I’m having a mental block here. I am trying to create some replacement pieces for my grandkid’s wooden train tracks. Modeling the curved sections is giving me a fit. I modeled the full diameter of the track to get the right spacing between the features. Now what I would like to do is cut out a 1/8 of a circle arc. I can’t really figure out what the right approach should be.
Maybe I am using the wrong approach to start with? I’ve attached the CC file so you can see what I am doing.
Thank you
I slightly changes the size of the stock, then moved the existing features so they center on the grid. I added a small circle so I can see where the center is. Group the curves so they act as a single entity.
Then I drew in a horizontal line, starting at the center. Duplicate, rotate -45 deg, move to center. Draw a third line to connect those, then use Join Vectors to create a triangle.
Now you can use Boolean Intersection to get the arc you need. You will probably have to draw in some more geometry so you can both pocket the tracks and cut the item out.
Thank you! That is exactly what I was trying to do. I was a several logical steps away from this approach. I am not sure I would have actually got there
I went through the exercise of following your instructions step by step to duplicate the result. So now I will know what to do in the future when confronted with this sort of design challenge.
After using Trim Vectors you will need to close the paths.
I would also recommend using two separate lines at each end, one for trimming to length, the other for extending the channel for the rounded form beyond the end.
Thanks for all of the help. I am a lot more familiar with the capabilities of carbide create. I was able to work through the design process and create something the turned out well. I have attached the file if anyone is interested. curved track section 2.c2d (156 KB)
