create three radius together

[hdude]

I have no training in this software. I've just been kind of thrown into it at work, luckily it is just 2D stuff we draw and mostly pretty basic. I cannot figure out how to create three different radius' in a row. I made a hand drawn (poorly) example of what I need to do. I am at home right now, so I don't have access to autocad right now.

 

I have attached a .jpg of my windows paint sketch of what I am looking to do, but I have now idea how to do it. I can get the radius of the left most and right most radius, but have no idea how to get the middle one.

 

Hopefully someone can give me a clue how to do this.

Draw a circle R=72

Draw a line from center of circle L=20 in the direction where you want tangency

Move line from 2nd endpoint to Appint of line and circle

Draw circle R=20 from !st endpoint of line

Draw line from center of 72R circle L=12 in the direction where you want tangency

Move line from 1st endpoint of line to Appint of line and 72R circle

Draw circle R=12 from 2nd endpoint if line R=12

Erase lines, trim/break circles as necessary

 

There might be an easier way, but this is the first to come to mind

 

You might want to try using a polyline with the Arc and radius options

Simple use circle TTR then trim

 

It sounds like you have found the bug in the fillet command if you have two circles or arcs and want to add a third autocad often gives you a S bend as an answer

Draw 3 arcs while snaping to the end of each with object snap then enter the radius in properties.

you can define the arc length of each as well.
