    Allegro dxf export. How to export height information? Reply

    I have seen a post stating that it's possible to export package height information with a dxf, but it doesn't appear to be working for me. I do have CDN_TYPE, SYMBOL_TYPE and REFDES but no other properties.

    Thanks

    Make sure you check Export Symbols as Blocks, then you should get what you need.

    I have tried exporting the symbols and padstacks as blocks. Still no height info.

     What is your mechanical package?  The EMN/IDF interface works really well.

    We use Pro-E and yes we have some experience with EMN/IDF, but I wanted to see the info in a dxf as well.

    As far as I know, DXF is a 2-d exchange.  IGES and Step are 3D.  That would explain why heights aren't being passed.

    The IDF interface is the way to go if you have Pro-E.  I've had better luck treating mounting holes as one-pin components.  But, its more reliable than DXF.

    DXF has been able to include the height for quite a while. I would check that you are running the latest hotfix for your version of the software and if it still fails then talk to Cadence / VAR directly. IDF and IDX is a great format when using Pro-E for 3D. Proe-E has a ecad_hint.map file that will swap your 3D blocks from the IDF to the actual 3D models.

    If you wish to export package heights, you should use IDF. The 2D DXF model offers no way to transfer a 'z' value for a polygon. With IDF, you can only transfer a single height and place bound per package. If your symbol is made up of multiple place bounds, Allegro combines them and outputs the largest height value. The newer IDX standard supports a symbol that contains multiple place height bounds but you will need to check if the consuming tool supports IDX.
