximate an arc.

 

In order to rotate the globe to a different angle, you may need to consruct this in 3D, rotate it to get what you want, and project to your surface.

 

Any way you go, not just a simple mouse click.

and once you have splines, you can do a contour toolpath with cutter comp off and filter on. Then do a backplot and save as geom. I find that it usually comes out with cleaner arcs. then I delete the splines. You will not get just one arc out of it though.

[Greg_J]

My original thought on how to recreate this 2D of a globe tilted would be to create Primitives Sphere with surfaces then tilt the sphere how I want then lock my Z and draw the arc's using that as a reference, but they are not arc's they are ellipses. I also can't click on the points of the wire frame of the sphere.

[Philcott]

Why not just draw a new 3d globe and project the logo onto it? Wouldn't that work?

[Ocean Lacky™]

create the primitive sphere and then create flowline curves on the surface of the sphere

[Ocean Lacky™]

mail, Greg

[JDowe]

I usually have good luck using Erics method

[Greg_J]

I took the model that Ocean sent me and rotated it the way I wanted it to be then I went to X-form Project. Now all I have to do is trim out the lines I don't want.

 

Ocean, how exactly did you get that sphere to have arcs?

[Thee Rickster ™]

i should of sent ya the sphere with arcs right away.

I took to long trying to rotate it in

the exact position as level 3...lol

 

I knew ocean would get on it

[Ocean Lacky™]

Greg

 

I created the primitive Sphere with a surface, then created flowline curves on the surface. Then I rotated it 10 degrees from the right side contruction plane.

 

You will have arcs until you try to project them onto your surface. Then they will turn into splines, or many short lines

Oops, to slow

Ya got mail
