Scaling plans up and down

Hi All, I have a Twotrees TTS-10 Machine and using Lightburn software. Latest version.
My question is how to scale down a rc plane drawing from fullsize to a smaller version.
My plan has a 1573mm wingspan. I would like to convert the whole plan to suit a 1430mm wingspan, is there an easy way to do this.
Thanks in advance.
Paul.

What format is it in?

You can scale things easily. However, if there are parts that fit into each other a direct scale likely won’t work … unless you can scale the wood thickness down also.

It usually shows up when things such as a spar that need to go through a rib of the wing.

What you end up with is a 2d type drawing of a 3d object and you can’t resize all of the dimensions.

Hi Jack, Thanks for your quick response, can you describe the procedure for me as i have not done this before.

Thanks for your reply, I use PNG.

Lock the aspect ratio button and type the desired change in the % field, plus (or minus).
For simpler constructions, you can use the resize slots function for fingerjoints afterwards.

Thanks for your reply, i will try tomorrow.
