Moi is not reading the polylines I think.

Hi Tim, there are quite a lot of different types of things that can be stored in a DXF file.

MoI's DXF import is only focused on 2D drafting type entities.
It can read these entity types from a DXF file:

LINE, CIRCLE, ARC, POINT, LWPOLYLINE, POLYLINE (LINE/ARC DATA), ELLIPSE, SPLINE, TEXT, MTEXT, DIMENSION, LEADER.

Your DXF file probably contains polygon mesh data in it either as "3DFACE" or "Polyface mesh" entities. MoI does not try to read those entities because MoI is not designed to work with polygon mesh type objects for modeling.

That's just my best guess though, it's difficult to know for sure just looking at screenshots. I would need to examine the file to know for sure. Please post the DXF file as an attachment or e-mail it to me at moi@moi3d.com


re:
> Is there an import function in Moi v 5 that will bring in all elements,

Sorry no there isn't. To be able to read every type of entity from DXF would require implementing every type of object that AutoCAD can represent.

Rhino is closer to doing that than MoI.

If you have a relatively light number of 3DFACE (polygon) elements you could open it in Rhino and use MeshToNurb command in Rhino to convert the polygon mesh data into NURBS surface data, then export that as a Rhino v5 .3dm file and that should then go in to MOI.

I’ve had similar issues with DXF files in Moi—sometimes certain elements just don’t show up. You might try re-exporting through Rhino first to clean the file.

Hi mike,

re:

If you run into this please send me the DXF file.

In this case it was due to a "vertices follow" flag that Leica was not setting on POLYLINE entities in the DXF file.

Without that flag set MOI would not read the vertices in. However, it's only on very old versions of the DXF spec that this flag was required.

Since at least AutoCAD 2010 the spec was changed to say it's not required.

So I've tuned up the MOI DXF reader so it will read the following vertex entities whether the flag was set or not and that fixes this import.

If you run into these issues please report them and (most importantly) send in the DXF file so I have an actual example to test with.

Thanks,
- Michael
