Question

Hoses/pipes with windchill

Hi all,

First of all, I talk about pipes/hoses of which I've made the part (file.prt) starting from the "pipe center line".

I see that when you use pipe mode linked with WC, every time you load an assembly with hoses, the program feels that the assembly are changed also if you have not touch anything, also because you have only opened the file.

ProE/WC asks you how proceed: check-out or modify the parts (the hoses).

Which is the right procedure to solve this issue?

Thanks

Bye

HI, Can I ask how you are making the end references for the pipes/hoses?

I try to do these as measured transforms it stops the assemblies from reading data each time you open if you have created external or circular refs.

If you have circular refs then you will always be looking to read data in and WC will see that as a change.

Hi,

I make two coordinate systems into the top assembly and I use those as reference for the in/outlet of the hose. All the references are within the top assembly and I haven't circular references.

Can you share a view of the model tree please?

The problem is caused from the regeneration for the mass property.

If I only regenerate the model nothing happens. but if I regenerate the model imposed the regeneration of the mass property the program feels that something is changed (even if nothing is changed...).

The next step is: how can I manage the file.prt of the hoses within whindchill?

Because if I duplicate an assembly the file.prt remains the same, but it changes only if I change the trajectory in the first assembly. So I have to make a new file2.prt.

The risk is to generate a chaos of external references...

No More has encountered the same problem?

There isn't a way to prevent the regeneration of the hoses?

What is the right way to manage them?

Any part that has a configuration that depends on where it is used is a tough PDM problem to resolve.

There are two ways I handle this.

On items that are simple I set the item to be flexible and then customize the assembled item using that flexibility. A typical example is a hinge - the opening angle is set to be flexible so that for each placement the hinge can be adapted. Windchill sees only one model and each assembly (or even multiple uses within the same assembly) can have a unique angle.

The limit to my patience is currently a motor with related capacitor which required the use of parameters to drive the location and orientation of a csys to locate and orient the capacitor remotely positioned from the motor. 6 degrees of freedom for the one component -> six parameters + six relations.

This becomes a problem when the amount of variation gets to be burdensome, so I would not use it to route a multi-branch electrical cable.

For more complex situations I create items that are of the form base-name_installed-assy. If there is more than one in a single assembly they would get a numeric suffix Therefore the item that has a unique configuration based on it's assembled location is named, in part, for that location. The file with just base-name is the undeformed/nominal geometry.

The Common name for all the variations can be the same and repeat regions can gather them to make a BOM with correct quantities.

As for regeneration - make sure the mass properties are calculated in the footer. I think if the mass properties relation happens first it is marked invalid when the external references are updated and is then recalculated. It's marking it invalid and then replacing the value that marks the part as modified.** When it's at the end it is simply calculated. Since nothing is marked as changed, the part isn't marked as modified.

**I have no access to source code - this is a description of what the software seems to do, not necessarily what the underlying process is.

Hello friends Do you know any software for linking 3d piping  to isometric drawing (or) generate isometric drawings  for piping's excluding "m4iso isometric for ptc".

Export to PCF is available out of the box.  Almost all isometric packages support *.PCF

thanks, jim
