I know about the panels curling, because they aren't truly square, but I
haven't had too much trouble with bricks. Hmmm.
The curl is definitly related to larger plates. I ended up with many small
(approx. 10x20 stud) sections on the Pilot House deck in an attempt to
reduce the curl, but there is still curling even in such small areas....
The files were no big problem. I do have the Hull (about 10,000 pieces), the
Car deck (about 12,000), the Passenger deck (about 7,000) and the Pilot
House deck (about 3,000) all as separate files. There is also the engine
(500 pcs. ea.), and other bits in files by themselves. MLCAD can (on my PC @
800MHz) rotate the files in 3D. The Car deck is the slowest, but not
unusable. I don't know where the limit is, yet. I know that it is unlimited
to dimensional size. I never ran into any "edges" in the drawing field.
The biggest problem I have had with MLCAD is the panning time. On this large
model, I found it easier to work with windows that showed the same plane,
but different areas of the model. This model is nearly identical at each end
(although there are a couple of significant differences) and when I was
adding a section of parts to one, I added them to the other.
Another difficulty with the program is "layering". It is extremely easy to
add parts nearly at random regards their position in space, but there is no
"tool" for re-ordering the part list into a "stacking" order. I spent hours
with my text editor and even a couple of sessions with Excel sorting the
entries into something I could use as instructions.
I am a strong advocate of MLCAD for planning and recording purposes. The
best feature is the report piece count.
