Solid from Faces¶
Dependencies¶
This node requires FreeCAD library to work.
Functionality¶
This node takes several Solid Face objects (i.e. Surfaces trimmed by some edges), and “glues” them to construct a Solid object. In order to make a proper Solid object, the faces must already have their edges and vertices exactly coinciding. Usually the only way to guarantee that is to construct all these Faces from the same set of Edges.
By default, the node will check that the Solid object it constructed is “valid” in terms of FreeCAD’s OCCT kernel: all faces have coinciding edges, all normals are pointing outside, and so on. If the node will find that the solid is not valid, it will try to automatically fix it. If this automatic fix process fails, the node will raise an exception (become red) and processing will stop.
NOTE: some operations with Solid objects which are not “valid” are known to cause crashes. So it is strongly recommended to have “Validate” parameter turned on.
Solid Face object can be created with nodes from “Make Face” submenu (such as “Face from Curve”); also any NURBS or NURBS-like surface can be used as a Solid Face.
Inputs¶
This node has the following input:
SolidFaces. Solid Face objects to make a Solid from. This input can consume data with nesting level from 1 (list of faces) to 3 (list of lists of lists of faces). The node will make one Solid object from each list of faces. This input is mandatory.
Parameters¶
This node has the following parameters:
Body is closed. If checked, the node will check that the constructed Solid object is closed, i.e. does not have open edges. If it finds that the body is not closed, the node will raise an exception (become red) and processing will stop. So if this parameter is checked, you can be sure that all Solid objects it generates are closed. If not checked, the node will not perform such check, and can generate not-closed objects. Checked by default.
Validate. This parameter is available in the N panel only. If checked, the node will check that the Solid object it constructed is “valid” in terms of FreeCAD’s OCCT kernel: all faces have coinciding edges, all normals are pointing outside, and so on. If the node will find that the solid is not valid, it will try to automatically fix it. If this automatic fix process fails, the node will raise an exception (become red) and processing will stop. So if this parameter is checked, you can be sure that the generated Solid object is “valid”. If not checked, the node will not validate the created object. In most cases, you have to check this parameter; it is checked by default. NOTE: some operations with Solid objects which are not “valid” are known to cause crashes.
Tolerance. This parameter is available in the N panel, only if Validate parameter is checked. Tolerance for automatic “fix” process. The default value is 0.001.
Outputs¶
This node has the following output:
Solid. The generated Solid object.
Example of usage¶
Make a side surface by lofting between three cubic splines; make top and bottom faces with “Frame from Curve” node from the first and the last spline; then build the Solid object from these three surfaces:
