Can't make a 2D arc

[jctjct]

I have been struggling with this for hours now. It seems that if two lines aren't in the same plane I can't make a flat arc tangent to them. Go into a front plane, make a line at an angle, back to top plane, create a line from the endpoint of the first line, now create circle edge points , toggle on tangent , input a radius, pick the two lines. Regardless of 2D/3D mode the arc isn't flat. How can I make it come out flat? In V9 this worked just fine.

Why dont you use create arc tangent??

 

PEACE

[jctjct]

I need a specific rad size tangent to two lines. V9 command was Create/Arc/Tangent/2 Entities, the new one is Circle Edge Point/Tangent. It works fine as long as the lines are flat, if not it doesn't make the arc in the current C-Plane.

hit the 2D/3d button to show 2D and you should be good to go. And actually fillet set to circle would be the way to do what you want.

 

 

You may have noticed that there is no 3D cplane anymore - we can be 2D or 3D in any plane.

 

HTH

2D/3D has no effect - they give the same result.

Fillet set to circle gives the same result that I'm not looking for.

WTF I am sorry but if gives you what you want just not the way you want it. That is like saying I can make this part in 30 mintues but I want to make it they I did for years which took 2 days. Sorry I like X yes it has bugs but all the bitching by people ot have soemthing and they got it. I do not use X right now for production. I am using X on the side and I have been a Beta Tester just my choice G-code only uses X now and we do some pretty trick stuff here. I am also the Shop Foreman now so my time programming has been cut by at least 50-60% so I do thing in X when I am home and get better every time I use it. It took me 10 times to get the right click thing down and the way I like but now I do it the way I want everytime just the way I like it. I could bitch about the software sucks or just suck it up do it and it is done and I say this is people choice.

I see what you are talking about jctjct.

The only work around that I can think of is after the 3D arc is created is to use project to get it flat. Not the best solution but it will work.

Steve -

It will project flat, but then it is a spline - not the right arc.

 

Ron -

Don't take it as bitching. This function worked fine in 9, so I assume there is a way in X. I just can't find it.

Ron -

I forgot to thank you for your insight into my problem.

Hey this ones polite, no like the bird

 

jctjct, this is one they definetly need to look at.

 

Bonk feather-head for us

Geezz, do I gotta tell you everything???

jctjct,

 

Until a real solution is found, it appears that you can use surface projection to "flatten" the lines you are using to create the tangent circle and then use the create circle edge point option. The result will be on whatever plane you projected your original lines to. You could then transform back to whatever z depth you require.

 

Hope this works for you.

Has anyone submitted this as a bug??

[jctjct]

How do you go about submitting a bug?

[gcode]

email your file and expaliantion of the problem

to qc---at----mastercam.com

I know I'm a little late on this one, but what am I missing? I think Ron's right--it's not a bug, it's working properly. If you want the arc to lie in the top plane, then project your 1st line(the one drawn in the front cplane) to the top plane. Otherwise, it's like cutting through a cylinder on an angle--you're going to get a spline for an edge curve at the cut.

 

I actually like the feature the way it is now--no more picking the 2 lines to make a custom c-plane just to make and arc tangent to them.

 

Not griping at you, jctjct. I'm just not sure I understand the problem. Maybe throw a file of what you're trying to do on the FTP site?
