You can use the arrow cursor to move the loaded 3D drawing. First select the direction you wish to move them in. You can either move them on the X-Z plane or along the Y-axis. Either click on the Y-axis or on the X or Z-axis for the plane. The free axis is highlighted. If you have selected the X-Z plane, you can move the drawing in the direction of either the X or Z axis. Holding down the ALT key allows you to move the selected assemblies freely.

Click the contour of the drawing with the arrow cursor. Hold down the mouse button and move the mouse. The drawing migrates on the axis as you move the mouse. The distance is displayed in the window bar at the bottom. The drawing will appear in its new position when you release the mouse button.
