Simple question on placing a circle

[Smokeys]

I'm surprised I haven't had to do this until now, but I need to place a circle at a specific coordinate, say X=1.75 and Y=2.25.   What I have been doing is creating a couple construction lines with dimension and placing the circle at the intersection.   This seems clumsy.   Is there a better way?

Hi Kevin,

There are 2 ways in which you can do this the first option is, if you know the exact coordinates then you can start the Circle command, when it asks to specify the start point or center point you can type the X and Y value in using a comma to seperate X and Y and then enter and then continue with the Circle commands prompts, typing in the radius or diameter depending on what option you chose.

The other option is if you have an object and you know the circle needs to be a specific X and Y value from that point then you can use the ID Point command. How this works:

1. Type ID and enter
2. Click on the point that you want as a reference - it will save the coordinates
3. immediately after choosing the reference/ ID point start the Circle command
4. When it pompts to specify start point, type the "@" sign and the X and Y value
5. Continue with the circle command.

Please let me know if you come right.

Hi Kevin,

Do you need construction lines for particular reason? If not I think that the easiest way how to position a circle to specific coordinates is to dimension the circle against the Origin Point without construction lines. See attached video.

I tried this "There are 2 ways in which you can do this the first option is, if you know the exact coordinates then you can start the Circle command, when it asks to specify the start point or center point you can type the X and Y value in using a comma to separate X and Y and then enter".  It doesn't accept anything other than clicking to place the center.

@Smokeys it does not matter one bit in fusion where you stick the circle, you can place a circle on the sketch where ever and just dimension it into where you wont it.

saying places circle here does not quite make it parametric.

if what it is attached to get's moved and you wont the circle to move with what it is attached to it wont be where you wont it to be, (you can move everything together using the move command, but the circle is in a new position )

it make's things easier if you just dimension everything in to lock it down to where you wont it to be. using construction lines is just one way to do it.

have a look at the screen cast you will see I dimension the circle first then dimension the rectangle the circle does not move until I change the dimensions for where the circle is to be.

you can sketch a part out with just ruffly placing the line's circle's what ever. then go back and dimension everything in to where you wont it to be.

it is one off the fusion things that make's it a bit different to other programs and it get's people quite confused

here is another example where I randomly place stuff then lock it down with dimensions, everything turns white so you can't move it using the move command, but you can move stuff using the dimensions.
