Inserting the External Drawing

Insert Menu > External Reference...

AllyCAD prompts "indicate xref insertion point" There are also options to select Xref, change angle and scale (x,y,z).


In this example the inserted drawing needs to be scaled down, as the title block is A0, and the drawing is A3, we specify a x and y scale of 0.35. (A0 841x1189, A3 297x420, 297/841 = 0.35, 420/1189 = 0.35)

The xref will will be unloaded.


If you want the xref to be part of the drawing, click on the Bind button. The xref will bound into the drawing.
