Excellent! I knew most of what you covered related to pattern on path, but the trick with loop length and parameter use was extremely helpful. Thanks, Brad!
Another great tutorial! I love the bonus tips! I've never even noticed the three point rectangle! Much easier than drawing lines and adding perpendicular constraints! Clicking on a measurement copies it?! No one's ever told me that! lol Thanks Brad!
Brad your tutorials are very clear, easy to follow and understand. You've taught me so much about fusion 360. I just wanted to give you a big thank you. All the best from the UK
So expanding on this tutorial, what if I need 1) the teeth and space widths to be exact; and 2) the teeth count to be calculated automatically based on the path length. How would I do that?
One of the options in Pattern on a Path is "Spacing" instead of "Extent". I only showed "Extent" and probably should have shown Spacing also. You could use a formula in the quantity dialog that was like loop_length/spacing.
I did a parametric model for GT series belts a year or so back. Rather than forcing teeth count to a nominal length you actually set the path length by the number of teeth x pitch of the profile. You can then reverse your way back out to set pulley spacings.
Its not the point of the exercise otherwise the tooth profile would be an even bigger issue. The math and modelling GT type belts and pullies is non trivial and a whole other subject.
Yes, that is correct. I probably shouldn't have used a toothed belt as an example. I just thought it showed a "pattern along a path" real well. It wasn't aimed on how to create a toothed belt, it was aimed on how to create a pattern along a path. For example, I didn't show the "Spacing" option in the video, which is what you would want to do with a toothed belt. It was the first thing that popped in my head for a pattern on a path example. :) Thanks for watching and responding, though!
Ya, I didn't show tooth spacing, which is one of the options in Pattern on a Path. To keep the videos shorter, I don't show all of the options, but I guess I should. Thanks for watching!
Always look forward to learning something on Friday morning. How would you have handled cog spacing? Change belt length till it ended with a specified number of spaces?
I didn't show it in the video, but one of the options in Pattern on a path is Spacing instead of Extent. So, instead of specifying the Loop Length, you specify the Spacing (of the teeth) and then specify how many teeth you want. However, in this case, your loop length would have to be an exact measurement to equal the spacing of your teeth. For example, if your teeth were spaced 0.5 inches apart, you would want a belt length that ended in a whole or half number.
@@bradtallis8968 I figured. This is a general problem: it is difficult to calculate pattern quantities and extents in a flexible way. I hope Fusion improves the area!
Buongiorno apprezzo molto i tuoi tutorial su Fusion 360 dandomi la possibilita ad imparare ad usarlo . Se possibile per Lei editare i video anche in italiano . Buon lavoro

Glad you found it helpful.
Thank You Sir! Very clear and easy to follow. Much appreciated.

Glad to help!
Great information! Definitely leaned some great time savers and your bonus tips are always awesome.
Thanks, glad you found it useful!
Every Friday You make the CAD easer for us..... thank you
Brilliant, as always.
Thank you! Cheers!
Hey Brad, that was a very useful video, thank you!
Glad you enjoyed it!
As alway Brad, so many top tips.
Happy to help!
Click and hold x 2! Thanks BT.
very nice as usual thanks
Brad, thanks a lot for the tips of this week 😊 HANWE

What about the spacing of the teeth? If this belt is to interface with a cogged wheel or pulley, the spacing of the teeth is important.

@@bradtallis8968 There is a "spacing" option?
@@charlesarterton3646 Yes, in the Pattern on a Path dialog, change the pulldown next to "Distribution" from "Extent" to "Spacing"
you might consider another scenario which is the distance between the tooth i.e. .080" or .0816 I believe are used with small belts and pulleys.
Ya, I didn't show tooth spacing, which is one of the options in Pattern on a Path. To keep the videos shorter, I don't show all of the options, but I guess I should. Thanks for watching!
Excelenete como siempre!! haré un vídeo similar pero en español, espero que te guste, Saludos

Great video! Could the loop_length parameter be referencing the inspected loop length of the sketch? Fully automatic :D
@0:35 Why did your first circle outline turn black, yet the second circle outline stayed blue? Thank you.
Great video, though I thought you were gonna have some neat trick to have the loop length auto feed into that parameter. Would have been cool! ;)
I assume you would have showed this if it were possible: can you avoid hard coding that loop length in by referencing some dimension?
There isn't a dimension for the loop length. I definitely looked!

In the case of a cogged belt you set the length by tooth count x pitch = path rather than a 'nominal' length then cram a number of teeth into that.
loop length !!
