Graphics Zoom-fit on Each Import - When a file is opened, SpinFire Ultimate automatically pans and zooms to provide a close-up view of the document contents while still fitting the contents entirely within the Viewport. If the checkbox is cleared, the view will reflect the camera position of the original CAD file. Points Visible on Picking - Makes vertex points visible as red dots during any command that requires a vertex to be selected. Enable 3D Auto-Spinning - Causes a 3D model to spin continuously when rotated quickly. Enable Gradient Background - The screen background is specified as a gradient. Point Size - The size of a point in pixels. Point Glyph - The shape of the point. Values are Cross, Circle, Solid Circle, and Splat. Selection Mode - The default object selection mode. Values are Part and Surface. Colors Background, Highlight, Highlighted Edge, Selected Edge, Edge, Grid Line, Markup Line, Markup Arrow, Selectable Point, Profile Edge, Profile Face, Point, Ruler Background, and Ruler Text Color colors - Click the respective Color... button to choose a default color for scene elements. 
Selected Color Palette - From the drop-down menu, select a color palette for your scene. Also, you can create a new palette — or modify an existing one — by clicking the Define Color Palettes... button. 
Ignore .ACT3D and .3D Background Color and Gradient ValuesUse this setting to ignore the background color saved in the .ACT3D or .3D file. It will use the Background Color set here in the 3D Viewer settings instead. 
Bloom Also know as glow or light bloom. Bloom is used to reproduce the illusion of extremely bright light overwhelming the eye — the light in the bright background bleeds into the darker areas, such as a figure in a doorway. Strength -The brightness of the bloom. Values are 1 to 10. Blur - The degree to which the bloom bleeds into darker areas (i.e., edges are softened). Values are 1 to 8. Shape - Specifies the shape of the bloom. Values are Star or Radial. Simple Shadow Creates a shadow cast by the model. Resolution - Determines the sharpness and density of the shadow image. Values are 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 ppi. Blurring - The degree to which the shadow edges are blurred. Values are 2, 4, 8, 16, 32, 64, 128, 256. Ignore Transparency - If selected, any transparent parts of the object will cast a shadow.  
Shadow Map Depending on the light source, SpinFire Ultimate will determine whether or not a pixel is in shadow and store this information as a numerical value in a shadow map. The resulting shadows have jagged edges. In order to smooth the edges, random samples of values stored in the shadow map are averaged, which produces a shadow factor that can be used to smooth the border between light and shadow. Samples - The greater the number of samples, the smoother the shadow edges, but the scene will take longer to render. Values are 2, 4, 8, 16, 32, 64, 128, 256. Resolution - The accuracy of the shadow map is limited by its resolution. Greater resolution uses more memory and can take longer to generate. Values are 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288. View Dependence - When enabled, the view is scaled and refreshed with the camera, ensuring consistent visuals in 3D View. Jitter - When jitter is enabled, a randomizing function is applied to the process of determining where to take shadow map samples. Jitter may improve a scene visually by softening jagged shadow edges. Simple Reflection Creates a reflection of the model. Opacity - The degree of non-transparency. Blurring - The degree to which the reflection edges are blurred. Fading - An gradient effect causing the reflection to appear as though it fades into the background. Attenuation Near Distance - The distance between the light source and the model where the reflection begins to fade. Attenuation Far Distance - The distance between light source and the model where the reflection is completely faded. Rendering Graphics Driver - Select a graphics driver from the drop-down list. SpinFire Ultimate supports OpenGL, OpenGL 2, OpenGL 2 Mesa, and DirectX 11. Frame Rate Enabled - Use the Frame Rate field when checked. Frame Rate - The number of frames of an animation displayed every second. The higher the frame rate, the smoother the animation will appear, but processing power and system bandwidth requirements increase as well. Values are 0 to 30. Anti-Aliasing - By default, SpinFire Ultimate will smooth out any jagged diagonal or curved lines. Also known as dithering. Clear the checkbox to disable. Rendering Mode - Wireframe, Hidden Lines Removed, Triangle Mesh, Flat Shaded, Smooth Shaded, Smooth with Edges, Reflective, Metallic, Surface Analysis. Culling Enabled - Enables culling when set. Used with the Culling Level setting. Culling Level - This is the size in pixels which objects are drawn. Smaller the objects drawn with larger the culling levels may be reduced to not appearing on screen. Larger culling levels may improve drawing performance.
