How to make an assembled parts position permanent out of assembly file
How to make an assembled parts position permanent out of assembly file
(OP)
I'm sorry if the title doesn't make any sense. The explanation is as follows:
- Suppose we have a bunch of parts to be assembled.
- We add the parts to an assembly file and assemble them using mating relations (3d constraints)
- By using mates we change the postions and orientations of the parts in specific ways. So that, when we measure a part's position with respect to absolute cs in the assembly file, and then measure the same part's position in its part file or make the part 'displayed part' againg wrt absolute cs; we see that they are different.
- What I want is to set the part's original position to its assembled one. So that when I open the part in its part file separate from the assembly, I see that it rests in its assembled position wrt absolute cs. How do I do this in the assembly file?
Best regards

I look forward to better solutions from other members.

If you design the parts from with the WCS at absolute in the context of the assembly, then when you save the component it will be in the position of the assembly.
Yes, do the component position BEFORE creating the drawings.
A lot of extra work to move the components after they have been created, as sketches don't like being transformed.

However, the question is how to re-orient after part creation.
I also like hellbents solution of using the wcs to re-orient. Whatever method you use, it is not a quick and easy operation in regards to existing drawings.

"Then make the component your work part and do an "Edit->Transform""
Should read: Then make the component your DISPLAYED part and do an "Edit->Transform"

One of the other members here does a lot of casting work. You can see a general outline of his modelling practices donw near the bottom of the thread here: http://www

The question about why such a need...I am also in the aircraft industry (though fairly new). As ewh stated, everything (except parts used in multiple locations, such as hardware) is modelled at aircraft absolute coordinates and no mating relations are used. This is good so far, but what if I want to use an existing component in a new assembly? In this case that part was modelled corresponding its position and orientation in the original assembly. But in the new assembly that it will be used, its position and orientation will be different. What do we do in this case?
I tried Hellbent's solution. But using the assembly base part's wcs and then transform->reposition does not work for me. It seems reposition only changes position not orientation. So the part still needs orientation.
I also used importing parasolids to the part. ewh said "Translate EVERYTHING but the parasolid to the same orientation as the parasolid", but how can I do this easily?

You have just discovered why I don't like assembled condition for the components, multiple uses. Put the component at absolute WCS and then use mating conditions in your assemblies.
Our UG designers have 'grown up' with this rule, put our Pro/E users refuse to use it. The Pro/E users like to be able use automatic mates to put their assemblies together. They claim it saves them time. The warranty cost per machine on our Pro/E designed machines is 6-8 times the cost on our UG designed machines.
To actually do it, put the parasolid import body on a different layer, then select all except that layer, then translate/orientate.

Drkwing....I'm not understanding what not's working with the reposition. You say it's not "orienting"? That csys based reposition should be putting it to whatever orientation it's in at the upper assembly level. Once done though it may have to be "repositioned" in the assembly...depending on the method it was originally positioned with, i.e. mates or no mates.
Take care....
