Materials:

ODA Visualize SDK render does not yet have its own materials in TurboCAD as LightWorks, TurboLux, Visualize or RedSDK.

The structure of ODA materials is very similar to the materials of other render engines, therefore added the ability to import materials from LightWorks, TurboLux, Visualize or RedSDK. Currently ODA render supports color, texture, transparency map, bump map, these parameters can be imported from LightWorks, TurboLux, Visualize or RedSDK materials.

If the options ‘LightWorks’, ‘TurboLux’ ‘Visualize’ and ‘RedSDK’ (from Program Setup\ODA Visualize page) are not set, then the default material (with graphic’s color) will be used. If the options are set, then the material that has the texture will be used.

Note: RedSDK materials can be used even if the plugin is not installed, but editing of these materials is available only if the Native Draw mode is RedSDK.

Regeneration:

When changing the view (zoom, rotation), primitives can change automatically or by pressing a key F5 (Menu View\Redraw or View\Regen) Drawing speed may slow down when auto-regenerate is enabled.

The user can specify which types of primitives will be updated automatically when the view changes.

Controls the display of TurboCAD warning messages. If you received a warning message with the "Don’t show this message again" checkbox, the warning message will appear in this table. Use the Show column to show or hide messages.UI enhancements of the Warning dialogs page Show/hide list columns. Right click on the header of the list to open the local menu. This makes it possible to show/hide list columns. NOTE: The first three columns are always visible.

Setting the value in the ‘Default’ and ‘Log’ columns Left clicking in a cell in the ‘Default’ or ‘Log’ column will cause a drop-down, combo box to appear, thereby allowing you to change the setting of that cell.

.

Sorting Columns in the appropriate order Columns can be sorted in two ways:

• Via left click at the header of the appropriate column
• Via local menu command. This local menu can be called via a right click within the list.

For the Time Column, the default sets the time in ascending order.

Filtering the contents of the list The ability to filter the contents of the list is available via the local menu. This local menu can be called via a right click within the list The filtering commands are:

• Show diagnostic – in addition to displaying normal content, the list also shows diagnostic messages. FALSE by default.
• Show fixed visibility – in addition to the normal content of the list also show messages for which the ‘Show’ state cannot be changed. FALSE by default.
• Show only appeared – Show only those warnings which have already appeared. If this option TRUE the content of the list is equal to the contents of this list in the all previous TurboCAD versions. TRUE by default.

Changing Multiple ‘Log’ or "show’ Settings Since the cells in the ‘Log’ column can have only two values (‘Yes’ and ‘No’), it is convenient to change the value for the multiple selected cells (it is also possible to do this with the ‘Show’ column). This is possible through the local menu. For Log: Simply use Click and SHIFT to select the cells, then open the local menu and select the appropriate yes or no option. For Show Simply use Click and SHIFT to select the cells, check or uncheck the option box.

Confirm replace Warning Message

If you tick the checkbox program will remember the last selected option and will not show the dialog again.

This dialog could be enabled again through Warning dialogs in Options.

Native Draw

Default UI Menu: Options/Program Setup/Native Draw

Ribbon UI Menu:

The Native Draw dialog allows you to specify which display/drawing engine will be used. you can select between standard GDI and Redsdk. GDI uses standard Windows CPU based drawing technology and CPU based OpenGL hardware acceleration. Redsdk is an OpenGL accelerated drawing engine that can substantially accelerate the speed at which entities are drawn.

GDI Options

Flicker Free Draw: When this option is turned on the redrawing of entities is made smoother, however, this can marginally slow down zooming and panning of drawings.

Redsdk Options

Hardware: Creates an anti-aliasing effect on 2D graphics elements. The values available are: Off, 1x, 2x, 4x, 8x, 16x. Turning this on will make the display smoother, but lowers the performance. Vertical Synchronization: Makes the display looking better, while moving, however it may higher memory usage. Text Smoothing: Turning this on will make the display of text smoother, but lowers the performance. Engine:

• Wireframe – Sets the engine anti-aliasing in Wireframe mode. Range – [1-5]. By default – 1. Enabled if Redsdk is On.
• Hidden Lines – Sets the engine anti-aliasing in Hidden Line mode. Range – [1-5]. By default – 2. Enabled – if Redsdk is On.
• Draft – Sets the engine anti-aliasing in Draft Render mode. Range – [1-5]. By default – 2.

