Analyze curvature

This command allows to visualize the shape or faces curvature.

Creation stages / Use:

Click on the icon or choose the command Analysis > Analyze curvature... from the drop down menu.

Select the shape to analyze.
Choose the radius curvature mode among the following list:(see examples bellow).
- Mean Curvature Radius
- Gaussian Curvature Radius
- Absolute Curvature Radius
- Maximum Curvature Radius
- Minimum Curvature Radius
- Oriented Maximum Curvature Radius
- Oriented Minimum Curvature Radius
Validate with to display the result.

Click the icon on the top right of the graphic area to quit the analysis result.

Available Options:

Hide:

The box allows to hide selected entities during the use of the command, to be able to select other entities more easily, especially those who were behind.

Color palette:

The color palette allows to modify the color scale in order to adapt it to the part geometry and so be able to visualize more easily the small curvature radius variations.

The "-" or "+" under the color range allow to increase or reduce the curvature values range on the graduations.

By clicking on the small color square under the color palette, the color range can be either continuous or discrete.

Mean curvature radius analysis with discrete scale.

Mean curvature radius analysis with continuous scale.

	To get the curvature radius on a given point, you just need to move the mouse above this point on the part.

Available Curvature radius modes:

A white color indicates an exceeding beyond the upper value, a black color an exceeding below the lower value.

Mean Curvature Radius:

It results from the mean of the two main curvature radii.

Gaussian Curvature Radius:

It results from the product of the two main curvature radii. However, the numerical value displayed on the scale is the square root of the product (this allows to keep a numerical value with a reasonable size).

Absolute Curvature Radius:

Allows to visualize the curvature of a surface without taking in consideration if it is convex or concave.

This mode is useful to bring to light the planar areas of a shape.

Maximal Curvature Radius:

Displays the absolute values of the maximum curvature radius.

For example, it can be used to quickly get the radii of an imported part.

Minimal Curvature Radius:

Displays the absolute values of the minimum curvature radius.

Oriented Maximum Curvature Radius:

Displays the values of the maximum curvature radius.

Oriented Minimum Curvature Radius:

Displays the values of the minimum curvature radius.

This mode is useful for machining in order to know if the tool fits with the convex areas of the part.
