Rasterised PDFs and Point Clouds

Hello,

I have point clouds attached to my models but not displayed.

When models are referenced into drawing (WITH POINT CLOUD NOT DISPLAYED) the print automatically rasterises.

The box to switch off rasterising is greyed out.

I repeat that the point clouds are not displayed and there is no requirement for rasterising.

Is this perhaps being caused by a setting somewhere ?

By the way, the option to print in black and white is also greyed out.

This is happening in AECOsim, V8i, and Descartes.

Any help gratefully received.
