Is the LEUL Horizontal Tail drawing correct and accurate?
I am tinkering about with CAD and thought drawing the LE would be a pretty good exercise and help me understand the plane a bit better. I got to the horizontal and ran into an issue. When I draw the tail using the dimensions from the drawing, it does NOT look right. Like really wonky.

sigh... ya'll are going to make me post pictures, aren't you?

Well.....Wonky is interesting, so , yes!

Okay, after a quick bit of work in a free 2D CAD (LibriCAD)
In the middle we have the original drawing.
On the left we have the CAD version of the Horizontal Tail using the dimensions given in the plans.
On the right we have the CAD version of the Horizontal Tail using dimensions taken from measuring the drawing.

The plans are not scale drawings. Measuring them will lead to frustration. I used the dimensions listed on my XL plans (similar) and my tailfeathers look fine.

Thank-you @Kamcoman77.
I don't have any issues with the dims in the drawing, it just cam out looking really different so I wanted to make sure I was doing things correctly.
Mostly, the CAD files will be used to help set up the tooling I will use.
I work in an airplane factory. Part of my job revolves around writing work instructions and getting tools made. It's possible I have been somewhat spoiled by 3D CATIA drawings. Which is, of course, one of the reasons I am drawn to the LEUL.
