ago I'm going to have to make use of the Clone/Copy mechanism in sketcher next time. This can be further confused as we can move the position of the sketch origin. edit: There's a macro available, with some limitation, but it's better than nothing: 6 40 comments Best wtech2048 3 yr. The selected sketch is rotated around an axis and removes material that it intersects. You will notice it seems to be off the origin, but the sketch origin is in fact still in the same place. The Subtractive Groove uses a Sketch to remove material from a Body. Here is the sketch showing the against the Body Origin.
the confusion starts when we change things up a bit.įirst lets move the center of the sketch circle.Below we have a circle that is not placed on the Sketch origin. If you notice the Sketch, the Pad and and Both origins are all coincident. Pictured below we see a Sketch, its Pad the Sketch Origin ( Red,Green) and the Body Origin (Blue) By default the sketch origin is coincident with the Body origin. In Part Design all sketches are contained within a body. Let’s try to Sort it all out starting with a Sketch In Part Design the following items have distinct Origins Subtractive tools: Pocket, Hole, Groove, Subtractive loft. FreeCAD tries to predict the attachment mode for you, and filters the modes available for the given selection. A face on the existing solid can alternatively be used. If we leave the sketch where it is, the example would be too easy, so lets change the sketchs position by altering its attachment offset. Above: sketch (A) is revolved around axis (B) resulting groove on solid (C) is shown right. This can become confused by the fact that there are multiple origins, and methods of repositioning based on those origins. The Groove tool revolves a selected sketch or profile about a given axis, cutting out material from the support. Thank you very much.Positioning objects in FreeCAD can become confusing, when the Objects origins are not clear. 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. Again I am having an understanding problem in how to groove towards from the green face in direction 0 zero XY plane. There can be multiple wires in one object, not necessarily coplanar. Post here for help on using FreeCADs graphical user interface (GUI). Your new datum plane will automatically be attached to the base XZ plane (if that is the one you selected).
Or enlarges/shrinks a planar face, similarly. Easiest way to do it is to unfold the 'Origin' object in the tree, select (click) the base plane you want, and then create your datum plane. However, as soon as the groove angle in the feature is increased beyond a certain threshold, the groove is not correctly computed. Description The Part Offset2D tool constructs a wire, parallel to the original wire, at a certain distance from it. 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.
