FreeCAD: This object is harder than it looks! Helping a Patreon Model a Comb
ฝัง

- We learn how to brake objects down in FreeCAD and decide on the modelling techniques we need to use. Some models can be thought as being easy to model until we look at the subject more deeply. I help a patreon with modelling a comb but it's not the case of a simple extrude with a linear pattern. It is more complex in form when we look at it. Curved surfaces in multiple planes along with a linear pattern that follows a curve we learn how our choice of the part design workflow can be complimented with the draft workbench and how to use both safely together.

Great. Thank you uns happy X-Mas 🙂
Glad you enjoyed. And I hope you have had a great Xmas and wishing your all the best for the new year.
Looks complex at the beginning, but it is simple at the end. Thank you!
You are welcome! 😊 Everything is hard until you in know how 😁
It was
I don't know if this could have been a bit easier...
I would have padded the outside of the comb, then do a linear pattern for the comb teeth, then a pocket to set the inclination angle, and finally do the outside fillet
but regardless, I still appreciate that you explain and show us other tools, tips, tricks, etc.
Hi, Darren. Great job! In 36:12, couldn't you have made the top two points of the rectangle symmetrical with respect to the Y axis, to avoid the gap in the middle of the comb?
Place the arc center on the y axis then you don't need the tangent construction line.
Or just make the arc and line tangent.
any reason you made the arcs tangent to a construction line as apposed to normal to the normal to the y-axis?
Just showing a technique that can be used in multiple scenario when other lines or axis are not available.
Did you do this in part design because it was the best way, or to show it could be done? I am still struggling to work out whether part design should only be used for simple parts.
People tend to use that the most and I knew you would get into a few challenges trying to complete the model. So thought it would a good example of mixing workbenchs. Part workbench is so much more flexible and as you say part design can fall down when a model gets to complex. I have a video on my channel regarding part vs part design which explains the reason why they exist and when to choose one over the other.
