I don't know why it looks like that, but using part 3209.dat works fine for me
for a basic 2x3 slope brick. Do you know what number you were using?

I had a look at the file and I see the head is a bit mixed up. MBC has a few
answers though. To adjust the movement increment the easiest way is with the
toolbar (if you cannot see the toolbar in the upper portion of the viewing
window, goto the "Window" menu and select "Show Toolbar")
On the toolbar you will see a pull down menu with "Fine", "Medium" and "Coarse",
this is the movement interval for the bricks, with this set to "Fine" the head
can be perfectly aligned with the arrow keys (NB the movement interval can be
further customised in "Preferences").
To make the job easier, with the mouse rotate the model to get the optimim
viewing angle (I'm sure you worked this out already).

To make instructions is easy, however the buffalo file in its raw format isn't
an instruction file. For instructions, you need the 'STEP' command to be present
in the source file. 'STEP' is an Ldraw metacommand used to signify an
instruction step break.
Inserting 'STEP' metacommands is easy: Simply select the last brick in the
instruction step, then click on "STEP" in the toolbar. This will insert a step
command into the source file. If you open the text drawer (Apple-T) you can see
the source files, and the results of your actions.
In reality the buffalo file isn't well designed to make into instructions (i.e.
the bricks aren't stored in the correct order). I'd recommend that you study
Christopher Masi's mini.ldr file (included with MBC) for how to make models
suitable for instructions and experimenting with the actual production of
instructions. You will note the copious use of the 'STEP' metacommand in the
source file.
To preview a model instruction sequence, select "Step Display" in the "Options"
menu, then double-click in the screen each time you want to advance to the next
step.
Hope this helps a bit

| Hi all, I finally gave Ldraw a try, primarily to help me make instructions (though in the future I'll probably use this in the design stage for larger models). Right now I am just using the simplest features on Mac Brick CAD v 2.3b1, on a Mac using (...) (20 years ago, 3-Jun-04, to lugnet.cad)
