You can only move members in the Frame window.  Before moving a member, make sure that there are no members selected in the frame.

To move a member

§    Point to the member away from its ends and press the mouse button

§    Drag the member to its new position

§    Release the mouse button to fix the new position of the member

The slope and length of the member will remain constant as you move the member.  You can only move members in the two dimensional views.

Holding down the shift key while dragging will constrain movement vertically, horizontally or to 45 degrees.  The coordinates of the pointer will be displayed in the bottom left hand corner of the window as you drag.  If you have turned on the Grid option, the member will move in increments of the grid spacing as you move.

If you drag a joint on top of an existing joint, Multiframe will create a connection between the members that meet at the common point.
