Flange set up

Standard an elbow is built up with 2 CP's and 1 RP. The position of the RP depends on what page of the manual you look at or what part of the provided library you depend your elbows on. It can be no RP, 1 RP coinciding with one of the CP's and 1 RP on the crossroads of the construction lines.

 

You can even come across elbows that are really special (see inclosed pic, look at the vector of the second CP)

Now, flanges are even worse because the amount of needed elements depends not only on the manual but also on what part you open and how much of the wizard you take at face value.

 

Traditionally it's sufficient to have one CP (were the pipe will connect) and one RP (= FOF)

Also it seems to be best to have an Axis of Rotation defined.

Advisable is to also have one mate reference. (However in some cases there are multiple ones on the default flanges, sometimes only 1, the reason is obscure)

I've learnt here in the group that it's best to have a vertical axis defined so as make sure that the bolt holes straddle the route.

 

Seeing that are library is still in the tweaking stages I thought to ask what's commonly used so that we can try to avoid some of the errors and problems.

What do you use?

What would you advise?

 

E.g.: I've read on a particular thread that someone mentions that they use 2 CP's + an RP (the cp's being located at the front and back of the part and the RP in between)

Does this have merit, are more people doing this? And how do you solve the issue of not being able to put a dimension on your route that actually is in relation to the FOF.

Because there must be a better way then having to manually adjust for the length of the flange or half the width of a valve.
