Wires being offset independently don't have to be coplanar. Wires being treated collectively must be coplanar. The Groove Tool allows you to create grooves around objects.
#FREECAD OFFSET GROOVE HOW TO#
This is in tight relationship with how holes in faces are treated. 2.32K subscribers 5.5K views 2 years ago FreeCAD Tools This video shows you how to use FreeCADs Groove Tool. Also, in collective mode, directions of wires are important, and influence direction of offset.
Likewise, wire3 and wire4 are treated collectively, but independently of wire1+wire2. For example, if the structure is like compound(wire1, wire2, compound(wire3, wire4)), wire1 and wire2 will be treated collectively, but independently from wire3 and wire4. Only wires within a compound are coupled. If "true", the wires are offset in collective manner. If "false", wires are offset independently, intersections between resulting wires are ignored.
Data Intersection ("false", "true"): sets if multiple wires are treated collectively or independently. "Intersection": offset segments are extended till they intersect. If "Arc", offset segments are connected with an arc of circle, centered at the vertex. FreeCAD Part Design Subtractive Groove - How to use a revolve to subtract from a Body mathcodeprint 12.6K subscribers Subscribe 7.2K views 2 years ago This Tutorial uses the Subtractive Groove. Data Join ("Arc", "Tangent", "Intersection"): sets the behavior around kinks. If "Pipe", the wire is outlined as if it was an extremely thin closed contour. Data Mode ("Pipe" or "Skin"): sets how non-closed wires are processed. If negative, the wire/face is shrunk instead. Data Value: The distance to enlarge the wire/face by. Above: sketch (A) is revolved around axis (B) resulting groove on solid (C) is shown right. Single line segments cannot participate in collective offset either. The Groove tool revolves a selected sketch or profile about a given axis, cutting out material from the support. Offsetting wires made of single line segment is not supported (because line segment doesn't define a plane). "Tangent" join mode doesn't work (OCC 7.0.0). Fill="true" doesn't work when collectively offsetting open wires in "Skin" mode. When offsetting circles, sometimes they are offset in unexpected direction (e.g. When offsetting circles that have non-zero Placement, the result is placed wrongly. The problem seems to be specific to circles other shapes seem to close out properly. Enlarging faces with circular holes by an amount large enough to cause holes to close up, a crash occurs (OCC 7.0.0).

On Windows, these crashes are converted to exceptions and don't generally cause FreeCAD to close on other OS'es it is not the case, so it is advisable to save project before attempting to use the tool. Using the tool can crash FreeCAD (see next point). Most of non-default modes will only work with OCC 7.0.0 or later. App Link objects linked to the appropriate object types and App Part containers with the appropriate visible objects inside can also be used as source objects. There can be multiple wires in one object, not necessarily coplanar. Posted about my SAB listing a few weeks ago about not showing up in search only when you entered the exact name. Or enlarges/shrinks a planar face, similarly. Thank you very much.The Part Offset2D tool constructs a wire, parallel to the original wire, at a certain distance from it. I would highly appreciate any tips on how to fix the issue, as well as to gain an understanding of what causes this problem to avoid this issue in my actual part. However, as soon as the groove angle in the feature is increased beyond a certain threshold, the groove is not correctly computed. I want to remove the geometry marked in red using the "Groove C" feature. I created a similar (simplified) model to illustrate the problem. Unfortunately in my actual (more involved) model, the suggested approach does not fix the issue. The idea which resolved the issue was to change the rotation axis of a previous Revolution feature from "Horizontal sketch axis" to "Base Y axis", despite both options actually referring to the same axis. I used a very simplified model to illustrate my issue, which has successfully been resolved by following a suggestion from domad, see. I recently made a post on a PartDesign issue where a Groove feature failed.
