Possible to Reorientate rotation of SpinCentre of an existing assembly?

Possible to Reorientate rotation of SpinCentre of an existing assembly?

Possible to Reorientate rotation of SpinCentre of an existing assembly?

(OP)
Hi all, first post. :)

In my role, I create Technical illustrations based on exploded Creo assemblies.
Workflow is:
> Take Creo assembly and create an explode state the way I need it for the tech. Illustration.
> Export as STEP file
>Take into PCT Isodraw to convert to EPS vector file.
> EPS into Adobe Illustrator for annotation and tweaking.

The other day had an assembly which becasue of the way it was modelled, the Y-Axis was pointing down the length of the model rather than straight up?
This meant when I imported STEP file into Isodraw the model was exploded UP rather than OUT (in what should have been the Z-Axis).

In other software you can create a new 3 point co-ordinate system on the fly by clicking 3 points on the model, is there an equivalent way to do this in Creo?

Can I change rotation references of the Spincentre so that I can have Y-Axis pointing UP rather than along the Z?


Hope this makes sense, I've attached a screenshot of what I'm asking about.

Thanks. :)

RE: Possible to Reorientate rotation of SpinCentre of an existing assembly?

You can create a new CSYS from an existing one and apply rotations and translations as required. The is preferable because it won't be affected if parts change.

I don't recall a 3-point method, but you can also reference two axes/edges to create one from scratch. Creo will put up a dialog box that allows changing which direction corresponds with an axis and allow flipping the positive direction. If the edges/axes are changed the CSYS construction might fail, but that might not matter for your purposes.

that's great, thanks.

You said: "Creo will put up a dialog box that allows changing which direction corresponds with an axis and allow flipping the positive direction."?

How do I acces this dialogue box please?
(I'm an Inventor guy by trade, so still picking Creo up as I'm going along. :))

Thanks.

RE: Possible to Reorientate rotation of SpinCentre of an existing assembly?

It's part of the CSYS dialog where you pick the references.

Thanks very much.

Have worked out the dialogue box and made the references (this surface references Y etc...) but having an issue whereby the "OK" box is greyed out, so I cant finalise the new Co-ord system?


Almost there. :)

RE: Possible to Reorientate rotation of SpinCentre of an existing assembly?

That's why I first recommended creating a new one from an existing one. Since the only reference is a CSYS there aren't any choices that won't work.

Thanks again 3DDave.

I have tried that and cant get the new co-ordinate system to save...the "OK"buton to confirm it is greyed out.
New to Creo and finding this fundamental thing frustrating!

Is there a "create new co-ordinate system" tutorial anywhere...almost there but its still eluding me. :)


Thanks.

RE: Possible to Reorientate rotation of SpinCentre of an existing assembly?

Have you tried creating any new feature?
Have you tried creating a new CSYS in a new part?

I really can't guess why it's not available unless you don't have permission to make changes to the assembly. In that case, create a new assembly and place the current assembly as a component in the orientation you want.
