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!

PartDesign workbench icon PartDesign Workbench

Introduction

The PartDesign Workbench provides tools for modeling solid components. It is mostly focused on creating mechanical components that can be manufactured and assembled into a finished product. Nevertheless, the created solids can be used for any other purpose such as BIM modeling, finite element analysis, or machining and 3D printing.

The PartDesign Workbench uses a feature based methodology. A component is represented by the Body object container. The Body defines a local coordinate system and contains the cumulative features that define the component. Most features are based on parametric sketches and are either additive or subtractive. For example, the Pad tool adds the extruded sketch to the developing solid, the Pocket tool subtracts the extruded sketch. Each feature is cumulative and builds on the result of preceding features. It is also possible to use primitives (wiki-test2.php?gitpage=Cylinder, Sphere, etc.) as well as solids created outside the Body as features.

See the feature editing page for a more complete explanation of this process, and then see Creating a simple component with PartDesign to get started with creating solids.

The Part Workbench provides an alternative constructive solid geometry (CSG) methodology for building shapes. For a detailed discussion of the Part Workbench versus the Part Design Workbench see Part and Part Design.

Tools

The Part Design tools are all located in the Part Design menu and the PartDesign toolbar that appear when you load the Part Design workbench.

Part Design Helper tools

  • [Create body](wiki-test2.php?gitpage=PartDesign_Body): creates a [Body](wiki-test2.php?gitpage=Body) object in the active document and makes it active.
  • Create Sketch:

- Create sketch: creates a new sketch on a selected face or plane. If no face is selected while this tool is executed, the user is prompted to select a plane from the Tasks panel. The interface then switches to the Sketcher Workbench in sketch editing mode.

  • [Attach sketch](wiki-test2.php?gitpage=Sketcher_MapSketch): attaches a sketch to geometry selected from the active body.
  • [Edit sketch](wiki-test2.php?gitpage=Sketcher_EditSketch): opens the selected sketch for editing.
  • [Validate sketch](wiki-test2.php?gitpage=Sketcher_ValidateSketch): verifies the tolerance of different points and adjusts them.
  • [Check geometry](wiki-test2.php?gitpage=Part_CheckGeometry): Checks the geometry of selected objects for errors.
  • [Create a shape binder](wiki-test2.php?gitpage=PartDesign_ShapeBinder): creates a shape binder referencing geometry from a single parent object.
  • [Create a sub-object(s) shape binder](wiki-test2.php?gitpage=PartDesign_SubShapeBinder): creates a shape binder referencing geometry from one or more parent objects.
  • [Create a clone](wiki-test2.php?gitpage=PartDesign_Clone): creates a clone of the selected body.
  • Create a datum (

    - Create a datum plane: creates a datum plane in the active body. ({{VersionMinus|1.0}})

    - Create a datum line: creates a datum line in the active body. ({{VersionMinus|1.0}})

    - Create a datum point: creates a datum point in the active body. ({{VersionMinus|1.0}})

    - Create a local coordinate system: creates a local coordinate system attached to datum geometry in the active body. ({{VersionMinus|1.0}})

:
(v1.1) : these tools have been replaced by new datum tools.

Part Design Modeling tools

Additive tools

These are tools for creating base features or adding material to an existing body.

  • [Additive pipe](wiki-test2.php?gitpage=PartDesign_AdditivePipe): creates a solid by sweeping one or more sketches along an open or closed path.
  • [Additive helix](wiki-test2.php?gitpage=PartDesign_AdditiveHelix): creates a solid by sweeping a sketch along a helix.
  • Create an additive primitive:

- Additive box: creates an additive box.

- Additive cylinder: creates an additive cylinder.

- Additive sphere: creates an additive sphere.

- Additive cone: creates an additive cone.

- Additive ellipsoid: creates an additive ellipsoid.
