Введение
Цель данной статьи перечислить некоторые отсутствующие в настоящее время возможности в FreeCAD и предоставить обходные пути для их решения. Это может быть полезно для начинающих пользователей, которые не могут найти требующиеся инструменты, среди тех что существуют в FreeCAD.

Обходные решения для верстаков Part и Part Design
No. | Missing feature | Workarounds |
---|---|---|
1 | Check the geometric and mass properties of the model |
|
2 | Display the center of mass of the model (part or assembly) | |
3 | Clipping plane that doesn't make the model look like it's hollow |
|
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 | Project (map/wrap) sketches on non-planar (e.g. cylindrical) faces |
|
7 | Support for multiple solids within a body |
|
8 | Select which part of the sketch to pad |
|
9 | Fillets and chamfers that can consume adjacent faces/edges |
|
10 | Variable radius for the PartDesign Fillet tool |
|
11 | Parametric curves | |
12 | Cosmetic threads | |
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 PartDesign AdditivePipe 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 |
|
20 | Hole tool using points from sketches |
|
21 | Datum points from coordinates |
|
22 | A tool for automatic creation of ribs (structural reinforcements) |
|
23 | A tool for automatic creation of domes |
|
Обходные решения для верстака TechDraw
No. | Missing feature | Workarounds |
---|---|---|

|
2 | Auto diameter dimension on side views |
|
3 | Sketch in drawings |
|
4 | Shaded views in drawings |
|
5 | Ordinate dimensions |
|
6 | Broken (interrupted) views |
|
7 | Exclude ribs from hatching |
|

|
Workarounds for the FEM Workbench
No. | Missing feature | Workarounds |
---|---|---|
1 | Beams with arbitrary cross-section |
|
2 | Pressure load on shells, distributed load on beams | |
3 | Support for multiple meshes and thus possibility to define contact between touching (not separated) faces |
|
4 | Apply torque to any surface |
|
5 | Define rigid bodies and virtual elements |
|
6 | Advanced material models (hyperelasticity, creep and so on) |
|
7 | Composite shells |
|
8 | Simple creation of node and element sets as well as surfaces |
|
9 | CalculiX keyword editor that can fold data lines and allow changes not only right before running the analysis |
|
10 | Meshing with hexahedral elements |
|
11 | Analyses with 2D (plane stress, plane strain, axisymmetric) elements |
|
12 | Multistep analyses (e.g. preload for frequency/buckling analysis) |

General workarounds
No. | Missing feature | Workarounds |
---|---|---|
1 | Official assembly workbench |
|
2 | Improved appearance/rendering of 3D models | |
3 | Status bar instructions (“Now pick this …”) for many tools that would benefit from them (e.g. Sketcher constraints) |
|
4 | Consistent selection order - some tools require the user to pick the geometric entity first while others allow selection after enabling the tool |
|
5 | More GUI customization options - pie menus, different icon styles and themes and so on |
|
6 | Selection filter (picking only faces, edges, points and so on) |
|
7 | Assembly workbench with an option to constrain parts to the origin and to datums |
|
8 | Transform tool with an option to move and rotate with respect to edges and global coordinates |
|