Show Video System Info: Pressing this button will display the current video card setup on your computer. If your current driver for the video card is not the optimal driver for Redsdk you will be prompted to download the correct driver via a link within the window. If you do not download the optimal Redsdk will use a default driver.

Regeneration

To optimize performance Redsdk will delay the regeneration of some drawn elements during movements such as panning or zooming. Regeneration Mode: You can specify that regeneration is Manual, or automatic. If set to manual all delayed elements will not be regenerated until you press F5 or select Regen or Redraw from the menu. The Advanced settings for Regeneration allow you to specify which items are optimized and which are not. Image cache after: Specifies the size (in MB) after which rendered images will be cached. Advanced: Settings for Regeneration allow you to specify which items are optimized and which are not.

Miscellaneous

Display FPS: If this option is on a display appears in the upper right corner of the drawing space. This display tracks the Frame Per Second to indicate the speed of the Redsdk drawing engine. Delay Surface Load: Delays the loading of surfaces and objects until rendering to optimize memory usage. Caching of Model Space: Store the contents of the model space in the cache to optimize presentation. Disable GDI/RedSDK quick switching (recommended): When checked, the program will be forced to restart when switching between RedSDK and GDI (either direction). This is the recommended setting. If unchecked, you can switch without restarting, but minor display problems, etc. have occurred when doing so. Show Normals: When on this option causes Normals to be displayed on all 3D and Surface objects.

Note: Redsdk is dependant upon video cards which support OpenGL acceleration, and the features of that card. If you do not have an OpenGL video card you will not be able to use Redsdk. Recommended: Switching between GDI mode and Redsdk will require a restart of TurboCAD. Note: Redsdk conflicts with GDI’s native support for OpenGL hardware acceleration If you switch to Redsdk you will be prompted to allow TurboCAD to turn native OpenGL hardware acceleration off. With Redsdk turned on the Camera Properties "Renderable objects" is always disabled, "Suppress Hidden Line" is always enabled for all pages except the Wireframe page in Camera Properties Dialog.

Show Normals

The Show Normals setting is found under Program Setup/Native Draw. It is Off by default. The visualization of the normals makes it easier to estimate the smoothness and orientation of the 3D objects and to find artifacts/defects on those objects.

When this option is On the normals are drawn in red color at the vertices of the 3D objects.

Normals are drawn in blue at the center of facets and show the direction each facet is facing. The direction of each normal is determined by the path that the edges of each facet take as they wind around the face. The calculation uses the right-hand rule to determine the normal. The size of the normals is approximately 1/10 the size of the surface bounding sphere’s radius (the smallest sphere that will enclose the object). In other words, the size of the normal is directly proportional to the size of the object. The direction of the normals take into account the option Reversed Normals which is found in the 3D properties dialog of each object.

The base polygon of the normals are displayed takes into account the option Double Sided which is found in the 3D properties dialog of each object. Double-Sided objects show a double polygon. Normals for Double and Single sided primitives

Render Manager Options

Default UI Menu: Options/Program Setup/Render Manager

Ribbon UI Menu:

General

You can specify how the Render Manager is displayed by selecting either Classic or Palette-Like

Classic

• Variable sized preview.
• Tree can be hidden.
• Each category of components is displayed on separate tabs.

Palette-like

• Fixed square preview area (240×240)
• The tree cannot be hidden.
• While resizing the dialog, only the tree’s height, and the properties area size change.
• All properties of the main shader are shown on one page. Components of sub shaders are shown on separate pages.

The Palette-like option is always used when the Render manager is accessed from object properties.

Palettle-like	Classic
img	img

Low Level: Loads the minimal set of components – Active components ‐ Active components as well as those for the components in only the current type’s ﴾Material, Luminance, Environment or Render Style﴿ category. Medium Level: Loads a subset of components ‐ Active components as well as all categories for only the current Material, Luminance, Environment or Render Style type. High Level: Loads a full set of components ‐ All Active components as well as all types and categories.

