Insert Sample

Sample models may be imported from a 3D model file, or creating from primitives. Both options are detailed below.

Import a 3D model from file

The 3D model for a Sample may be imported from ASCII/binary STL files or Wavefront OBJ files. Click Insert > Sample > File and browse to the location of the 3D model and select it. The mesh will be cleaned (repeated vertices and faces with zero area will be removed) and the model will displayed in the graphics window.

Tip

STL files in ASCII format will take more time to load than binary files but performance after loading will not be affected.

Create a model from primitives

Simple models may be generated from primitives, e.g. cuboids, spheres, tubes, cone etc. Click Insert > Sample > primitives and select the desired primitive. Type in the required parameters for defining the primitive and click the Create button.

Tip

Use the button to quickly switch to another primitive.

Add another model

In some cases, a second model may be needed to properly approximate the sample or a holder. After adding the first sample, to add a second model simply follow the steps above for file or primitive, you will be asked if the new model should replace the current one or be combined with it.

Note

Combining models is only possible for mesh samples not volumes.

View model properties

In order to view the properties of the sample click View > Other Windows > Sample Properties.

For mesh samples- the memory (in mb), faces and vertices are displayed.

For volume samples- the memory (in mb), dimensions, voxel size, minimum intensity and maximum intensity are displayed.

Note

Use the Ctrl+Shift+I keyboard shortcut for quick access to the sample properties information.

Export a sample

The 3D model for a Sample can be exported from project file to a STL file. Click File > Export… > Sample in the main menu, navigate to the desired save location in the file dialog, enter a name for the file and press the Save button.
