While Stripe doesn't support monthly donations, you can still become a sponsor! Simply make a one-time donation equivalent to 12 months of support, and you'll gain access to the corresponding sponsoring tier. It's an easy and flexible way to contribute.

If you are not sure or not able to commit to a regular donation, but still want to help the project, you can do a one-time donation, of any amount.

Choose freely the amount you wish to donate one time only.

You can support FreeCAD by sponsoring it as an individual or organization through various platforms. Sponsorship provides a steady income for developers, allowing the FPA to plan ahead and enabling greater investment in FreeCAD. To encourage sponsorship, we offer different tiers, and unless you choose to remain anonymous, your name or company logo will be featured on our website accordingly.

from 1 USD / 1 EUR per month. You will not have your name displayed here, but you will have helped the project a lot anyway. Together, normal sponsors maintain the project on its feet as much as the bigger sponsors.

from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.

from 100 USD / 100 EUR per month. Your name or company name is displayed on this page, with a link to your website, and a one-line description text.

from 200 USD / 200 EUR per month. Your name or company name and logo displayed on this page, with a link to your website and a custom description text. Companies that have helped FreeCAD early on also appear under Gold sponsors.

Instead of donating each month, you might find it more comfortable to make a one-time donation that, when divided by twelve, would give you right to enter a sponsoring tier. Don't hesitate to do so!

Choose freely the amount you wish to donate each month.

Please inform your forum name or twitter handle as a notein your transfer, or reach to us, so we can give you proper credits!

Description

The Curves SurfaceAnalysis tool creates visual analysis maps on selected shapes.

Different analysis modes applied to a sphere. Left to right: none, Zebra, Rainbow, Isophote

Usage

  1. Select one or more sub shapes.
  2. There are several ways to invoke the tool:
    • Press the Surface Analysis button.
    • Select the Surfaces → Surface Analysis option from the menu. Note that a wrong name, Title, is used in the menu.
  3. A SurfaceAnalysis object is created and a zebra texture is mapped on the selected objects.
  4. Optionally edit the values in the Property editor to choose a different mode and adjust the related properties (see Properties below).

Notes

  • The naming and the icon in the GUI seem to be preliminary...
  • The object in the Tree view is always set to Hidden, and space bar can only switch visibility on but not off. The DataVisibility property in the Property editor still works properly for this task.


Properties

See also: Property editor.

A SurfaceAnalysis object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

View

AnalysisMode

  • ViewDirection (Vector): Analysis Direction.
  • ViewFixed (Bool): Fix analysis direction to global coordinate system.
  • ViewMode (Enumeration): Analysis Mode.
    • Zebra (default): Applies a black and white pattern.
    • Rainbow: Applies a rainbow pattern.
    • Isophote: Applies a rainbow pattern but only shows stripes according to ViewIsoAngles and ViewIsoTolerance.
  • ViewShading (FloatConstraint): Amount of shading on the analysis overlay.

AnalysisOptions

  • ViewColor1 (Color): First color (Zebra, Rainbow, Isophote).
  • ViewColor2 (Color): Second color (Zebra, Rainbow, Isophote).
  • ViewIsoAngles (FloatList): Angles of isophote curves.
  • ViewIsoTolerance (Float): Angular tolerance of isophote curves.
  • ViewRainbowAngle1 (FloatConstraint): Start angle of the rainbow.
  • ViewRainbowAngle2 (FloatConstraint): End angle of the rainbow.
  • ViewStripesNumber (Integer): Number of stripes (Zebra, Rainbow).
  • ViewStripesRatio (FloatConstraint): Relative width of stripes (Zebra).
