Help creating turns in a marble race track

I need help learning how to create the turns in my track so the track stays evenly spaced. The inside versus the outside. How do I do this? Help

A picture showing what you’re working on and what you’re attempting would be helpful, but my first thought would be use the offset tool.

ok.

I need to divide this into 8th’s and 1/4s I also need to create slots around the edges for sides

I need to make these. One is a single track and the FI Grand Prix will have the multi track

I want a tighter turning radius though but the same otherwise.

I did that. It seemed to work. Now I need to figure out how to place the slots around the edge. Something to do with the array tool but I’m lost.

OK, so I’m assuming your end goal is something like this.


Let me get tomy other computer and I’ll make something that should help you.

I made a quick video explaining one way to get your 1/8 & 1/4 pieces. Getting your slots spaced around the perimiter and matching on your guardrails is a little more difficult. I would start with the circular array tool using the crosshairs as your center point and experiment with settings.

Wow! That’s exactly what I’m trying to do. Thank you. This is a great way to learn the software too. Thank you so much!

Glad I was able to help.

I did it! Thanks. Now I have one more request, how can I add the guardrail slots around the edge? I’ve failed epically for half the day trying to use the circle array using the partial circle track pieces.

Alright, I made another video for you. I just came up with this method, so not sure it will be totally successful, but give it a try. I would probably reduce the number of slots on the inner circle, but that’s up to you. Happy tinkering.

Thanks Tim. This will help more people than me, I owe you a cold one!

I ended up trying different ways yesterday, but I was going about it all wrong. I didn’t have the center circle. I never thought about the way you did it to get the guide lines for the slots either. I was so frustrated… Again, thank you. You should start a YouTube channel. As a professional teacher, you are in the same league as me if you were in the classroom. It’s a gift and you have it.

I saw the picture of the track you you posted. I tried to buy cutting plans from the man that makes those pieces but he only sells the parts. I don’t want to buy the parts when I can make them myself. And I can create any design I want now.

Your logic is correct. One problem is that when you use the offset command, it adds a fragment line at the end of arcs that you didn’t notice when you were selecting the lengths of the arc. About the 5.09 mark in the 2nd video.

I see it. Mike, be sure to check that all your line segments are accounted for when sizing your guardrails.

I did after they didn’t work. They work now. Thanks
I’m cutting and building this track today as I write this.

It’s a little hard to see but this is what I ended up creating. I’ve since modified the sections and rails to fit. I couldn’t have done this without your help. I’ll post a video of the marble racetrack when it’s assembled
. Thank you.
Mike
