Scene¶

Scene display settings can be adjusted in the interface as shown in Figure 1.

Figure 1. Scene Tab Interface¶

Display the dragger (rotation, translation) of the objects in the scene

After checking, the draggable trackball and translation axes will be displayed respectively by clicking on the object in the scene. Please press and hold Ctrl and drag to perform translation or rotation of the object, as shown in Figure 2.

Figure 2. Draggers¶

Load Model, Create Model:

Load Model and Create Model are to load the built model or newly build a model. In Create Model, the type and dimensions of a new object can be set, as shown in Figure 3.

Figure 3. Create a New Model¶

Attention

After loading a new model, it may look larger than the scene. The reason is the unit has not been converted from meter to millimeter. To solve the issue, please double-click the model and scale the model by 0.001 in the model affine.

Copy and paste of scene model:

Right-click the model name press shortcuts Ctrl+C and Ctrl+V to copy and paste.

The child model is copied and pasted together with the parent model.

After copying, click on the blank space to cancel the selection, and the model can be pasted in the root directory.

The names of all model copies are concatenated with ‘-1’,’-2’,’-3’,’-4’, etc. on the back, and the number increases from the largest number in the exiting names of copies of the model.

Press Ctrl for multiple selections, Ctrl+Z to undo, Ctrl+Y to redo.

Transparency setting:

Check the box on the left of the model name to show or hide the model, and drag the horizontal bar on the right to adjust the transparency of the models in the simulation on the left, as shown in Figure 4.

Ground settings:

The height and style of the ground in the scene can be set, as shown in Figure 5.

View rotation method：

The view rotation method can be set as natural perspective or free perspective. Under both methods, the perspective can be adjusted by holding the left mouse button and dragging, and the line of sight is always towards the origin of the natural coordinate system, but with free perspective, the simulation can be rotated with the line of sight that passes the origin of the natural coordinate system as the axis.
