Draw Poly on other origin not having same result

autodeskguest

The first Poly i draw has the correct result but the second who has a other

center does not. Is there a thinking error on just subtracting the new

center value of 75mm

 

  1. Mark components placement area for mechanical clearance

Change Layer tNames;

Change Pour Hatch;

#Center on 75,75

Poly .2 (75 25) @-50 (75 125) (75 118.3) @+31.7 (75 43.3) (75 25);

Poly .2 (75 25) @+50 (75 125) (75 118.3) @-31.7 (75 43.3) (75 25);

#Center on 0,0

Poly .2 (0 -50) @-50 (0 50) (0 31.7) @+31.7 (0 -31.7) (0 -50);

Poly .2 (0 -50) @+50 (0 50) (0 31.7) @-31.7 (0 -31.7) (0 -50);

    Poly .2 (75 25) @-50 (75 125) (75 118.3) @+31.7 (75 43.3) (75 25);

    Poly .2 (75 25) @+50 (75 125) (75 118.3) @-31.7 (75 43.3) (75 25);

     

    The coordinate (75 118.3) is wrong, it should be 106.7 instead.

     

    Poly .2 (75 25) @-50 (75 125) (75 106.7) @+31.7 (75 43.3) (75 25);

     

    produces exact the same polygon as you did it below with

    center (0 0). The ring has a width of 125 - 106.7 = 18.3

    which is the same as 50 - 31.7.

    #Center on 0,0

    Poly .2 (0 -50) @-50 (0 50) (0 31.7) @+31.7 (0 -31.7) (0 -50);

    Poly .2 (0 -50) @+50 (0 50) (0 31.7) @-31.7 (0 -31.7) (0 -50);
