Johnny is correct in using a different layer for the drawing and title block. Bring in the title block using the wizard. Hide the title block layer/s and do your drawing in a new layer, when finished, scale the drawing down to fit in the title block. The best way to do this is to enable the gripper tool and "Select all" (cmd-A) then use either yellow block on the gripper tool to scale down the drawing, if the block next to the arrow is not yellow then you are not in uniform scaling, uncheck the nonuniform setting in the gripper palette. This first scaling is just a seat of the pants guess but going from a floor plan to a title block will be a big change. Next turn on the title block layer, you should see it next to the origin point and it will be very small. Use the gripper arrows to move your drawing to the center of the title block. Use the + (plus) key to enlarge the title block and the gripper yellow block to scale the drawing as needed and use the gripper arrows to move the drawing as needed to keep it centered in the title block. The gripper tool size will also need to be changed as you change the scale, we have asked the developer to address this problem but for now, just select the size in the gripper palette to reset it.
