TIP: You can open several models and print them all at the same time. Just
repeat the open model procedure for each model you want to add. See the
―Placing models on the build platform‖ section for more information.
Unloading the model: click the left mouse button on the model to select it,
and then click ―Unload‖ on the toolbar, or click the right mouse button while
over the model and a context menu will appear. Choose unload the model or
unload all models (if you have more than one file open and want to remove all
of them).
Saving the model: Choose the model, then click ―Save‖. The file is saved in
UP3 format and its size is 12%~18% of the original STL file. This is a
convenient format for users to archive or transfer files.
Note on STL files: For a model to print correctly, all the faces of the models
need to have their normal facing outwards. The Up software uses model colour
to indicate whether a model is OK or not. The default colour used by the
software when opening a model is a light grey/pink colour. If the normal are
facing the wrong way, then the model is coloured in red.
