Step File Export

Step File Export

Hello,
I am struggling to get an assembly to export as a step file.. I know I need
to customise the layers to get rid of the skeleton and copy geometry
information from the saved copy. I don't understand the UI, though. I have
the choice between 'Ignore' and 'Skip' for each layer. What do these choices
mean? What am I ignoring, skipping, or otherwise? I want a button that says
'Don't export this layer'. I expect one of the choices means exactly that,
but which one? I have tried to do the systematic thing, click one, save it,
see what happens, click the next one, etc. but life is too short. It takes
an age to process each one, even crashing Pro/E sometimes.
I look forward to your advice.

Thanks,

I've not messed with layers on STEP exports, but I've had luck simply
clicking 'Solids' in the options dialog and unclicking 'Shells'. That
seems to prevent the export of any untrimmed construction surfaces that
may be layered off.



As for eliminating the skeleton, I'd try creating a simplified rep that
excludes it, verifying that it wasn't in memory and exporting the rep.

This is exactly what i do in this case..... 🙂 🙂

Thanks, chaps,

It solved the problem.

Let face it, 3D models drive the prototype process and production
tooling. In our company, Quality and some purchased parts still require
drawings. Drawings are expensive, time consuming, and prone to errors.

Is anyone making lightweight 3D PDF documents with just the critical
dimensions? Are you using 3rd party software? What are they?

I think this is the way we will go, instead of buying a laser scanner
for Quality to check parts.

Hopefully this will trigger a Friday rant. Thanks.

You say drawings are expensive and error prone. If this is true what do you use for QC to check against. The prints are generated from
the same cad program telling me that the program is flawed or someone isn't watching what they are doing.
A device like the Faro Arm is only as good as the program driving it so if your cad dwg is bad your results are bad. Garbage in garbage out.

We went with a transition approach in which we still have a 2D drawing but we save labor by leaving off most of the dimensions. Eventually the info that we include on this drawing could be placed in the 3D model on annotation planes. Most of the following will still apply when we stop using 2D drawings altogether:

We've defined what we call a Partially Defined Drawing (PDD) which is a drawing that has been simplified in that it does not contain a complete set of dimensions. For complete product definition the dimensional information is queried from the model geometry contained in the CAD digital data file. By definition a PDD is a drawing in which basic dimensions aren't shown and are to be queried from the Design Model (CAD digital file). All other dimensions, tolerances, notes, etc... are shown as on a fully defined drawing.

A PDD piece part's tolerances, by design, are predominantly defined by GD&T. This enables the majority of its dimensions, were they present, to be basic.

A key element of a PDD is the "Default Profile" - a relatively loose, unless-otherwise-specified, GD&T profile tolerance that applies to all features that do not have their tolerance explicitly defined. The Default Profile appears on the face of the drawing in one of the drawing views and is designated by use of the annotation "ALL OVER UNLESS OTHERWISE SPECIFIED".

The second half of this initiative was inspection

We require suppliers to have:

Digital inspection software. Inspection hardware (e.g. CMM) that is controlled by the digital inspection software. Software and hardware configured to utilize the Design Model in generating numerically controlled inspection routines. Standardized inspection report formats that can graphically present inspection data of all part features.

All features covered by the Default Profile callout are identified by ID codes that are automatically generated by the inspection software. The ID codes are displayed on a graphical representation (picture) of the Design Model such that it is clear which feature is associated with each ID code. These ID codes link features displayed in the graphical representation to actual measured inspection data. The inspection software also generates a section of the report in tabular format that includes the tolerance requirements, the actual measured deviations, and the out of tolerance data for each of the features as identified by the ID codes.

Regards,

Mike Foster
