Love your videos. Please keep them coming !

Excellent as always many thanks. I always learn something new from your videos.

You are one of the best FreeCAD users i've seen on youtube, would love to buy a full course for beginner to intermediate users.

Beginners: have a little patience with the fillet or chamfer tool and use the up/down buttons next to the fillet size box. Using these up/down buttons allows Freecad the ability to visually change the image. The speed of which depends on your computer's rendering power. The default is 1mm. So, your desired edges are all picked and the fillet size is 1mm. Click the down button (usually changes to zero), then click the up button (back to 1) and watch the image. If the selected edges didn't fillet, 1mm is too large. 1 or more of the edges can not be filleted to 1mm. If it's not critical, highlight the 1. value and change it to something smaller. DON'T click enter, or OK . Instead, move your mouse to a non-action screen location and left click. This will set the fillet value to what you typed AND fillet the selected edges. If the edges didn't fillet, your value is still too high. Repeat the value lowering process until the image changes or a start over will be necessary. Cancel the fillet or complete (an error will be shown) and click the undo arrow once to return.

FreeCAD really needs to solve the issue of filleting up to the line. I makes newbies frustrated and think FreeCAD is dumb because of it

Learning freecad can be a long process. Say, I create 2 or more bodies and boolean cut the selected objects. The part is saved and/or filleted, only to find an error in 1 or more bodies. So, the undo button is used, but the boolean won't undo. I suspect the split function is the next step, but I haven't tried it, yet. Lol. As I progress to more complicated parts (a last part was made from 2 join and 1 cut boolean), the edges to fillet can be very frustrating. Pick 30 edges only to error because 1 edge can not handle the selected radius size. Same goes for chamfers.

Filleting can be quite frustrating for beginners. Error messages may be misunderstood. The size of a fillet is a good example. If the size of the fillet is too large, freecad throws a tantrum, kind of. Instead of undo or other deletions, simply edit the fillet to a smaller size. Ex: I try to create a 1mm fillet and have picked numerous edges. Clicked OK and it errors. Error messages telling me it failed, the part may be flipped over, and the preceeding tree object gets a bad mark. Wow! In some cases, the entire model disappears from the screen. To the beginner, all is lost ... and ... there are NO yt channels describing what to do next, how to retreive all the "lost" work, etc. This is when the use of the 'recompute object' command comes in. Select the last (lowest) object on the active (the 1 you were working on) by right clicking the object and selecting 'recompute object' from the menu. (Side note): Additionally, to get rid of those blue checkmarks on objects within a tree, use this method. Start from the lowest object because recomputing object usually creates a blue checkmzrk on a higher object. What is happening (my guess) is freecad recognizes something changed, causing something else to require 'recomputing object'. Should you go thru this entire process and the blue checkmark is chased all the way to the body object and that errors out (blue checkmarks return to lower objects), something is wrong with 1 or more sketches. Go back an edit it (them).
