Simple Groove drawing help

[britovsekmatic128]

Hello,  what is the best way to draw this groove with radius reliably, when only the total depth, width and radius are known with the vertical line being unkown lenght?

I have to draw a couple of diffrent versions with each having diffrent width, depth and radius.

Thanks!

Without one more dimension, the total linear length of the groove, you cannot reliably create the groove.

I feel like either yo answered your own question, or there is a subtilty to the question I don't understand

I think I understand the Q...Assuming symmetry it's not unknown it is defined. If its a problem then perhaps

Constrain the centre of the arc.

I'm sorry im new to this and english isnt my first language.
What im asking is if width is 22.9mm, total depth is 7.49mm and radius being R18.75mm what is the lenght of the vertical line?  I am only given the information for these 3 measurments and each version has diffrent width, lenght and radius. What is the best way to sketch this?

Thanks.

Yeah im trying with constrains but not 100% sure for the lenght of the vertical

ok.  the sketch I posted for you will do it then.  I've attached it with the values you supplied.  they can be changed as needed and will show the length of the resulting vertical lines.

@laughingcreek has the solution but I will give you a parametric model if you desire to see the results in a the Parameter Table as well as the model.  Change any bold values and the one indicated by the red arrow will report the end slot length.  Model attached.

@jhackney1972 @laughingcreek Thank you both! Made my life a lot easier!

@jhackney1972If i understand correctly, the formula for the radius ( 1 * 2 ) * [this is where i write the radius that i need? eg 18.75]

[jhackney1972]

I replaced the model.  It looks like your downloaded the one where I had used a Diameter instead of the Radius.  Download it again and the new one will have the Radius instead of the diameter.

@jhackney1972Can't thank you enough! You really went above and beyond!👍
