I’m working on rotation steps, and I’m not seeing LPub do what I expect it to
do.
I have the following file:
1 2 0 0 0 1 0 0 0 1 0 0 0 1 3865.dat
0 ROTSTEP 0 0 0 ABS
1 4 -150 -24 70 1 0 0 0 1 0 0 0 1 3005.dat
0 ROTSTEP 0 0 0 REL

That should give me:
- A step with a front view
- A step with the default 3D angle.
But instead I get the following:
0 ROTSTEP 0 0 0 ABS (should be a head-on front view?)
|

0 ROTSTEP 0 0 0 REL (should MLCad’s default 3D angle, z=0 y=45 x=23,
right?)

Am I completely missing something here? My output is not oriented the same
way the pictures Jim posted in his tutorial were.
I am using LPub 4.0.0.1 with LDView 3.2.

Hi, Allen.
Here’s what I see when I open your example in LPub 4.0.0.1:
I’m not sure why the difference, but I’ll list some possible factors.
- Side effects of other LPub options, e.g. to hide PLI
- LDView version (I use a “4.0 Pre-Alpha” version from SourceForge/Travis)
- Assembly image cache - try clearing it (from the Tools menu) and clicking the Redraw button
A confession: I never use ROTSTEP ABS (I’m just in the habit of using REL), so
I’m not very familiar with its behavior. I rotate things relative to the default
view.
I probably misuse ROTSTEP, too (but I put it to good misuse). I usually put
ROTSTEPs immediately after STEP commands (at the top of the file, for the first
step) and before the parts I intend to rotate. So, my version of the file might
look like this:
0 ROTSTEP 0 0 0 ABS
1 2 0 0 0 1 0 0 0 1 0 0 0 1 3865.dat
0 STEP
0 ROTSTEP 0 0 0 REL
1 4 -150 -24 70 1 0 0 0 1 0 0 0 1 3005.dat

Or, in the case of LPub multi steps, I put the ROTSTEP immediately after the
multi step begin statement (which goes immediately after multi step end, which
goes immediately after the STEP...).
Hopefully someone else can STEP in and clarify. I’m afraid I use a lot of voodoo
to insert these commands.
Jim
