HI All,

I have prepared a workspace that allows the user to clip a LAS file and export it to LAS or DWG. I was thinking to use the GenericWriter to include the options for the user….but the transformer fails when trying to export as LAS. The reason for that is because I have included a PointCloudToPointCoercer right before the writer to make sure the points are written to DWG however the fme_point geometry isn’t allowed by the LAS format as requires point cloud geometry. Here is a visual screenshot of the workspace:

I have included (for now) an additional LAS writer that skips the PointCloudToPointCoercer and writes the LAS file as point cloud geometry…

How can I modify the User Parameters to allow the user to chose one writer (LAS) or the other (DWG)?

A Choice User Parameters and put a Tester or TestFilter before sending it to your Writers so based on what the user choose it will send it to the Format that he wants.

FME can do it, I'm having a beer! Cheers
