Analyse and export your 3D file with FreeCAD
2.1. Measuring elements and distances
Even if it's easier to design directly using the right dimensions (sizes), thicknesses and distances, it is sometimes necessary to measure parts of an existing volume.
For this freeCAD has metrics for different sizes:
These tools measure angles or distance intuitively:
Generate a mesh :
The meshes are very simple objects, easy to use and which can easily be passed from one application to another without any loss. Therefore 3D software which
For that you simply need to select your part and go to the mesh menu > Create a mesh from
You can change the settings of the mesh and choose the accuracy.
2.2. Choice of format and export
FreeCAD works on a NURBS system, which allows
Although freeCAD does not directly manage the mesh modeling, it is capable to produce mesh for export, making it particularly effective for 3D printing. Freecad allows the import and export in this format, with quite a range of settings.
Note that you must select in the freeCAD tree the objects you want to export.
Some files, due to their complexity or nature, won't be optimal for the export in STL. They will either generate very large files (over 500MB
Files with many curved parts / rounded, or large areas based on vector drawings with a large number of points (text, graphics, etc.), will often generate very heavy files in STL.
It will then be better to export them to a vector format (IGES or STEP-type as mentioned above). These file formats are supported on the Sculpteo online platform.
