General Settings

This page deals with the following settings:

Tolerant Modeling

This command is only available with the Generative Shape Design product.

Input parameters

  • Merging distance: default value defining the distance below which elements are to be joined, healed or extracted.
  • This option is available with the following commands: Join, Healing, Extract, and Multiple Extract.
 
  • Extract and multiple extract commands have a particular behavior: refer to the corresponding chapters to have further information.
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 Tolerant laydown. When activated, a fixed lay down tolerance of 0.1mm is applied.
  • Tolerant laydown is available with the following commands: Parallel Curve, Sweep, Multi-Sections Surface, Blend, Split (surface by curve), Curve Smooth, Fill and Extrapol.
  • This option is applicable only at feature creation. Therefore, if the option is not checked when creating the feature, checking it afterwards has no effect on the feature.
By default, this option is not selected.

Open the TolerantLaydown.CATPart document.
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 surface.

  3. Check Tolerant laydown.

  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 set to 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

Uncheck Axes visualization limited to the bounding box of the input to visualize an infinite axis in the 3D geometry.
By default this option is selected.

Option checked

Option unchecked

Groups

Check Integration of created features as group inputs 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 not selected.
  • 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, refer to Managing Groups.

Stacked Analysis

Check Stacked analysis default behavior set as temporary to automatically create a temporary analysis when checking connections between surfaces or curves.
By default this option is not selected.
This option is only available with the Offset command.
