Not sure if I’m going to use the right English words to describe what I’m looking for.
My intention is to draw a circle circumscribed and tangent to other two.
Let’s suppose I have a circle called A and another one called B.
I’d like to know how I can find
the center of the arc I drew in “red/pink”
the tangent points of the big circle on A and B.
I know TIG developed an awesome extension called True Tangents, not sure if it can help in this situation but I wasn’t able to use it to solve this situation.
I know little maths and nothing about architecture, but all kind of help will be appreciate.
The red arc can be any radius greater than half of the sum of the distance between the centers of A and B, and Arad+ Brad
The minimum value is a circle which is tangential with A and B and is centered on a line drawn from A to B, offset appropriately.
The maximum radius [infinity] results in an arc than is effectively a straight line tangentially to A and B.
See the image for the need for an Xrad for an A & B tangential arc, and finding it’s center.
Awesome explanation TIG, I understood that I need to know the diameter or the center.
The radius is on the blueprint, but I didn’t realized at first.
Thank you.
