Hello Jackie, Thank you very much for you answer. I will try to do what you suggest. Indeed, I already guessed that the variable was ‘empty’ but it did not dawn on me why.

You are adding to a layer without a point style set on the given scale range How can you rectify this? If this is the correct layer definition you intend to add a point rule to, then you should assign a point style if vectorScaleRange.PointStyle is None. Where can you create a new point style? From the same place where you're creating point rules: The layer definition object itself. - Jackie You wrote: Hello Jackie, I ran into a problem trying your code. This Line does not seem to work: vectorScaleRange.PointStyle.AddRule(pointRule) Error when running the code: [cid:image001.png at 01DADDBD.2CF4D050<https://lists.osgeo.org/mailman/listinfo/mapguide-users>] I ran a dir() on the vectorScaleRange variable and it shows no AddRule. I will take a better look at the API documentation [cid:image002.png at 01DADDBD.2CF4D050<https://lists.osgeo.org/mailman/listinfo/mapguide-users>] Met vriendelijke groet, GISkit BV Bart Oostdam
