inserting parametric parts and then moving them

[Anonymous]

i have developed a cast iron combo fitting which can automatically insert
into a system as a tee or be inserted as a separate part.

i am trying to figure a way to insert the part at the intersection of the
main barrel and branch direction of the fitting. since it is a tee, there
are only 3 connectors allowed. is there a way to insert, grap and
manipulate using a point on the part which is not a connector?

i do not want to have to spend the time i now spend to move each fitting and
associative piping.

i haven't tried is but maybe i need to redo the part and use a cross with
one leg having a zero length which would give me a fourth connector at the
desired "insert" point.

Roger,

Why aren't you using the provided Plumbing 3d fittings? You could copy
the SCH40 PVC and rename to SVCI etc. I'm also using the piping catalog,
but with BS4, they provided some plumbing content. With their fittings you
have a 50/50 chance of them being the right direction. If it isn't, just
rotating 3d should work. I haven't used it extensively yet, since we are
too busy for allowing time to set up all the catalog sizes, but it should
work. I'm still using my MVParts for drainage that I made in release 1.

There are a few reasons i am not using the catalog from Autodesk (excluding
that it was installed for some reason under the duct_components - probably
my mistake....).

1. I want fittings such as the combo (wye and eighth bend) to be
automatically input on the run as i lay pipe (i don't believe this can be
done with Mvparts) - Autodesk's parametric combo does not work this way.

2. The fittings will not work for Cast Iron and would need to be redone.
The constraints and dimensions for PVC fittings do not work with Cast Iron.
Refer to the combo model fitting branch length and main barrel length as an
example. There are other fittings which will not work for the same reason.

3. There is no intersection point for main / branch such as the combo which
will allow placement on non-pipe linework or relocation to align without
having to guess or draw linework to find the intersection. I have since
tried redefining the combo as a cross fitting and place the fourth connector
0.00001" off the main near the intersection and it does work - Autodesk
needs to provide a "connector" or something which is can be used for single
fitting placement (as a default) when not inserted into a pipe run or for
when moving / streching an existing run. This would be a big help.

4. I haven't looked into how big the Autodesk files get when using the a lot
of the provided fittings but the Autodesk models are somewhat complex and
used multiple planes. The fittings models i have generated up to now use a
single plane - will they take up less memory? - time will tell.

I don't know why you can't put the AutoDesk wye and 1/8 bend in
automatically when you run the pipe. If you draw a run of pipe, then draw
the branch from that, and you don't have the tee defaulted, you can select
the type of fitting you want inserted. The only set back with the program
is that there is a 50/50 chance of it being right. As for wyes, Peter
posted that if you change the type from wye to tee, you may be able to get
them to auto insert too, I haven't gotten a chance to try that yet, but
don't see why it couldn't be done.

As far as dimensions and constraints of cast Iron and PVC, we don't lay
out our undgrd for pre-fab, so the little bit of difference in the pipe
fitting dimensions should not affect a project that much. If you really
wanted to get technical, the catalog could be modified so that it is right,
but that isn't something our company would view as necessary. The connector
styles can be changed to the type of fitting you want to use.

We have been using the MVParts for all our drainage since release one. I
can say now, that it makes for a larger dwg using the mvparts than if you
were to use the parts that are from the fitting catalog. We are anxious to
get into using the AutoDesk provided sanitary fittings, but our workload
hasn't provided us the opportunity, it isn't easy to make the switch because
we want everything to have a specific description, and only catalog sizes
available etc. I do know that once it is made we will find things a lot
more efficient.

These are just some of my own thoughts and preferences. I just think
that using the auto insert etc. will speed up productivity instead of always
having to go to the MVParts to add drainage fittings.

Mike/Roger -

You will need to change the type and toggle the autoinsert flag to make wyes
autoinsert.

There are cast iron DWV fittings in the catalog Plumbing Pipe US Imperial.
The upcoming extension delivers the same fittings in metric sizes...

I hope this helps!
