Hello Everyone!

im new here, and i wanted to know how can i do this.

the basic idea is using a PNG image of the bike itself, and draw some lines representing elements of the bike geometry, by example, seatube lengt, i draw i line between the center of the crank and the top of the seatube.

and after doiung that, inserting some know values in my models so that it gives me the exact lengt and values of all the lines i draw.

following with the example lets say that i drew a line to know the effective toptube length, from the center of the saddle to the top of the stem, but i dont really know what is the exact dimension of this, but since i know the dimension of the seatube, i cant use it to determine everyting else.
this can also help me find out the values of head angle, stack, reach, and all the other measurements related to bike geometry just by using an image of the bike and a know value.

i know there must be a way to do this but i couldnt figure it out by myself so i opted to ask for help here.

Thanks in advance!
