you say arcs but what about of the other lines/curves... ? 19.8 and 92...they were in the start figure ?
They don't change ? So it's drawing under constraint ?
Better if you send your start piece! :)

Thank you so much for your generosity for what I asked you gave me your solution.

I don't have words to say but THANK YOU so much. You are a good teacher indeed.

Where it's said on the first post that the 2 Arcs circles must be tangent ? :)
Without more infos...there are an infinite number of solutions! :)

Hi RayCAD1962,

Do not mention it :-) I just shared with you what I knew.

However, as PILOU says, you should be more specific with constraints you want. Otherwise there would be number of possibilities (sometimes infinite)

I like to share this YouTube video from where I so these changing of dimensions with easy method that I like to see it in 3Dmoi if it is possible.

Follow the video and you will see what I am talking about especially when changing the values of each arc and lines too.

Your method is helpful but this is more easy to be used when you need it.

Hope you understand what I am looking for.

Thanks again both of you.
