How do I change the reference point in Eagle CAD for placing parts correctly? I'm using MARK but it did not set the new mark point as a reference. Is there a way to do this?

I just figured out how to do this. I'm using Eagle 6.5 fwiw.

MARK (C -7.5 -4.1);

Sets the origin to (-7.5 -4.1). The C says "left click". It also works if you type MARK and then actually left click with the mouse where you want the reference to be.

The manual and some docs on MIT's website are definitely worth a read here and there. For example: http://web.mit.edu/xavid/arch/i386_rhel4/help/25.htm

To set the origin back to the natural origin, you just type MARK;

You have to group and move all components. However, I would not recommend moving the componets with a mouse, as the selected grid might not fit.

Instead, use the command move (>0 0) (dX dY) to move the group a specific distance.

Example: move (>0 0) (-10 0), to move the group 10mil to the left (if the grid unit is set to mil).

  • \$\begingroup\$ @vicatcu The question is aboout "placing parts correctly". \$\endgroup\$ – sergej Aug 18 '15 at 20:12
  • \$\begingroup\$ I see what you mean... I'll retract the down vote. It's just disconnected with the question title. \$\endgroup\$ – vicatcu Aug 18 '15 at 20:49

The only way I can think of is to group everything and move the whole group. Make sure all the layers are displayed first.
