One of the biggest difficulties for new users of FreeCAD, is to know in which workbench to find a specific tool. The table below will give you an overview of the most important workbenches and their tools. Refer to each workbench page in the FreeCAD documentation for a more complete list.
Four workbenches are also designed to work in pairs, and one of them is fully included into the other: Arch contains all the Draft tools, and PartDesign all the Sketcher tools. However, for clarity, they are separated below.
The Part Workbench provides basic tools for working with solid parts: primitives, such as cubes and spheres, and simple geometric operations and boolean operations. Being the main anchor point with OpenCasCade, the Part workbench provides the foundation of FreeCAD's geometry system, and almost all other workbenches produce Part-based geometry.
|Box||Draws a box||Cone||Draws a cone|
|Cylinder||Draws a cylinder||Sphere||Draws a sphere|
|Torus||Draws a torus (ring)||Create primitives||Creates various other parametric geometric primitives|
|Shape builder||Create more complex shapes from primitives||Union||Fuses (unions) two objects|
|Common||Extracts the common (intersection) part of two objects||Cut||Cuts (subtracts) one object from another|
|JoinConnect||Connects interiors of walled objects||JoinEmbed||Embeds a walled object into another walled object|
|JoinCutout||Creates a cutout in a wall of an object for another walled object||Extrude||Extrudes planar faces of an object|

The Draft Workbench provides tools to do basic 2D CAD drafting tasks: lines, circles, etc... and a series of generic handy tools such as move, rotate or scale. It also provides several drawing aids, such as grid and snapping. It is principally meant to draw the guidelines for Arch objects, but also serves as FreeCAD's "swiss knife".
|Line||Draws a line segment between 2 points||Wire||Draws a line made of multiple line segments (polyline)|
|Circle||Draws a circle from center and radius||Arc||Draws an arc segment from center, radius, start angle and end angle|

|Move||Moves or copies objects from one location to another||Rotate||Rotates objects by a certain angle around a point|
|Offset||Offsets an object to a certain distance||Trimex||Trims, extends or extrudes an object|
|Upgrade||Turns or joins objects into a higher-level object||Downgrade||Turns or separates objects into lower-level objects|

|Mirror||Mirrors objects across a line|
The Sketcher Workbench contains tools to build and edit complex 2D objects, called sketches. The geometry inside these sketches can be precisely positioned and relationed by the use of constraints. They are primarily meant to be the building blocks of PartDesign geometry, but are useful everywhere in FreeCAD.
|Point||Draws a point||Line||Draws a line segment from 2 points|
|Arc||Draws an arc segment from center, radius, start angle and end angle||Arc 3 points||Draws an arc segment from two endpoints and another point on the circumference|

|Coincident||Affixes a point onto (coincident with) one or more other points.||Point on object||Affixes a point onto another object such as a line, arc, or axis.|
|Vertical||Constrains the selected lines or polyline elements to a true vertical orientation. More than one object can be selected before applying this constraint.||Horizontal||Constrains the selected lines or polyline elements to a true horizontal orientation. More than one object can be selected before applying this constraint.|
|Parallel||Constrains two or more lines parallel to one another.||Perpendicular||Constrains two lines perpendicular to one another, or constrains a line perpendicular to an arc endpoint.|
|Tangent||Creates a tangent constraint between two selected entities, or a co-linear constraint between two line segments.||Equal length||Constrains two selected entities equal to one another. If used on circles or arcs their radii will be set equal.|
|Symmetric||Constrains two points symmetrically about a line, or constrains the first two selected points symmetrically about a third selected point.||Lock||Constrains the selected item by setting vertical and horizontal distances relative to the origin, thereby locking the location of that item|
|Horizontal distance||Fixes the horizontal distance between two points or line endpoints. If only one item is selected, the distance is set to the origin.||Vertical distance||Fixes the vertical distance between 2 points or line endpoints. If only one item is selected, the distance is set to the origin.|
|Distance||Defines the distance of a selected line by constraining its length, or defines the distance between two points by constraining the distance between them.||Radius||Defines the radius of a selected arc or circle by constraining the radius.|
|Internal angle||Defines the internal angle between two selected lines.||Snell's law||Constrains two lines to obey a refraction law to simulate the light going through an interface|
|Internal alignment||Aligns selected elements to selected shape (e.g. a line to become major axis of an ellipse)||Map sketch||Maps a sketch to the previously selected face of a solid|
|Merge||Merge two or more sketches||Mirror||Mirrors selected elements of a sketch|
The Part Design Workbench contains advanced tools to build solid parts. It also contains all the tools from the sketcher. Since it can only produce solid shapes (the rule number one of Part Design), it is the main workbench to use when designing pieces (parts) to be manufactured or 3D-printed, as you will always obtain a printable object.
|Pad||Extrudes a solid object from a selected sketch||Creates a pocket from a selected sketch. The sketch must be mapped to an existing solid object's face|

|Shaft wizard||Generates a shaft from a table of values and allows to analyze forces and moments||Involute gear wizard||Allows you to create several types of gears|
The Arch Workbench contains tools to work with BIM projects (civil engineering and architecture). It also contains all the tools from the Draft workbench. The main use of the Arch Workbench is to create BIM objects or give BIM attributes to objects built with other workbenches, in order to export them to IFC.

Other built-in workbenches
Although the above summarizes the most important tools of FreeCAD, many more workbenches are available, among them:
- The Mesh Workbench allows to work with polygon meshes. Although meshes are not the preferred type of geometry to work with in FreeCAD, because of their lack of precision and support for curves, meshes still have a lot of uses, and are fully supported in FreeCAD. The Mesh Workbench also offers a number of Part-to-Mesh and Mesh-to-Part tools.
- The Raytracing Workbench offers tools to interface with external renderers such as povray or luxrender. Right from inside FreeCAD, this workbench allows you to produce high-quality renderings from your models.
- The Spreadsheet Workbench permits the creation and manipulation of spreadsheet data, that can be extracted from FreeCAD models. Spreadsheet cells can also be referenced in many areas of FreeCAD, allowing to use them as master data structures.
- The FEM Workbench deals with Finite Elements Analysis, and permits the performing of pre- and post-processing FEM calculations and to display the results graphically.
A number of other very useful workbenches produced by FreeCAD community members also exist. Although they are not included in a standard FreeCAD installation,they are easy to install as plug-ins. They are all referenced in the FreeCAD-addons repository. Among the most developed are:
- The Drawing Dimensioning Workbench offers many new tools to work directly on Drawing Sheets and allow you to add dimensions, annotations and other technical symbols with great control over their aspect. The Drawing Dimensioning Workbench is no longer maintained.
- The Fasteners Workbench offers a wide range of ready-to-insert fasteners objects like screws, bolts, rods, washers and nuts. Many options and settings are available.
- The A2plus workbench offers a series of tools to mount and work with assemblies.
