From Point

()

Keyboard: FROM

Use the From Point tool to set a temporary base point from which to offset point selection. The From Point tool can be used only while another active command is requesting a point.

Base point: Select where to place the temporary base point.

Base point <Offset>: Enter the offset distance from the base point, for example, (@8.5,0), where you want to locate the next point. Note that entering (8.5,0) places an absolute point from the UCS origin, not a relative point from the base point.

Continue with the original command.
