FreeCAD: Basic Intersection Workflow in Part Workbench

Тәжірибелік нұсқаулар және стиль

The video demonstrates how to create an intersection of two profiles in FreeCAD to model an object and demonstrates the technique of looking at a model from two sides to create the finished result.
The first step is to sketch the bottom profile of the object on the XZ plane. Straight lines and arcs are used to approximate the profile.
The second profile on the top is then sketched on the XY plane using a polyline. External geometry is used to align points between the two profiles.
The profiles are then extruded in opposite directions, past the length of the object, to create two intersecting solids.
An intersection operation is performed to combine the solids and create the final modeled object with the helical support.
Additional modifications are made like mirroring the top profile to the bottom to demonstrate flexibility in modifying profiles.

    I have used the intersection of 2 profiles a lot since you first introduced in the create a spoon lesson, very powerful yet basically very simple! Thank You

    extremely helpful. I'm new to FC and Cad in general and had been wondering how certain parts with to me looked like complex angle were made and boom you nailed it "intersection". I appreciate your videos.

    Glad it was of help. There are more videos coming regarding breaking down objects and figuring out how to get them into freecad similar to the CAD thinking mini series I did.

    I like the "Part" workbench/workflow a lot more than the the "Part Design" workbench. I find the step-by-step approach of part design very limiting. The tree-like structure that results from the "Part" workflow is much more logical for most shapes and also more robust against "breaking" a model after changes of previous steps. As an added benefit the "Part" workbench works together a lot better with the functions of other workbenches (for me that's actually at least as, if not more, important).

    I am with you on that. I like to work with surfaces and then join them altogether and the part really excels with that. It's also very good for experimenting worth build. Thanks for adding your thoughts. It's great for me and others alike. Thank you 😊👍

    The original holes was angled. The right way to do this is to place your POV accordingly (i.e. with some angle) and then create a Shape2Dview from Draft workbench, and transform it to a sketch. Then make the intersections as you depicted in this video. In total you should use 2 intersection ops.

    You could use the Create Corner Preserving Fillet for the two curved.

    Very nice video! From the name, I suspect the original part is a supporting bracket for a helix structure (think spiral staircase). Having seen a helix used with model railways to allow storage of trains below the rail layout in a compact way, I'm wondering if it might not be part of something like that - basically the trains spiral up a helix from the storage track to get onto the layout above

    Thank you glad you enjoyed it. Yes you got it, it's exactly that to support a helix but this one of i remember rightly it was for radio communications.

    I'm a bit surprised, that you didn't mention the modifier key [M] for the polyline.

    I have done in previous video but I find some beginners tend to struggle with the different modes and positioning the geometry in relation to the last key press.

    I would like to know how would you sweep a sketch along a path created by a datum plane intersection. For instance, an sphere with 10 mm radius. Create a datum plane with a 3 mm offset from origin. Create an sketch on the datum plane where the intersection of the datum plane with the sphere is brought as an external reference geometry.

    Hello. Patron member here. What Are your thoughts on a 3d mouse? And how do they work with freecad?

    Hi hope your doing well, I have to be honest I have never tried a 3D mouse in any CAD / 3D packages let alone freeCAD sorry. But if anyone out there has any recommendations / advice please feel free to comment.
