Appreciate your delivery. Nice pace, WELL DONE. I've been contemplating threads for a while and this certainly made it doable. Printing a box right now. THANKS!
Thanks for the video. I see your video uses FreeCAD version 0.21.1, but I'm using 0.21.2 . I don't know if that makes a difference. I followed your example and printed the top and bottom. They printed fine with no obvious print defects, but they don't fit together, the top is too small in diameter. Following your example more closely, when you built the threads on the bottom, you can see that the outer diamter of the threads appears to be slightly smaller than the outer diameter of the rest of the part. When I do it, it looks like the outer diameter of the threads and the rest of the part are the same. This really shows up when you overlay your sketch for the top rotation. The inner diameter (before the threads are cut) of the top is much closer to the inner shoulder of the bottom threads on my version. Also, in your video, after you cut the ScrewDie object, but with threads set to false, the 3d image shows that the ScrewDie object outer diameter is slightly smaller than the rest of the object while on mine, the diameters appear the same. I see there are some setup parameters for the Fasteners workbench. Have you changed yours from the defaults? Also, when I view the data pane for the ScrewTap object from the Fasteners workshop, I have all the parameters set the same as yours, but my data panel shows one additional parameter, Offset Angle, that doesn't show in your video. Thanks
Hello. If I want to extract volume(bottle or exhaust/intake manifol of car) I need to plug all the outlets of the solid model, then (theoretically speking) erase one outside surface of the solid, which will make the entire outside of the solid model to fall apart and create only surfacessss and then the inside volume should stay as a solid. I can then use it as a model for the casting core and also test the volume of the bottle....I just cannot find anywhere (user forums or youtube vids.), how to erase a surface from the solid body. Do you have any solution?
I am not sure you can erase a surface. Depending on the complexity of the surface you may be able to create a boolean operation to subtract the surface
Your tutorial is excellent and easy to follow, but this time I'm stuck. When I use "Boolean" the screw is flat against the body, while in your video it is slightly sunken. When I set tread = true the report view shows "Recompute failed!" with a red exclamation point on "Boolean" I have followed your tutorial step by step, the exact same numbers several times and can't see any difference from what you did. I'm on the same version as you. Any ideas on what could result in this error and what to do to fix it?
@@Adventuresincreation Well, something is obviously wrong, all measurements are identical to yours. Could be something with the settings in Freecad or maybe something in the system settings otherwise... Just have to keep trying! Thanks anyway!
@@Adventuresincreation Thanks for the offer, but a complete uninstall and reinstall of FreeCad fixed the problem! Now all that remains is to get the rest of my settings back in place!-)
I think you will see the offset is where the thread starts. - I will put something in my next video that shows it more clearly. - Thanks for the heads up!
