Generative Shape Design & Optimize - Part 10 ppt

Generative Shape Design This page deals with the Generative Shape Design options: ● The General tab lets you define the tolerant modeling, axes visualization and groups options. ● The Work On Support tab lets you define the work on support and the work on support 3D options. 753 Page Generative Shape Design & Optimizer Version 5 Release 14 General Settings This page deals with the following settings: ● Tolerant Modeling ● Axes Visualization ● Groups ● Stacked Analysis Tolerant Modeling Input parameters ● Merging distance: default value defining the distance below which elements are to be joined or healed. This option is available with the following commands: Join and Healing. By default, this option is set to 0.001mm. ● Tolerant laydown: in case the lay down of an input guide on a surface fails, you can check the Tolerant laydown button. When activated, a fixed lay down tolerance of 0.1mm is applied. This option is available with the following commands: Parallel Curve, Sweep, Multi-Sections Surface, Blend, Split, Curve Smooth, Fill and Extrapol. By default, this option is unchecked. 754 Page Generative Shape Design & Optimizer Version 5 Release 14 Here is a scenario with the Sweep command. 1. Create a tolerant swept surface and define a Deviation from guide of 0.1 mm. In our scenario we created a swept surface using an implicit linear profile and the ''two limits'' sub- type. We created Curve.1 and Curve.2 as the guide curves. 2. Create a parallel curve of Curve.1 using the swept surface as the support. The creation of the parallel curve fails. An error message opens informing you that the guide curve does not lie on the swept 755 Page Generative Shape Design & Optimizer Version 5 Release 14 surface. 3. Check the Tolerant laydown option. 4. Perform step 2 again. The creation of the parallel curve is successful. It is advised not to use a wire that lies on the edge of the sweep when working with the Tolerant laydown option. Output parameters ● Choose the Continuity Type: ❍ None: deactivates the smoothing result ❍ Tangency: enhances the current continuity to tangent continuity ❍ Curvature: enhances the current continuity to curvature continuity This option is available with the following commands: Project and Parallel Curve. By default, the option is None. ● You can specify a Maximum deviation to set the allowed deviation between the initial element and the smoothed element by entering a value or using the spinners. By default, this option is set to 0.001mm. This option is available with the following commands: Project, Parallel Curve, Sweep, Multi-Sections Surface, and Curve Smooth. For the Sweep and Multi-Sections Surface commands, only the Deviation parameter can be defined from Tools -> Options (the Angular correction parameter cannot be defined here). The Deviation and Angular correction will be activated only if the smoothing type is set to Tangency or Curvature. Axes Visualization 756 Page Generative Shape Design & Optimizer Version 5 Release 14 Uncheck the Axes visualization limited to the bounding box of the input button to visualize an infinite axis in the 3D geometry. By default this option is checked. Option checked Option unchecked Groups Check the Integration of created features as group inputs option if you want each new feature to be included as an input in an existing group and remain visible in the specification tree. If you uncheck this option, created features will not included in the group and will be hidden in the group tree (expand the group to be able to see it). By default this option is unchecked. ● This option is only available when creating a new feature. ● It is only available for features accessible in the Generative Shape Design workbench. All other features will not be included in the group even if the option is checked. For further information, please refer to the Managing Groups chapter. Stacked Analysis Check the Stacked analysis default behavior set as temporary option to automatically create a temporary analysis when checking connections between surfaces or curves. By default this option is unchecked. This option is only available with the Offset command. 757 Page Generative Shape Design & Optimizer Version 5 Release 14 Working with a Support This page deals with the following settings: ● Work On Support ● Work On Support 3D Work On Support ● Define the First direction scale (H for horizontal), by setting Primary spacing and Graduations values. By default, this option is set to 100mm for primary spacing and 10 graduations. ● If you wish, you can define another scale for the Second direction scale (V for vertical), thus allowing distortions of the grid. Check the Allow distortions option to activate the Primary spacing and Graduations fields of the second direction. By default, this option is unchecked. Work On Support 3D 758 Page Generative Shape Design & Optimizer Version 5 Release 14 Grids definition Define the default values for the grids, by defining Labels names and Primary Spacing values for each direction. By default, the Labels are set to X, Y, and Z for the first, second and third directions, and the Primary Spacing is set to 100mm for all directions. Grids customization ● Define the Grid labels unit, that is the coefficient of division for all straight lines units. For example, the grid label unit is set to 1 and the X label for one line is set to 500. If you modify the grid label unit to 10, the X label will be 50. By default, this option is set to 1. ● Define the Automatic Scale Factor, that is the scale to be used when the grid becomes too small. The factor is comprised between 2 to 10. By default, this option is set to 10. ● Define the Maximum lines number to be displayed on the screen, from 70 up to 500 lines. By default, this option is set to 70. All these values will be used as the default values when creating a support. For further information, please refer to the Working With a Support and Working With a 3D Support chapters. 759 Page Generative Shape Design & Optimizer Version 5 Release 14 Glossary A affinity An operation in which an element is transformed by applying X, Y, Z affinity ratios with respect to a reference axis system. C child A status defining the hierarchical relation between a feature or element and another feature or element. constraint A geometric or dimension relation between two elements. E extrapolate An operation in which an element is extended a specified amount while respecting tangency or curvature conditions. Typically a surface boundary can be selected for in order to extrapolate the surface a specified length. extruded surface A surface that is obtained by extruding a profile along a specified direction. F feature A component of a part. fill surface A surface that is obtained by filling a closed boundary that is made up from a number of segments. fillet A curved surface of a constant or variable radius that is tangent to and joins two surfaces. Together these three surfaces form either an inner or outer corner. G guiding curve A curve, intersecting with a profile, and along which this profile is swept. See also spine. J join An operation in which adjacent curves or adjacent curves can be assembled to make up one element. M multi-section surface A surface that is obtained by sweeping one or more planar section curves along a spine, which may be automatically computed or user- defined. The surface can be made to follow one or more guide curves. 760 Page Generative Shape Design & Optimizer Version 5 Release 14 O offset surface A surface that is obtained by offsetting an existing surface a specified distance. P parent A status defining the hierarchical relation between a feature or element and another feature or element. part A 3D entity obtained by combining different features. It is the content of a CATPart document. part body A component of a part made of one or several features. profile An open or closed shape including arcs and lines. R revolution surface A surface that is obtained by revolving a profile around an axis. rotate An operation in which an element is rotated by a specified angle about an given axis. S scaling An operation that resizes an element to a percentage of its initial size. sketch A set of geometric elements created in the Sketcher workbench. For instance, a sketch may include a profile, construction lines and points. spine A curve which normal planes are used to position a profile when creating a surface (lofted or swept surface for example). The profile does not necessarily intersect with this spine. See also guiding curve. split An operation in which one element is cut by another element. swept surface A surface obtained by sweeping a profile in planes normal to a spine curve while taking other user-defined parameters (such as guide curves and reference elements) into account. symmetry An operation in which an element is transformed by means of a mirror symmetry with respect to a reference plane, line or point. T translate An operation in which an element is displaced a specified distance along a given direction. trim An operation in which two element cut each other mutually. W wireframe element Elements such as points, lines or curves that can be used to represent the outline of a 3D object. 761 Page Generative Shape Design & Optimizer Version 5 Release 14 Index Numerics 2D inertia measuring A activating elements Adaptive Sweep command adding volumes adding volumes Affinity command analysis porcupine curvature analyzing curvature curve connection draft parameterization surface connection anchor point sweep angles Apply Dress-Up command Apply Material command applying 762 Page Generative Shape Design & Optimizer Version 5 Release 14 [...]...
