Pipe Symbol Display - Jason this question is for you

[Anonymous]

Is there a way to show piping symbols like valves, turn ups, etc. at a
constant size in paperspace when drawing piping single line? As far as I can
tell the symbols are sized solely according to pipe size. In normal
drafting, symbols such as these would be inserted according to dimscale. Due
to my not knowing how to make this work for me I am unable to use the piping
aspect of BS3, unless of course the piping is large enough that I need to
show it double line. Any help would be greatly appreciated.

jason who??

Is there a way... Kinda. It's not a good way, but it might work ???

Let's take things one at a time...

Piping. I'm assuming that you want the "ticks" for the piping to be the same
size on all of the pipes all of the time. There are a couple special secret
commands that will let you do this (but they are slow).
AecbPipeFittingOverride
AecbPipeOverride

What these will do (one to a fitting and the other to a pipe segment) is
allow you to draw, say 1/2" pipe, but make the tick marks (assuming flanged
pipe here, I know you don't really use for 1/2" but the demonstration goes
better) look like 6" pipe (or whatever size).

The way that they work is by "copying" the annotation from one entity to
another, so you could draw you 1/2" pipe and then draw 6" pipe and use the
AecbPipeOverride command to copy the ticks from the 6" pipe to the 1/2"
pipe. Do the same thing for fittings.

Valves are a bit harder. To get this to work you are going to need to
completely hack the valve into pieces.

I have my drawing set up using schematic view for MvParts so my valves are
"schematic" looking. I can take the valve that I like the display of (size
and all) and explode it (make a copy first), then explode it again. Now I
should have "Simple" linework. I can make a block out of that (call it
my_schematic_valve_display). No for each other size valve I have in the
drawing I can right click it, go to Edit MvPart Style -> views tab and
change the schematic view from whatever it is set to to use
my_schematic_valve_display and click OK. Now I have to clean up the pipe
around the valve because it doesn't look right, but the valve is the right
size...

Rise Drops... Rise drops are style based. If you go into style manager and
look at the rise drop styles you'll see that you can adjust the scale of
them to use annotation, or provide a fixed scale. If you do this, you may,
however run into some issues with the piping around the rise drops not
cleaning up correctly.

Like I said, it's not a good way??

So basically the easiest way to deal with this is to draw all of the piping at the same size, say 4", because that's the way it looks best to me. I lose any functionality that comes with the pipe actually sized in the drawing, but as mentioned, the finished drawing looks correct. As I recall, S8 had an option to draw either to a fixed scale or to actual size. It's too bad that was taken away.

Hi Steve -

I can't really say that as that would completely conflict with the building
information model concept. You would need to draw all of your piping
purposely wrong!!!(G). While the building information model is important I
also understand that you get paid for CD's rather than models (at least
today(G))

I have heard of some users doing this, but they then need to create a number
of label styles and manually apply them as the logic behind the labels is
"fake", so it becomes hard to keep up with.

Schematic piping is capable of this now, as the "ticks" are based on the
annotation scale rather than the "size" of the objects. Schematic piping
doesn't work to well with interference detection though???

Hi Jason.

I'm happy to hear that you understand that it is the printed plan that is important. As I learn the new program, I keep getting the feeling that the model has become more important than the appearance of the plans.

As for creating label styles and trying to keep track, don't over complicate it. I can still use system labels for the pipe. And I would simply use text to indicate size, the way I've always done. Besides, the size label style is kind of a pain to use. We don't put our sizes directly on the pipes, we offset them and leader to the pipe. Getting the text to line up neatly and moving the text and leader have to be done separately.

I'm tempted to use the schematic piping, but it doesn't (or I haven't figured out how to) draw elbows as I go. I can insert elbows, but not once the corner is drawn. I also haven't figured out how to make 1-line piping break at crossings. As for interference detection, I don't get that with the plumbing systems anyway. It's tempting to either just use schematic piping or plumbing piping in place of the Piping system. It worked for us in S8. Seems like a waste of a whole module we paid for though.
