Is the world coordinate (gpntwc) dynamic or static in the viewport?

I draw two construction point on the WP. and then move one point to the other point position.

The whole  process recorded by loading recorder.

Show the code as below:

I found that the point world coordinate not the same.

Is the world coordinate (gpntwc) dynamic or static in the viewport?

Best regards.

Hi Justin,

You are drawing world coordinates onto a WP, resulting in a 2D coordinate on your WP.

If you would reposition the WP, the coordinate of this point will change of course.

A viewport is a window onto your world coordinate system, so if you will zoom, pan, rotate, it will visually be another location.

The easiest way to verify your 0,0,0 in world coordinates is to create a Workplane without any options (Workplane -> New). The origin of the workplane (you can show the axes in the show options), is the origin of the world coordinates.
