Export STEP Without Certain Curves

[dgschaefer]

WF5, M140



I need to export an assy as a STEP file. I have a number of sketch
curves in my model that I don't want to export, but I have projected
curves that I want to export. How can I exclude certain curves yet
retain others?



I've played with the layer control with no luck. I'm not sure what
'skip' vs. 'ignore' means, but it doesn't seem to produce any
predictable results.

If this is time critical issue, two solutions that might work...

I believe suppressing the feature will ignore it in the conversion. If this is not an option, you may need to do some extra work:

1. Export the file and re-import the file and delete the extraneous data. Then again, export the file.

2. Export the file without the curves as file1 and one with only curves as file2. Import file2 and delete extra curves. Export again.

1 is obviously simpler, but 2 may provide additional freedom by importing the curves separately.

3. You could try editing the STEP file to remove the extra curves.

Maybe someone will have a better answer. This is how I would go about it.

Very simple. Three steps.


1.) Enable the config.pro option "intf_out_blanked_entities no".

2.) Add the items you don't want exported to a layer and hide it, or simply hide them in the model tree.

3.) Start the export (or save-as), and then in the options dialog be sure to pick "curves and datums" (or something like that).

Doing this will only send to the export file (STEP, DWG, DXF, etc.) what is visible on the screen. If something is hidden on a layer, or hidden in the model tree, it will NOT be in the export file.

P.S. If you are exporting to a PDF file, the config.pro option listed above does not apply. There is a different option in the PDF export settings that controls whether or not to follow layer settings.

Great suggestion, but it didn't work. What I have are a series of
sketched curves projected on a curved surface. I want to export the
projected ones, not the sketched. I have the layers set to that my
sketched curves are not shown and the projected are. I set the config
option as instructed and most all of the curves were not exported. A
few random curves were. Weird.

Doug,

The only way I have ever gotten this to work is by using a temp part.
1) Create a new "Temp" part.
2) Create "ext copy geom" features (may take more than one) to select the
exact quilts, and curves that you want to include.
3) Export the geometry of the Temp part.

Good Luck
