Multiprint may run slower if you have many flattened drawings or very detailed images and SketchUp models.:
It's best to avoid flattening too many drawings in Multiprint. Only flatten drawings when it's absolutely necessary. One helpful tip is to cover parts of a drawing you don’t need to see by placing a white filled shape on top.
Another reason for slower performance can be very detailed SketchUp models. You can usually tell if a model is causing delays by checking its file size.
SketchUp Models can be found here: "c:/Mozaik/Product Libraries/*library name*/Products" folder.
Here, you can check the file sizes to spot any large models. It's a good idea to use models that are 1000 KB or smaller, with under 500 KB being ideal. Smaller models generally help improve performance.
If you're using models from the Mozaik *2018 libraries, they include special 2D versions designed for plan and elevation views. These _2d.skp models are optimized for better performance and graphics, are smaller in size, and can also display curved objects like toilets and faucets more effectively.
