Screw insert in assembly

[marcofa]

To draw in Autocad many screw and bolt in an assembly I created a components ( Bolt + washer + washer + nut ) database to copy and paste . Different composition i.e. distance from bolt head and nut 10, 15, 20, 25, 30 mm was designed and stored.
In Catia v5 to insert in an assembly many bolts with washer and nut is very hard: bolt constrains + washer constrains + washer constrains + nut constrains.
If more than 200 screw are needed its CRAZY! or >:-<
There is a clever system to save time and energy?thumbsup]

Marco - Assembly Design - Re-use Pattern is the command you are looking for. This takes a pattern from a Catpart and applies it to assembly components.

I know reuse pattern, but hire is not the case.
I have CatProduct build by many parts fixed together by bolts and nuts. There is no pattern availables because different thread and lenght.
If I have 100 bolt 100 nut and 200 washer its a crazy work

You can create a component for each instance and copy and paste that component as many times as needed.

Sealz,

That will work for getting components into the tree but you'll still need to constrain them to each location. Mulitiple components in V5 are a PIA if there are no patterns to reference. Pro/E had the ability to place components by saving known references, like placement surface, and then varying the ones change would change, like the axis. I've yet to find a command like that in V5.

I'm not going to claim this is the correct way to do it, but here is one way, if you don't mind having your screws/washers/nuts modeled as one part body.

Make a new part with your screw, washers and nut, in one part body. If you are clever when you do this, you can model this such that everything relates back to one original sketch. Make this a positioned sketch, with a face and a center point.

Then, copy/paste this part body into another file in your assembly. You will get an error because the positioned sketch loses its face and centering point, but you can change sketch support and pick the face and center point where you want the screw. Then just change the length to suit the application.

It gets even more convenient if you use a design table to drive your screw/washer/nut part, then you can easily switch sizes before you copy/paste.

It takes a few extra clicks after copy/paste because you have to redefine your initial positioned sketch, but it may be easier than doing the assembly constraints? And this way you could actually keep all your screws/bolts/washers in one part file, if you desire. May be a good thing or it may be a bad thing.

I have used this method with well over 100 fasteners, with probably 30 or 35 differents sizes/lengths etc... (e.g. not patterns).

Thanks Albigger,
but is not very clear for me.

"If you are clever when you do this, you can model this such that everything relates back to one original sketch. Make this a positioned sketch, with a face and a center point." I suppose in this case I need to design again all the things and I cannot use existing catalogue! Can I make an assembly from catalogue parts and then transform it to Part? What seems "everything relates back to one original sketch"??

"Then, copy/paste this part body into another file in your assembly" What you means for "another file"?'

"And this way you could actually keep all your screws/bolts/washers in one part file, if you desire" All screw.... in only one Catpart??

"you can change sketch support and pick the face and center point where you want the screw. Then just change the length to suit the application. " I dont understand.

Can you make an example to connect enclosed parts with two screw+washer+nut with different lenght?

Thanks
