T-FLEX Parametric CAD. Fundamentals. 2D Design

Fundamentals. Two-Dimensional Design
“3D Input Device” Tab
T-FLEX CAD supports three-dimensional
multifunctional manipulators compatible with the
standards Spaceball and SpaceMouse (for example,
the products of 3Dconnexion, a Logitech
Company, http://www.logicad3d.com). The 3D
manipulators allow panning, spinning and zooming
objects in the 3D window.
Once such a device is attached, the “SB: Show
Toolbars” dialog box gains another tab, “3D
Input device”.
This tab is used for setting up 3D device working environment. The user can set up device operating options
in three modes: for working with 2D drawings, for working in the 3D model window, and for working in the
3D model window in the active workplane mode. Selection of a working mode to set up is done in the pulldown
list of the parameter “View mode”.

The user can change:
- Mapping of the device axes on those of the T-FLEX CAD global coordinate system; direction of
action (translation or rotation) along each axis; sensitivity of the device to impacts for each type of
input (the “Axes” group). The device sensitivity is adjusted by the appropriate sliders. The more a
slider shifted to the right the less impact is required on the device for translating/rotating the model
along this axis;
- The level of filtration from accidental device disturbance (the “Filtering” parameter). The slider
position defines the filtration coefficient in the range from 0 (all impacts handled) in the left-most
position to 100% (only strongest impacts are handled) in the right-most position.
With simultaneous impacts on several axes of the 3D device, the axis of the maximum impact is
determined by the system. This impact is considered primary and is handled always. Other impacts
are handled only when they exceed the product of the maximum impact and the filtration coefficient;
