# Thread: Draw tangent circle ?

1. Registered forum members do not see this ad.

To get a circle of radius 9 exactly, the offset should be 5.39227909

2. yes my autocad just 4 precision. can you give me your way in detail you just make vertical line but how you get the second tangent point ?

3. Issammm, your original question was not stated correctly. If you had stated that the radius, Rx, was to be 9 and the offset was the variable, you would have been given a solution that was quite easy. Draw the circle with the TTR option, selecting the two circles and specifying 9 for the radius.

my question is OK, eldon give me correct answers in too accurate.
jst eldon give us more precision than needed.
the Rx = 9 for case 5.3923

regards to all

5. Issammm, I gave you above the radius, calculated as per your sketch, with 8 decimals and a solution to use it; isn't that enough for your sketch?

6. How can it be when you are changing the value, 5.4152, to a variable and assigning a value where you had a variable, Rx?

Seems that you were asked for the radius in the first place!

MSasu you are completely correct.(I hope you explain how you got your answer)

Rob i hope you give me correct answer next time all my replay was clear.

if you want more challenge draw this and find all arcs length.

9. It seems that there are not enough figured dimensions. For example, where is G? Is it at the end of a semicircle?

One could guess, but that might not be sufficiently accurate for you

points B till I are tangents points except A is a vertex, think well you will get it.