How these function:

	Low	Medium	High
Called from application menu	Load only one shader set type (for ex. only materials)	Load all of one shaders set type (for ex. only materials)	Load all shaders sets of all types
Called from palette – selection exists	Equal to the "Single Entrance"	Load all of one shaders set type (for ex. only materials)	Load all shaders sets of all types
Called from palette – no selection	Load only one category	Load all of one shaders set type (for ex. only materials)	Load all shaders sets of all types

The Filter options in the respective palettes (Materials, Luminances etc.) will further control what will be loaded into the Render manager. As follows:

	Show Only Active drawing shader manager	Show all open Drawing Shaders managers	Show Application Shaders manager
Called from application menu	No	No	Yes
Called from palette	Yes	Yes (if "Show all drawings" is checked)	Yes (if "Show all drawings" is checked)

Choosing the Render Engine for loading in Render Manager

	RedSDK	LightWorks	Both
Called from application menu	Yes (if "Edit RedSDK…" was pressed)	Yes (if "Edit LightWorks…" was pressed)	No
Called from palette	Yes (if "RW" filtration button is pressed)	Yes (if "LW" filtration button is pressed)	Yes (if "All" filtration button is pressed)

Advanced Preferences

Default UI Menu: Options/Program Setup/Advanced Preferences

Ribbon UI Menu:

Advanced options for program control.

3D Boolean operations

Transfer material from operand on its facet: When checked, material from one object is transferred onto the other during a 3D Boolean operation (3D add, 3D subtract, etc.). When unchecked, the materials are not affected on either object.

Shader Sets

Copy shaders set to the application database: Sometimes it will be desirable to copy shaders from a drawing into the Application Shaders Manager. To resolve this issue there is an option on the ‘Preferences’ page. By default, this option is off. When this option is active when a file is opened all shaders sets will not only be added to the Model Shaders manager but also will be copied to the Application Shaders Manager. It is a not advisable to keep this option always active because if it is the Application Shaders Manager will gradually turn into a "trash bin". So the best way to use this option is to turn it on before opening the desired file and then turn it off again. Shared shaders set: This option defines the scheme of work with the render attributes (material, luminance, environment, render style). By default, it is off. Note: After changing this option it is necessary to restart TurboCAD.

Namely, the changing of a shader attribute in one drawing leads to the changing in all drawings and in the application database. Also, the local menus in the palettes and in the Render Manager for that attribute are changed. For example in the local menu of the materials palette the two items are removed (marked by green):

In the Render Manager, the local menu for the material from the drawing will be absent.

Miscellaneous settings

Nudge Step: Sets the distance that a nudge will move an object. Values are specified in Pixels.

Zoom factor: Controls how much you zoom in or out of the drawing when you use View / Zoom In or Zoom Out. The default zoom step setting is 2, meaning that zooming in doubles the size. See Zoom In and Zoom Out. Zoom In/Out Centralize: When this feature is On (default), rolling the mouse wheel will zoom in/out and centralize the view & cursor at the center of the drawing area. When this is Off, rolling the wheel will zoom in/out at the location of the cursor. Fixed relative origin: If checked, the relative origin will be fixed while in relative or polar coordinates. If you need to relocate the origin, it must be done manually. See Relative Coordinates and Polar Coordinates. Geometric select edit: If checked, objects will be selected by their geometric extents, rather than their cosmetic extents. This permits geometrically accurate scaling of objects like double lines and lines that have nonzero width. See Geometric and Cosmetic Select Modes?. Apply general property changes to all tools presets: Enables the Property toolbar to change all styles for all tools.

Intelligent Scale

Hatch: When a hatch is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom. Text: When a text is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom. Dimension: When a dimension is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom. Custom Coefficient: This is a scaling multiple that is applied to the intelligent scaling. For example, 2 would double the size whereas 0.5 would halve the size.

Draw by Layer

Options| Advanced Preferences

The Draw by Layer functionality is activated by selecting the Apply general property changes to all tool presets check box. This affects how tools relate to general properties such as Layer, Line Color, Line Width, Line Pattern etc. When active, changing any of those properties, while using a tool, will change that property for all tools in the same way. When inactive the application will behave in its traditional manner. This means that the layer setting for other tools will be unaffected, and changes to other tool properties, like Line Color, will only affect related tools. For example, changing the color of the Line tool affects the color of all line tools.
