How do I make this circles a smooth one - equivalent of coradial feauture in solidworks ?

[user35999]

Hello how do I make this sketch of disjointed line segments into a smooth circle. I retrieved the sketch/drawing from a file. Any help will be great appreciated on what constrain or tricks I might be able to use. I know solidworks has the coradial constraint - not sure what is the equivalence for fusion. Please find pictures below

1- This is the Inventor forum, not Fusion's.
2- You have not attached or embedded any pictures in your post.
3- You could attach the sketch, file, or original source you used for this drawing to make things clearer and possible to test.

4- If you have something similar to the below, you could create a new circle and use "Tangent" constraints to hopefully approximate the surrounding lines:

OBS: keep in mind only a few "lines" can be tangent to your circle simultaneously (3 in my example below), assuming the lines are all locked (constrain-locked or projected-locked).

Hi! I believe for this particular case, Fusion's workflow is similar to Inventor's. I don't think there is a Coradial constraint. You need to add tangent constraints between the circle and the lines.

Many thanks!
