x move basic

[craney]

Hello, I am working on drilling a shaft in rotation. the end is at x,y 0 and the shaft is drawn towards positive x. the first hole is 1" in and the second hole is 4" in. the first move shows x-1 but the second one is x4. shouldn't the second be -4 or is that decided by the first negative sign? the table should be moving -1 and -4 to give me holes at 1 and 4 on the shaft.

see code below.

thank you!

My guess would be you used the system Back plane to define your 90 degrees instead of rotation top 90°

 

Short of a file, only a guess..

 

but suffice to say a plane is out of orientation

 

make sure you A0 and your A90 planes that the X + axis direction goes the same way

I'm thinking it should look like this, and JParis is right you probably had your cplane wrong.  Make sure your in top plane, and if you need to rotate around your part then change planes.

 

Good Luck,

Frank
