I’m always getting the sizes wrong. It’s too big and I don’t really know how to measure things like this and how to get it exactly precise for a type of panel like this. @WillAdams @Tod1d. For the other projects that I had that you guys helped in I actually made those projects well. This one my problem is just knowing how to get the size correctly. sometimes in the grid I go to off during designing
My solution for complex projects such as this is to start by cutting a prototype in some inexpensive material, then check the dimensions of the prototype, and iterate until it is sufficiently dialed in that risking a piece of expensive stock is not really a risk.

I’m using PVC. I’m gonna try again, but the measurements is hard for me.
Turn it around?
Make a negative of the design, then try to drop it in place — adjust where it doesn’t fit until it does?
I’m guessing it’s the outside profile, and maybe the screw holes that you need.
The first question is, what precision measurement tools do you have?
I would set this up like one of the previous panels with a contractors square, or XY fences on the machine, and butt the lower left corner into the square. Now measure perpendicular to the square for your dimensions.
I use a machinist’s scale, with graduations at 0.020"
Tracing on graph paper is also an option. Use a good sharp pencil at an angle to get a really tight line around the part…
To use the “fewer measurements & tracing the image” method we used before, capture these dimensions, then set the image as your background & scale it to fit. Also measure the centers of the screw holes…

Rey have you tried tracing the image to help get the correct size.
I have used this method to get sizing correct on several projects. I you have and did not get good results let me know. I will work on tips and instructions today and post as soon as I have them ready.
What will help is a clean picture laid out like this one but without all the black lines and writing on the side. I tried using this image to trace but the extra lines makes it harder to trace and edit.

What I’ve been doing as of recently, I get it as close to the panel and then I cut the parts I get wrong on a router.
I have tried to import the images from here and also to trace the image into C3D and with all the black lines it adds a lot of editing to the process and distorts some of the items and lines too much to get a good tracing. Even after adjusting the threshold and threshold angle it requires a large amount of editing.

You’d need to edit the image if you’re going to trace it. Erase all the impertinent stuff, and edit the contrast between the background & the panel.
Better to import it as a background image & draw the shape manually. The image still needs to be squared up & scaled to the dimensions.
It’s also obviously not taken from a point directly above the center of the part. If it’s too big to scan, it’s best to get the camera lens perfectly centered, and as far from the object as possible.
Here’s the image cleaned up
It still needs a bunch of tweaking to smooth it out. I deleted a bunch of nodes to get it smooth.
It’s easy edits, just deleting nodes & smoothing them (S key toggles between hard (square node) and smooth (round node)).

You’ll need to scale it to the right size. & maybe adjust some nodes to fit the actual sizes.
