I'm trying to learn Fusion 360 on my own, and it's very frustrating not having a mentor around to guide me.
When I draw a circle, (Center point, Diameter), I would like to be able to just type in the X,Y center location, but I see no X,Y display anywhere.
HELP!!!
Why isn't there an X,Y display somewhere that corresponds to the mouse pointer location?
This is driving me nuts!!
GGRRRR.....

Make a point at zero and dimension the circle relative to that.
YouTube has a lot of videos that cover the basics. Lars Christensen and John Saunders are great at explaining different things related to Fusion 360.

I'm not sure if it's possible to do what you want since the mouse position is relative to your view. Fusion (or any CAD package) would not know what the X and Y position relates to. Drawing your circle and dimensioning it to known features is pretty much your only option for an accurate model unless you use construction geometry.

And believe me, I understand your frustration. It took a long time to get comfortable with Fusion, but now I love it.

Russ you cant If you start your sketch from the origin that's your zero.

You don't even need to put in dimensions to you feel like doing it, that's parametric design for ya.

[RussMachine]

So if I sketch a rectangle, and the bottom left corner is origin, technically that would be X0,Y0.
If I want to draw a 1/2" circle at X.500, and Y .375, why can't I tell Fusion, X.5<enter>, comma, Y.375<enter> <tab>, Dia .500<enter>
Sketching construction lines and points seems like a real waste of time

[precisionmetal]

It's a different beast, Russ. I'm guessing you come from a CAD program that worked that way, but this one doesn't.

I too, came from something VERY different from Fusion, and had to "re-learn" many things, but now after a bit over 6 months, I can model just about as quickly in Fusion as I did in the CAD program I used for the past 15-20 years.

The first rung of the ladder is always the most awkward... after that the learning becomes easier and easier. Hang in there! :-)

Russ you would put a diamention in from the origin to the center of the circle if the center of the circle was required to be at x.5 y.375 that would be .5 to the right of the origin .375 above the origin, then in cam the origin would be sitting in the same places same with the hole.

Yes it sounds bonkers and completely stupid but once you get the idea it's just as fast or faster you even can do designs in metric and inch at the same time with inch you can use decimal or fractions as all that matters is the unit symbol in for inch 1/4 for fraction even ft for foot metric is mm, cm, m there are all the other types of measurements you can do as well.

A rough visual for you Russ

When described like that, it makes sense for the software to do exactly what you are saying, but then it would require all of your sketches to start with the origin being your zero, zero. That's not always the case.

Because parametric solid modelers don't work like 2D CAD programs.
It takes me at least 5x longer to do something in a program like Fusion or Solidworks than I can do it in AutoCAD. Mainly due to the sketching.

[dharmic]

Nothing would take me back to AutoCAD for 3d modelling. Been there, done that, have the scars of self harm that resulted.

But jeez I miss being able to l0,0<cr>40,60.9<cr> and so on in AutoCAD for 2d stuff. If you knew what you wanted, it was so damned fast!

[ger21]

Imagine if Fusion's Sketches let you draw like in AutoCAD. It would be 10x faster.

But would it really? You would still have to go back and dimension everything after it's drawn.

Fusion is slow at sketching but I don't think this is why. It's slow because the right click menu isn't optimized for efficient sketching. It takes too many clicks and mouse movements to get to the commands you want.

For someone like me that uses AutoCAD every day, yes. Because you can draw everything exactly how you want it before you add the dimensions, so when you do add the dimensions, or constraints, everything is already the right size, so it's quicker.

I was working in Fusion the other day, and what I found to be really slow, was trimming lines.

Ahh, now this is interesting. You're making the assumption that you know exactly what the design should be (including dimensions and constraints) before you start drawing. If that's the case then it may very well be faster because it's essentially just being used as a drafting tool and not a design tool. For raw 2D sketching speed it would be tough to beat AutoCAD. (Although I don't think it's quite a fair comparison because AutoCAD is not parametric, and parametric modeling by its very nature has more overhead associated with it because the creation of an entity and the definition of it's location are separate acts)

But the real power of parametric modelling comes when you don't know all the details of what it is you're designing. You know the general shape but not the exact locations and dimensions of things. So you put in a best guess up front and then come back later to change it when you know for sure.


To the original point about pointer location; there really ought to be a display somewhere that shows the coordinates of the mouse pointer relative to the origin. That's such a basic thing that would be easy to do and would be quite useful, especially with sketch snapping to the grid turned on.

I was working in Fusion the other day, and what I found to be really slow, was trimming lines.

Trimming of lines is something I find rather tedious in general, even in Solidworks which is my design tool of choice. In my experience if you have to do a lot of sketch trimming, you are probably relying too much on sketching and aren't making the best use of the 3D modeling tools. Sometimes there's no other choice but generally I try to avoid it.

Yes and No. It's still faster for me to stretch and trim, or redraw in AutoCAD than sketching in a parametric modeller, at least for me.

Actually it has had parametrics for at least 5 years, but they are optional. (I've never used them) Using them would slow things down somewhat.

It had a lot to do with the specific part I was making. There may have been a better way to do it, but I was too far invested to change course.

[daniellyall]

cygnus x-1 bottom right corner when you click on a sketch point the relative position is shown, It's not what the OP wants it's about 1/4.

That's helpful if you've already placed your sketch entity, but not before then, which is what the OP is looking for.

triming in 3d parametric software is a nono. try using splitting instead, I read/watched several tutorial and trimming is not a way to go. designing in 3d is way faster when get the hang of it...

The new August update that I just got would have saved all the trimming I did the other day. There's are new arc slot sketch features, which is what I was doing the other day.
