moving wcs

[doyleg]

is there a way to move the wcs and/or rotate it without having to rename the wcs. i've tried doing it like the help page says but it still won't just edit the wcs without having me rename it.

Not a system one.

 

You can copy a system one and rename it and do what you need but once it changes you'll have to rename it.

 

I create WCS origins all the 2 using 2 lines, after I name it, if I have to move it, I just move the lines and they are associative to the new wcs, so it will just move and not ask to be renamed

I don't know about rotating but to MOVE a WCS, I change the coordinates (yes, even on SYSTEM views). For any wierd rotation I use the 2 line method as well.

thanks - i'll try that

yes, i was able to move the wcs without having to rename it. however i can't rotate it without having to rename.

What if you base your WCS off of the 2 line method to start off with, and then rotate that geometry later on if you need to? I forget if it will auto update after you do that. Let me get the machine running, and I'll do a quick test.

I just did a bit of a test. it looks like if you base your original WCS or whatever off of the 2 line geometry deal, you can then go and rotate that with no need to rename your WCS setups. This method though, will mess with your toolpath setups.

thanks andrew. i always rotate and transform the original to the top wcs and then change the wcs for other operations on the same part but with a dif view. i'm trying to keep my mc files as small as possible so that i don't have that much of a lag when doing anything (x-form, rotate, saving and on and on).

If my WCS is set to top and I click the WCS button on the bottom toolbar then select rotate WCS It asks me to rename it unless I rotate it to a position that ends up being a named view. For instance rotate about X 90 degrees is the same as the front view. In this case the system automatically sets WCS TO front.

If you rotate a WCS it is my understanding that you will always need to rename it. This is because Mastercam uses a matrix to define its world position including angles.

 

If you go to the WCS manager right click on any WCS and select info, then you see the information.

 

For example Top view is....

 

Name : TOP

Comment :

Origin : X0. Y0. Z0.

Number : 1

Matrix : X1. Y0. Z0.

: X-0. Y1. Z0.

: X0. Y-0. Z1.

Associative : No

Color : 12

Used in toolpath : Yes

 

 

Top view at 45 degrees would be

 

Name : TOP @ 45

Comment :

Origin : X0. Y0. Z0.

Number : 38

Matrix : X0. Y-1. Z0.

: X0.70710678 Y0. Z-0.70710678

: X0.70710678 Y0. Z0.70710678

Associative : No

Color : 69

Used in toolpath : Yes

 

0.70710678 is the sine of 45 degrees so gather that Mastercam uses the infomation to trig out its world position.

thanks guys, it does explain alot.
