Customizing System
The “Scene rotation” group defines the modes of spinning the 3D scene by certain increments, as follows:
Using Arrows. Defines the angle in degrees of rotating the 3D scene per a keystroke when using the two
pairs of arrow keys, plus the third pair and .
Using Ctrl+Arrows. Defines a second spin-with-key mode for rotating the 3D scene by a different angle.
This is similar to the “Using Arrows” parameter, except is used in combination with the key.
Smooth rotation. This flag sets the smooth 3D scene rotation mode during reorientation to a standard
view. The input box on the right-hand side defines the reorientation duration in seconds.
Note that setting the mode of rotating the 3D scene with respect to the global axes (the command “3RS:
Rotate About Global/Local axis”) makes the 3D scene spin with respect to the axes of the world
coordinate system. Otherwise, the 3D scene will spin with respect to the axes of the screen coordinates.
Turn Workplane on Activation. If this flag is set, the 3D scene will be reoriented on calling the
“Activate Workplane” command so that the active workplane becomes parallel to the screen.
The “Regeneration” group of parameters defines the 3D model regeneration (recalculation) mode
parameters:
Automatic Regeneration. When this flag is set, the 3D model will be regenerated automatically after
making changes in the 2D model parameters (upon exiting the variables editor, changing construction line
positions, etc.). If the flag is cleared, then the automatic regeneration does not occur in such cases. To
recalculate the model, you would have to manually call the model recalculation command
“Tools|Regenerate” or .
Abort on error. This parameter defines the system reaction to errors occurring during the model
recalculation. When the flag is disabled, recalculation is not terminated upon encountering an error.
Messages about all errors occurred in the recalculation will be displayed in the diagnostics window. If the
flag is set, the 3D model recalculation process is terminated upon encountering the first error.
Don't Create Shading Mesh. The use of this flag allows speeding up the model recalculation in the
“Wireframe” mode. When working in the “Shading” or “Rendering” mode, the mesh is always created,
regardless of this parameter setting, according to the settings made in the command “ST: Set Model
Status” (“Customize|Status|3D”), and there is no speedup.
Limit Memory for Calculation of Projections, МB. This parameter enables to set the upper bound on the
size of the memory used upon recalculation of 2D projections. By default, the following limitation is set:
- For 32-bit operating system Microsoft Windows – 300 МB;
- Upon using 32-bit version of the T-FLEX CAD with Windows x64 – 1000МB;
- For 64-bit version of the T-FLEX CAD x64 with Windows x64 – no limitations.
Use Multithreading on Calculations. This flag activates the mechanism of multithreaded work with the
T-FLEX CAD on computers having multi-core processors or on multiprocessor systems. This enables to
increase the speed of regenerating the models. Multi-threaded data handling is used upon calculating
geometry of 3D operations, calculating finite-element meshes.
Create Explode Information for 3D Fragments Automatically. If set, the default explode parameters will
be assigned to 3D fragments upon assembling. These parameters are otherwise accessible on the
“Transformation” tab.
Don't Create Cosmetic Threads. When this option is activated, the cosmetic threads are not displayed in
3D models. This option has action only on the image created in the 3D window and does not affect 2D
projections and dimensions on the threaded surfaces.
