How to merge two shapefiles of different geometry types?
If you still want to work in QGIS then you can do it by importing the shapefiles to GRASS and then exporting them back out again to shapefile. This should convert them both to polygon geometry and the merge will work. Make sure the two layers are loaded into QGIS before you start. 1. Load the GRASS plugin and the toolbars.
Why is ArcMap not merging feature classes and shapefiles?
Search on Esri Community Submit to ArcGIS Ideas “001156: Failed on input OID ; could not write value ‘ ‘ to output field .” This error indicates ArcMap is unable to merge conflicting field types or field lengths from the selected feature classes or shapefiles to the new feature class.
How to merge feature classes with shape classes?
For more information, refer to ArcGIS Help: Modifying field properties. 1. Export the shapefiles to feature classes. 2. Delete the fields with conflicting values or length with the Delete Field tool. 3. Open the Merge tool, and select the exported feature classes as input datasets. 4. Set the output location and run the Merge tool.
Why do I get error 001156 when merging feature classes?
During the merging process, error ‘001156’ occurs when the feature classes or shapefiles that are selected for merging contain fields with conflicting field data types or lengths. For more information, please refer to ArcGIS Help: Understanding field properties, aliases, and table display options.
What happens when you combine features from different layers?
Union combines selected features into one new feature. Although the features may be from different layers, the layers must be of the same geometry type—either line or polygon. Union maintains the original features and their attributes—that is, the selected features are not deleted or edited during the Union operation.
How to ensure the same CRS for different geometry types?
In order to ensure the same Geometry type, export each layer with a specific geometry: Right-click on the layer, choose Save As… and select (say) Polygon under the Geometry type box: You may also want to ensure the same CRS for each exported layer.

How do I combine two features into one?
Click the Edit tool on the Editor toolbar. Click the features you want to combine into one. Click the Editor menu and click Union. Choose the target in which the new feature will be created. If you have feature templates for the layers in your map, click the Template button and click the template to use to create the new feature.
