Projection error in clean, trim and normalize step #48

Testing the plugin in QGIS 3.10 I get this error:

Without auto detect UTM zone image

With auto detect UTM zone image

@FranklinJS there is probably a problem with the input data coordinate system. Are you using shapefiles?

Make a copy of your data then try using the Define shapefile projection tool from the vector general group in the processing toolbox. Set the CRS to the appropriate coordinate system of the input data. This will NOT reproject your data only re-create/update the coordinate system parameters.

Let me know if this fixes your problem.
