# Thread: Draw tangent circle ?

You changed the parameters of the original question and you call that being clear. I think not.

Are these homework assignments?

hahaha ok Rob but when your colleagues answer me i replay correct to 9.0015 to original question, just i make review of my question to get a digit, any way the meaning not in numbers the meaning in how the way to solve it. thanks for interest Rob ...

this is a engineer practice no more.

I can understand that point A is a tangent point, but at point B, the parabola cannot be tangential.

My understanding of a parabola is that it is asymptotic.

And the dimension at "I" should be more like 15.7. Perhaps you are not using enough decimal places.

Your AutoCAD can be accurate to 8 places of decimals, you only have to set the precision.

it can be like this: image below
if you can give me drawing template?

I would do that with pleasure, but first I would like to lean from you which is the reason of your question? I mean, for what you need the results for those two geometrical queries?

6. Take home test.

its just face me and thinking how to draw it, i want it with snap but cant if you can do it wth snap let me know

8. You already have the graphical solution courtesy of eldon. Do the sketch as per his instruction and choose tangent Osnap first on the small circle, second on the tangent line (above) and last on the big circle.

but when use tangent snap cant get fixed point, eldon get verticle line to help him to draw circle not snapping.

I just reproduced the solution eldon proposed and it is correct; also doen't imply any veritcal line. The point is to trick AutoCAD calculate the result using both the small circle and its tangent on given point, even the contact points are identical.
Please don't miss that when use the Tangent Osnap mode you don't have to pick a point, but rather select a part of a curve (when the tangent point will lay).
