Hi, thanks. No new videos for a little while. UA-cam videos can be slowed to .25 in the YT settings, and turn the music off. And just understand the dragging sketches from their bodies to make the association to the path and dragging them back into. That's something that doesn't get mentioned with FreeCAD much, but it's very useful.

Hi, you can slow it down with UA-cam settings, down to .25. The most important part is how the sketch is constrained. Thanks for watching.

By all means, mirror as much as you can. I found mirror doesn't always work that well, but if it works do it. When I made this I didn't know shapebinders can be edges (paths) too. If I was to make this model today, it would be different, a better, easier model to make.

Make sure it's the active body, when placing the LCS, if it doesn't orient properly, try a different edge (of the 3) or alignment, visually you can see if the profile plane is perp. to the path. With the LCS set properly it's not necessary to drag the profile out of the body to make the association (then drag back into the body). “path must not be a null shape”, not sure. When I made this video I didn't know shapebinders can be edges (paths) that may help in spots. Don't know if this helps, I don't have my CAD PC right now.

When you drag the sketch out, only make the association (coincident to the path). Do the sweep after it's moved back into the body. Hope that helps, but if you're stuck, post a screen shot on Reddit FreeCAD, and I'll take a look at it there.

@@JeffTyndall - Duly posted on reddit. Hope I was thorough enough! No rush for a reply, I worked around it using the next method you showed.

@@JeffTyndall I duly posted it on reddit, but I seem not to be cool enough for there ;-). Anyway, by forcing the receiving part to be active (Right Click -> Toggle Active Part) then the behaviour in your video is replicated. I repeated it on the Rf-R part (about 8:30 on) and it worked again. I'm mystified, but it works.

Hi Sylvia, can you e-mail me at: jeff_tyndall@hotmail.com, I e-mailed you, but I think I had an old address.

@@JeffTyndall Thanks for sharing your FreeCad project! I was looking for something like this. Greetings from Argentina! =)

Good question, there should be. What I should have done is, put a chamfer on all the brick edges 1/2 the mortar thickness. The clay bricks are modelled at the nominal size 3x4x8 (actual is less 1 mortar thickness) so dimensionally it is correct. But the fire bricks are sold as exact size (and modelled) so there should a 1/16" in there. Adding that on to the fire bricks is good idea, and 1/32" chamfer all around. Linear pattern from PartDesign WB bodies have to touch, Array from Draft WB they don't. It's not that tedious, Ctrl C, V, Transform, snaps to a good size, it's not to bad. But ya, mortar joints definitely need to be taken into consideration, and should be modelled.

That's great! This video has gotten more views faster than any of my other videos, so people are definitely interested. The rocket stoves, masonry stoves, I think it's a technology most people aren't aware of and is under utilized. In Canada there is no masonry stove builders store like that kamicenter store in your video. These things will be growing in popularity. Keep up the good work, cheers.

@@JeffTyndall Thanks for the answer! "Kami" is a very powerful organization known in the country and abroad with its own production, a team of stove-makers, a training center, a creative workshop (and much more). But, in other regions (as in mine) this is a popular direction. For example, in our region there is a foundry for the production of furnace casting, which is in demand in the country and abroad. The presence of natural gas in the household reduces the demand for brick ovens, but I agree that it will exist. (In particular, as an element of aesthetics). And stove-makers mainly use Sketchup for designing stoves. (There are many oven libraries on the net). I specifically periodically looked for videos about creating models of brick ovens in FreeCAD, but there were none, except for one video of a guy from Ukraine who gave me inspiration to use FreeCAD in this matter. :) Thank you for the video! Have a good day!

Thanks a lot! I appreciate that. Yes FreeCAD is the best. The assemblies, once you get over a certain number of parts, naming and organizing really helps.

It all PartDesign workbench.

@@JeffTyndall Thank you!!

Это для тех, кто понимает...

It is a clean burning masonry heater, with stove top.

Ya, I know, more of an example than tutorial. YT can be slowed down to 25%, and kill the music. You can drag a sketch out of a body, then use external geometry command from the sketch WB to link to other parts, then drag back into the body to create a parametric part. It's clearer in the stairs video.

@@JeffTyndallUnfortunately I still can't tell what is what even at 25% playback speed

The second part is on my channel, it's always been there. I was planning a 3rd part, where I 'd use boolean slice to fishmouth the pipes and detail them for fabrication. Polytrailer?, cool, I wasn't aware of these. I think a main thing with trailers is, if you are using steel, stay away from closed tubes (squares and rounds) stick to angle and channels, but if you have to use them remember to drill a hole in the bottom. Maybe you can post some of your trailer when it's done, I'd love to see it.

@@JeffTyndall what's wrong with closed tubes?

Hi Eugene, It wouldn't work with fixed dimensions. For the belt to follow the pullies it has to be constrained without fixed dimensions or positions. To find the belt or band saw blade length for your machine: Leave the belt length till the last thing. When the design is done, then measure your belt length (from the sketch), find the closest length belt (or saw blade) from the catalogue. Then with your tensioner 90% retracted (or maybe it's spring or both) reposition the tensioner, re-measure the belt, and adjust until you get the length you need. This assembly might be better with all the pullies fixed, less the tensioner, and just move that around a little. I hope this helps.

Thanks. I like your channel, I subscribed. I'll make another video out of this model, and add a description. It's almost all part design workbench, arrays (of the joists and studs) from draft workbench, windows and doors from BIM workbench, and Assembly 4 workbench for assembly tree.

@@JeffTyndall thank you

If you play it at 0.25 speed and use pause (a lot!) it's easy to follow.

set vid to 0.25 lol, probs mute the audio tho, sounds vaguely demonic to me
