Hi. Trying to orthogonalize some building outlines. It works as I want in the Preview window, but not in the output file. Example and relevent bit of model in pic attached. Any ideas? Johnnie

Johnnie,

This looks like a projection issue. Can you attach the shapefile?

Thanks, Sam

Hi Sam. Any thoughts? Cheers, Johnnie

Johnny,

The false northing for the output shapefile is 0, which is incorrect. It should have been -50000, same as the input shapefile. We will take a look why this is hapenning. For now, you can edit the prj file and correct this or delete the prj file of the output shapefile and copy, paste and rename the input prj as the output prj.

Cheers, Sam

Hiya,

I'm not sure the issue is due to projection. I changed the input to OSGB and it still outputs a jagged outline when compared to the preview; see attached doc with images.

Cheers,

Johnnie

We have found the issue to be related to Multithreading.

For now turn off multithreading for features processing by setting Feature Request Budget in preferences to zero.

Preferences -> Applications -> Spatial Modeler -> Feature Request Budget
