Watched all 8 so far and I have zero prior experience with CAD software but basic 3d animation knowledge and this helped me span the gap I was struggling to work through. So double thank you.
Very interesting! I would like to know what accuracy the system uses(number of decimals) and also if you can convert these curved meshes to smooth and dimesionaly accurate surfaces? (of course, for the flat surface, there is no issue)
The accuracy is very accurate, you can import am image and scale it to an exact dimension and model over this as a reference and you will get an exact fit. I saw a video on TH-cam somewhere where this was put into practice and the results was more or less dead on there was a minute different and I am talking 0.000x mm out when he compared with calipers but it had no affect on fitting.
You can right click shade auto smooth and the surface will be smooth but i do not know if you can print that. The other way is to increase the number in the mesh curve resolution to 48 or the number that works for you and your surface will be smooth.
Great tutorial! just a question...i have and issue when apply distance constrain....the numbers dont appear but if i click on the line i can change the distance and work but numbers isnt there :(
I have an issue when I add the new workspace on the revolveprofile, blender shows orange lines after add the workplane. I only toggle on x-ray mode,but it still show those wireframe lines
Just answering in case anyone else wonders about that. Centre of the plane was moved at 12:00 but viewport wasn't aligned with the Z-Axis (Numpad-7) so instead of x and y only it was also moved slightly on the z-axis.
I have three doubts: 1. In real life, we have a local sense of "horizontal" and "vertical". So my "vertical" direction in India would be at an angle for someone in the UK in the 3D space, and my +z direction would be -z direction for someone in the US. Likewise, in the outer space, we do not have any sense of up/down, left/right, horizontal/vertical, etc.! In the same way, in Sketcher, our workplane is in any random orientation (xy, yz, xz or even aligned to any face of a geometry). So what do we mean by "horizontal" and "vertical" in such a workplane? (This doubt came to me because at 16:05 you talk about "vertical" constraint, but the overlay shows a *horizontal* line.) 2. You explained that placing the vertical constraint once again locks the position of the line. But that's completely illogical: Applying the same constraint twice to the same element should not change its behavior at all. In fact, Sketcher should not allow us to apply the same constraint multiple times to any element. 3. From the same experiment, now I wonder if the horizontal/vertical constraints work in two different ways: (a) make the alignment of the line vertical or horizontal. (b) lock the position of the element in horizontal/vertical direction. So a vertically constrained element can move in horizontal direction only. When I draw a line, a horizontal line overlay appears at its midpoint if the line is nearly horizontal; and a vertical line overlay appears near its midpoint if it is nearly vertical. So this behavior matches (a) above. But your little "what if-" scenario at 16:05 demonstrates that if we apply the same constraint to a line for a second time, that second constraint behaves like (b). I did not see any other resource/tutorial describe this!

That's great to hear. Thank you for sharing that.
Great tutorial! 🙏🏻
Glad you liked it!

20:57 it looks like the second sketch is not sitting directly on top of the revolved object. It’s down a bit in the Z axis. Why is that?
