3D MAP unable export to shapefile and import

411114039 — Wed, 26 Mar 2025 08:22:33 GMT

When you want to export the file as a shapefile, after selecting the layer, when you want to select the attributes in the data, the attributes will not appear and you cannot select them, and you cannot export the file successfully.

When importing files, the autocad map 3d error report window will pop up, resulting in failure to import successfully.

I would like to ask you for a solution.

Thank you.

Hi @411114039

Can you provide more info? Can you upload images of your drawing? Or better yet upload your DWG?

Importing to shapefile can be tricky. Your post doesn’t mention the ‘type’ of drawing objects you’re trying to export. You have at least two issues.

Issue 1:

What type of drawing objects are you trying to export? Are they points? Or lines? Or polygons? You can only export one feature class, or object type, at a time because shapefiles can only contain one feature class, e.g., if your layer has contains both lines and polygons (two feature classes) then you can’t export ‘the layer’ in a single operation. You need to export that layer twice, once for lines then again for polygons.

Issue 2:

If you can’t select attributes during your export procedure then it sounds like your selected objects aren’t exportable to begin with. At a minimum you should be able to select the Properties and export them as attributes (the same properties that appear in the Properties Palette), e.g., object’s layer, object’s lineweight, the length or area. In addition to those properties you may also export any Object Data (OD) attached to the individual drawing objects. The OD, when properly selected, will populate the shapefile’s database file (dbf). If you can’t select any OD during export, then your drawing objects might not have OD in the first place.

For a fast solution to your issues, upload your DWG so an accurate diagnosis can be performed.

The MAPEXPORT command has 3 tabs: Selection, Data, and Options. On the Selection tab, pick points or lines or polygon. A shapefile may contain only one object type.

Then in Select objects to export section, it might be easier to select your objects manually (see red circle) rather than by selecting an entire Layer. Use your cursor to select manually.

After proper selection, number of objects that will be exported will shown in lower left corner.

You may now proceed to the Data tab to to complete your MapExport procedure.

Check if the layer has proper object data or Map 3D-linked attributes—sometimes, and make sure the data table is set up correctly before exporting.

Because of the fatal error, please give the AUDIT command a try. The file maybe corrupt.
