Hi Bruce!
First, I have to admit I'm not familiar with Mac Brick CAD or even Mac.
But I downloaded the buffalo ldr file and analyzed it in Windows Notepad.
Step one: I changed the colour of the 3039.dat (Slope 45 2x2) to 47 (=Clear).
I noticed that the part is too far "back" in the head, so I changed the x value
from 140 to 144.
I don't know if there is a snap to grid option in Mac Brick CAD, and if you are
able to set the grid to a lower value, ie a higher resolution.
Step two: Change it back to colour 0 (=black) I haven't done this yet.
Next steps: Locate the other parts in wrong positions using whatever represents
Notepad in a Mac by changing the colour number. It is the second number of each
Type 1 line. Fine adjust the x, y, and z (3rd through 5th value)values by hand.
That's often a quicker method, I assure you that you'll learn quickly.
