Help creating turns in a marble race track

LightBurn Software Questions
1

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

2

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.

5

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.

6

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.

11

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.

15

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

16

Very nice tutorial and use case.

17

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

Cool, I look forward to seeing it in action.