Default value: 20. Depth Peeling Enabled - Enables depth peeling when set. Used with the Depth Peeling Layers setting. Depth Peeling Layers - Indicates the number of layers of overlapping transparency used when drawing objects. The smaller the value, the better the performance.
Default value: 5. Static Model Enabled - Enable to boost performance with pan/zoom/rotate. Usage may negatively effect other functionality. Front Facing PMI - Enable to have PMI text always front facing despite flipping and rotating of the model. Front Rendered PMI - Enable for PMI to always be in front. Views and Viewports Display Grid - When enabled, Front, Back, Top, Bottom, Right, or Left standard views include a background grid. Camera Projection - Determines how objects are viewed. In perspective mode, grid lines converge to a vanishing point. This provides the illusion of depth in the viewport; objects farther away look smaller. In parallel mode, all the grid lines are parallel to each other, and identical objects look the same size, regardless of where they are in the view. Values are Perspective Mode, Parallel Mode. Projection - Determines the orthogonal projection method used when the model is displayed in 4 Viewport and 3+1 viewport modes. Values are 1st Angle (4 Viewport: Left , Top, front, isometric; 3+1 Viewport: Bottom, Front, Top, lg isometric) 3rd Angle (4 Viewport: Right, Bottom, Front, isometric; 3+1 Viewport: Top, Front, Bottom, lg isometric).

Show Note Information Panel - When enabled, the instructional dialog window(s) and the final dialgo window for notes appears. Lock Tool Enabled - When enabled, the "Lock tool" checkbox is checked for measurements and notes. A locking tools allows use of the measurement or note feature repeatedly without re-initializing it. Label Fonts and Colors Font - Click the Font name (default is Microsoft Sans Serif 12 pt) to select font, font style, size, effects, and color for markup and measurement labels. Background - Click the Color... button to select the background color for markup and measurement labels. 
Save ACT3D Specifies SpinFire Ultimate ACT3D file export characteristics. B-Rep Compression - Set the level of boundary representation (B-Rep) data compression. Values are: None, Low, Medium, High. Include B-Rep - When enabled, B-Rep information is preserved when file is saved. The B-Rep provides greater accuracy when measuring volumes and curved surfaces, but increases file size. Tessellation Compression - When enabled, tessellation is compressed when the file is saved, which results in a smaller file size (but accuracy is diminished). 3D Preview - When enabled, 3D preview data is included when the file is saved. Shortcut Toolbar Define Shortcut Toolbar - Add, edit, delete to the shortcut toolbar to increase personal productivity. Export and export features are available to share a shortcut toolbar configuration with colleagues or to yourself on a different system(s). 
Tree Management Load Surfaces on Demand - When enabled, surfaces on not loaded during the opening of a 3D model file. Surfaces are brought in on demand (i.e - the assembly tree is expanded to those areas). This is disabled by default. Display Tree Attribute Name - Fill this field with an atribute found in the CAD file. The attribute appears as a new column in the assembly tree of SpinFire Ultimate. The same information is seen in the Properties of a part but having the value appear in the assembly tree is far more convenient. Consider using this setting with the Attributes importer option. For example, an organization may work with CAD files where an attribute, "Revision", is required. Entering "Revision" in the Display Tree Attribute Name field cause the value(s) of the Material attribute from the CAD file to be displayed in the SpinFire Ultimate assembly tree as a column.
