By default all selected files are merged into the 3D scene. If more than one file is selected, Sequence Animation may be enabled to produce a playback sequence, akin to Flip-Book Animation. If more than one file is selected and Layered is enabled, all files are shown at once, with a layer separation control added to the PDF file.
If Spin is enabled, the entire scene is rotated around a central axis, at an approximate Revolutions Per Minute (RPM) speed.
Animation and related settings may be defined using the simple menu, shown below.
If you load more than one input file, then Exploded, Layered, or Animation menus become available. These are not available for single input files. The Spin menu is always available.
No options selected (default)
If none of the above options are selected, all input files are merged into the same scene, always visible, sharing a coordinate system, without animation.
Exploded
The Exploded option shows the input files separated in space, in a general side-by-side layout. This can be helpful to compare two different variations of a model. No animation is shown. The positions of exploded objects can be specified by offset position, scale and rotation using the Interface Settings Common menu.
Layered
When Layered is selected, and multiple input files are in the same coordinate system, they will be shown co-existing in the same scene, with an offset applied defined by the three X,Y,Z offset vector values. In addition, a layer menu is added to the PDF, allowing the user to control layer visibility and offset multiplier along the defined axis. The layered mode must be enabled to add the Layer Control feature to the page using the controls option settings.
Sequence Animation
If Sequence Animation is selected, then each of the input files will be loaded one at a time, and shown in sequence making a small movie flip-book. A playback control for pause, play, stop, playback speed and single step is added to the PDF under the 3D view.
Progressive Animation
If the Progressive option is also enabled, then as the animation sequence progresses, each new input is added into the scene without hiding any previous input. In this way the scene slowly assembles until at the last step all input models are visible.
X, Y, Z type-in fields
The three floating point number fields define the X, Y, Z offset vector used to displace models when the Layered option is selected.
Spin Scene
If Spin Scene is selected, a very simple 360 degree continuous rotation is applied to the entire scene, where all objects are rotated around the scene center. The speed and axis are defined by the X, Y, Z vector. A small playback menu is added below the 3D view.
Rotations Per Minute (RPM)
The rotation rate, specified in rotations per minute may be set. Note, this is only approximate, the actual rate will depend on the model size, rendering speed of the computer display, etc.
