Scaling an assembly

[kpv20]

I have a large assembly with more than 1000 components created using ProEngineer Wildfire 3.0. I would like to scale down the full model by a scale of 1/50. I tried two methods the first one being the 'scale model' option which doesnt seem to do anything when I enter a scaling value. I also tried to do the scaling by using the 'units' option whereIsuccessively converted the lenght units from millimeter to inch and then back to millimeter without applying the conversion factor. This didnt work either.

Does anyone know a way to scale an assembly in ProEngineer Wildfire 3.0?

Many thanks

Physical Models are always maintained at a 1:1 ratio. If you are trying to scale the model down to 1/50 youwill have to create Custom Units where 1=0.02 so 1 of your units = 0.02 after the factor takes place.

I don't really understand what the initial question may or may not have been
here. So if I speak out of turn it is because I am misinformed.



It seems to me that the original question was something about scaling down a
model. I am not sure exactly what you are planning to do with the model and
I would like to make some recommendations.



In Pro/E it is best to create the model as a full-scale entity. This will
include any of the components, sub-assemblies, etc. Then, after you have
created this assembly, you can place it on your drawing. Keep in mind that
the model is NOT being scaled down. The view is being scaled in relation to
the model. I hope that this clarifies the point.

While I have never scaled an assembly all at once we do scale items while still in the Industrial Design stage, but that is by small percents. With large amounts of scaling on small parts you are likely to have sketcher failures. Be careful and why?

Maybe he's trying to make files for a scale physical model of something big via SLA or SLS, ie for a wind tunnel test or a presentation model.

There are real-world scenarios where a model needs to be scaled, and scale views on a drawing are irrelevent.

I also assumed that would be the case.

If so, I would try exporting the model and scaling the export.

Best practice? Don't AutoCAD Pro/E!

[mlocascio]

Yes, you do bring up a good point. There seems to be something lost in the
translation.

If it is the case that this is required for SLA, SLS.....The software
that processes the .STL file can scale the geometry easily. One other
issue that I see with trying to scale an assembly is that any assembly
contraints that use an offset probably will not scale.
