Introduction
The goal of this article is to list the most important currently missing features in FreeCAD and provide workarounds for them. It can be helpful for new users who can't find a particular functionality in FreeCAD.
Workarounds for the Sketcher Workbench
No. |
Missing feature |
Workarounds
|
1 |
Auto snapping to objects (midpoints, center points, quadrants, extensions, intersections) |
|
2 |
Chamfer tool |
|
3 |
Circular pattern |
- creating circular patterns on part level (after the sketch is turned into a volume)
|
4 |
Offset tool |
|
5 |
Rotate tool |
- to rotate the whole sketch: change its Placement property
- to rotate a selection inside the active sketch:
- remove constraints that prevent the rotation, e.g. with Sketcher RemoveAxesAlignment
- optionally add constraints between the objects to be rotated
- apply an appropriate Sketcher ConstrainAngle constraint or drag a vertex of one of the objects
|
6 |
Scale tool |
|
7 |
Adaptive dimension constraint |
|
8 |
Inputting coordinates and dimensions on the go (when drawing an object) |
|
9 |

- tangency applied to endpoints instead of edges
|
10 |
Checking geometric and mass properties of the sketch (area, center of mass, second moments of area and so on) |
|
11 |
Possibility to use the results of the External Geometry tool directly for operations on the sketch |
- manually outlining the geometry created by this tool
|
12 |
Projecting multiple edges at once with the External Geometry tool when a face is selected |
- projecting edges individually
|
13 |
3D sketches |
|
14 |
Projection of cut edges when making a sketch on a plane cutting through an object |
- create a Link from the object, and slice that object to get actual cut edges.
|
15 |
View section tool showing filled cuts |
- if the sketch is plane-parallel to one of the main planes of the global coordinate system: use Part SectionCut
|
Workarounds for the Part Workbench and Part Design Workbench
No. |
Missing feature |
Workarounds
|
1 |
Checking geometric and mass properties of the model |
|
2 |
Displaying center of mass of the model (part or assembly) |
|
3 |
Clipping plane that doesn't make the model look like it's hollow |
- changing lighting in part’s view settings to one side (very rough equivalent, problem with multicolored parts)
- Persistent section cut tool - deselect all planes before pressing Close, doesn’t work for intersecting parts in assemblies
|
4 |
Creation of an axis on the intersection of 2 planes and a plane midway between two faces/points, possibly more variants for datum creation |
|
5 |
Automated midsurface extraction (for thin-walled parts) |
|
6 |
Projecting (mapping/wrapping) sketches on non-planar (e.g. cylindrical) faces |
|
7 |
Support for multiple solids within a body |
- creating a separate body for each solid
|
8 |
Selecting which part of the sketch to pad |
|
9 |
Fillets and chamfers that can consume adjacent faces/edges |
- making fillets with a slightly smaller radius (e.g. 6.4999 instead of 6.5 mm)
|
10 |
Variable radius for the PartDesign Fillet tool |
|
11 |
Parametric curves |
|
12 |
Cosmetic threads |
- adding cosmetic threads on the TechDraw page
- modeling true threads, for holes those can be generated automatically using Hole tool
|
13 |
Partitions (splitting surfaces and volumes with sketches and datum planes while keeping the number of parts unchanged) |
|
14 |
Guide rails for Additive Pipe and Additive Loft or their equivalents in the Part Workbench |
|
15 |
Twist for Additive Pipe or Part Sweep |
|
16 |
Bending existing parts |
|
17 |
Pattern along a curve |
|
18 |
Cut scope - cut tools affecting only selected part of the model |
|
19 |
Merging adjacent faces |
- for faces of a PartDesign Body: change the Refine property of the last Feature to
true .
- for co-planar faces: use Draft Upgrade twice to get a Draft Wire, Draft Downgrade the wire to get a face.
|
20 |
Hole tool using points from sketches |
- drawing circles for the Hole tool
|
21 |
Datum points from coordinates |
|
22 |
A tool for automatic creation of ribs |
|
Workarounds for the TechDraw Workbench
No. |
Missing feature |
Workarounds
|
1 |
Advanced section views (half, broken out, offset and aligned sections) |
- using the Slice apart tool to physically cut the model and then creating its view
|
2 |
Surface quality annotations |
|
3 |
Auto diameter dimension on side views |
- manual addition of the diameter symbol
|
4 |
Sketching in drawings |
|
5 |
Shaded views in drawings |
|
6 |
Ordinate dimensions |
|
7 |
Broken (interrupted) views |
- creating broken views manually:
- sketch two wavy or zig-zag lines close to the ends of a long part and extrude them towards the model creating surfaces for the cut
- use the Part Slice tool to cut the model with these surfaces
- hide the middle piece and move one of the remaining pieces towards the other
- create a view of these objects
- if needed, make the lines of the cut dashed (using the TechDraw DecorateLine tool)
- if lines of the cut have to be extended, create a view of the sketch used in the first step and align it with the cut
- to obtain a proper value of the length of the cut part, you can either change the dimension value manually (after enabling the Arbitrary Text option) or link it to the distance between the end vertices of the original part
|
8 |
Excluding ribs from hatching |
- in some cases it might be sufficient to use the first workaround mentioned here and manually create a section with a custom cutting line
|
Workarounds for the FEM Workbench
No. |
Missing feature |
Workarounds

1 |
Beams with arbitrary cross-section |

7 |
Composite shells |
|
8 |
Simple creation of node and element sets |
