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.

We call sponsoring the act of donating money recurrently to the FreeCAD project. You can do that as an individual or as a company or institution, through different channels or platforms, depending on your preferences.

Sponsoring FreeCAD allows its developers to count on a steady flow of income, so it allows the FPA to plan things ahead, and the FreeCAD developers to invest themselves more seriously into FreeCAD.

To encourage persons and companies to sponsor the FreeCAD project, we have created different sponsoring tiers. When donating regularly to the project, unless you prefer to stay anonymous, your name, company name and/or logo will be featured on this website, depending on the tier you fit into:

  • ♥ Normal sponsor : 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.
  • 🥉 Bronze sponsor : from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.
  • 🥈 Silver sponsor : 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.
  • 🥇 Gold sponsor : 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 Preferences

Introduction

The Part Workbench and the PartDesign Workbench use the same preferences. They can be found in the Preferences Editor. In the menu select Edit → Preferences... and then Part/Part Design. This group is only available if one of the workbenches has been loaded in the current FreeCAD session.

Some advanced preferences can only be changed in the Parameter editor. See Fine-tuning.

This page has been updated for version 1.0.

Available preferences

There are three pages: General, Shape view and Shape appearance.

General

On this page you can specify the following:

+++ | Name | Description | +=====================================================================================+=========================================================================================================================================================================================================================+ | | If checked, the Boundary representation (BRep) of the model is validated after boolean operations. | | Automatically check model after boolean operation | | | | | +++ | | If checked, the model is refined after boolean operations. | | Automatically refine model after boolean operation | | | | | +++ | | If checked, the model is refined after changes to source sketches of objects. | | Automatically refine model after sketch-based operation | | | | | +++ | | If checked, Bodies can have multiple solids. (v1.0) | | Allow multiple solids in Part Design Body by default (experimental) | | | | | +++

Shape view

On this page you can specify the following:

+++ | Name | Description | +=======================================================================+========================================================================================================================================================================================================================================+ | | The maximum linear deflection of the tessellated objects from their surface. | | Maximum deviation depending on the model bounding box | | | | | +++ | | The maximum angular deflection from one tessellated object section to the next section. | | Maximum angular deflection | | | | | +++

Shape appearance

An explanation of the colors can be found here.

On this page you can specify the following:

+++ | Name | Description | +========================================+======================================================================================================================================================================================================================+ | | The diffuse color for new shapes. If the option Random is set, a random color is used instead. | | Shape color | | | | | +++ | | The ambient color for new shapes. (v1.0) | | Ambient shape color | | | | | +++ | | The emissive color for new shapes. (v1.0) | | Emissive shape color | | | | | +++ | | The specular color for new shapes. (v1.0) | | Specular shape color | | | | | +++ | | The transparency for new shapes. (v0.21) | | Shape transparency | | | | | +++ | | The shininess for new shapes. (v1.0) | | Shape shininess | | | | | +++ | | The line color for new shapes. | | Line color | | | | | +++ | | The line thickness for new shapes. | | Line width | | | | | +++ | | The color for new vertices. | | Vertex color | | | | | +++ | | The size for new vertices. | | Vertex size | | | | | +++ | | The color of bounding boxes in the 3D view. | | Bounding box color | | | | | +++ | | The font size of bounding boxes in the 3D view. (v1.0) | | Bounding box font size | | | | | +++ | | If checked, the color of the interior side of faces will be the same as the exterior side. If not checked either the backlight color, if enabled, or black is used instead. | | Two-side rendering | | | | | +++ | | The text color for new document annotations. | | Text color | | | | Currently these annotations can only be added by using the Python console: | | | | | | | +++

Tessellation

In order to display an object efficiently its surface is tessellated, i.e. it is displayed with some small deviations from its real surface. This applies not only to PartDesign models, but also to other objects in FreeCAD.

There is a lower limit for the tessellation of 0.01%. If you really want to spend the additional time you can reduce the lower limit even further by opening the Parameter editor.

In the Parameter editor navigate to BaseApp → Preferences → Mod → Part, right-click on MeshDeviation, and choose Change value from the context menu. Set the value to the minimum tessellation of your choice. Please keep in mind that the value is in %, i.e. for a value of 0.005% you have to enter {{Value|0.00005}}. The smallest possible value is {{Value|1e-7}}. Note that in the Preferences Editor you will still see 0.01% even if you have set a lower value.
