Are you doing 3rd angle projection or 3D?
10 minutes is a lot less than it took me in Paint. I suppose once you’re
trained in AutoCAD, a lot of things are quick.
Could you post jpegs of the results?

Hi,
Yeah, I’m working in ACIS Solids, then exporting to STL, then from STL2DAT.
I’ll try to do a few more this weekend and post the results to the same
folder. Something to do between TO soundbytes, anyway.
Is the DAT file helpful at all, or do you just want the orthographic
views/renderings? The views and images are cake compared to futzing with
converting the 3D model to DAT!

Please don’t go to a lot of trouble on my account!
It’s just that I usually post jpegs or bitmaps
|
Please consider not posting bitmaps. They are very space intensive and take a
long time to load. Instead use a lossless compressed format like .gif if you
can. In my view jpegs are not as good for things like line drawings, they are
better for continuous tone photos.

of things to my Brickshelf,
since anyone can view them without any special software. I’m not seriously
into CAD!
If I had the facilities to actually make some of these parts, I might think
more seriously about CAD. I did download MLCAD, but have hardly used it yet
due to lack of time. If I did CAD I wouldn’t have time to build! You can
see from my Brickshelf that I major in trains and technic:
http://www.brickshelf.com/cgi-bin/gallery.cgi?m=mbellis My CAD expertise is
more developed in circuit diagrams (see technic mindstorms folder), but this
is 2D and very quick in Visio, now that I’ve drawn a few component symbols.
|
Would you consider sharing your Visio library occasionally? Just a zip would be
great. Visio is a great tool I think!
Thanks!

I only use bitmaps when they are smaller than the equivalent jpeg - ie they are
monochrome ones. This was the case for the parts I’ve drawn so far. I’ve used
jpegs for colour pictures up to now.
I did a test with the 4x4 round plate drawing:
monochrome bitmap is 34KB
jpeg is 66KB
png is 63KB but loses definition
gif is 13KB
In this case the jpeg is larger than the bitmap, which is why I posted the
bitmap. I haven’t yet investigated GIFs or PNGs, so perhaps you could tell me:
Is GIF the standard highest compression, lowest loss format? If so, why doesn’t
everyone use them? I’ve seen animation in GIFs - how do you do that?
What are PNGs used for, since they lose definition?
Are GIFs or PNGs any more vulnerable to viruses than jpegs or bitmaps?

I’m glad Visio is so quick, since I can draw some circuits in my 30 minute lunch
break, saving on needing Visio at home. I copy the drawing to Paint and save as
a jpeg, since Visio seems to have a problem with saving picture files. I only
use the internet at home, due to work policy. Posted pictures are still open to
doctoring, but give away a little less than the source files. Perhaps you would
like to develop your own style :-) Feel free to use a print of one of my
circuits as you design your component symbols though.
For a resistor I drew a 1x2 rectangle with no fill at 100% in Visio, then at
200% added leads the same length as the box to the centres of the ends of the
box. I then put a text box by the side for the value. I grouped the four items
and set the double-click action to “Open group in new window”, so that I can
copy the resistor and edit the resistance value rather than draw another one.
I did the same with capacitors and diodes, making them a similar size. I’ve
done other components as required, keeping the same proportions, but now have
transistors, op-amps, batteries, relay contacts, Lego 9V plugs and some logic
gates. Other components are just a box. I use a line with the end set to 10
(round blob) a lot, since every T-junction should have a blob. I keep one of
each component in a template file, which I copy to start a new diagram. When I
start a new one I just delete the components I know I won’t need. For posting
on Brickshelf I set the line weight to 9 so that the wires show up.
The results are here: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=97964
Hmmm.. I think the FUT should be to lugnet.cad!
