How to Edit Sketch

[Anonymous]

I started with a sketch (two circles to make a donut), Push/Pulled it, now I want to edit the size of the inner circle, how? I click on the sketch line, click on the timeline, click on the sketches in the list, nothing. I've also right clicked and can undo, move, delete, where's the edit? 

I've checked videos but the several I've watched haven't covered edit, just how to make it in the first place. I'm new, but things like this were so intuitive in Solidworks.

Hey Garnet,

Welcome to Fusion 360!  My guess is the visiblity of the sketch you created is turned off. Look to the left in the brouser and look for the sketches folder.  Make sure both the sketches light bulb and the sketch contained within the folder are both turned on (yellow is on and white is off). Let us know if that fixes it.

Also if you don't see a timeline in the bottom then you are in direct modelign mode and not parametric mode.  We support both.  In direct mode the sketch won't be parametrically linked to the extrusion you created.  This can be a very freeing thing, but if you're looking for a SWX style experience I'd model in parametric mode.  If it's turned off, you can turn it back on by right clicking on the top level assembly and selecting capture design history.

Let us know if that helps.

Best!

Mike

Thank you for the quick response, that's a lot of information, however it still doesn't tell me how to actually modify the dimension. The bulbs are all on and I have history at the bottom, but at this point I don't really care which process I'm in (I've used SW & SE), I'm fine with constraining the dimension of the solid part or the original sketch. 

When I right click on the timeline and select edit (which is showing up now but wasn't earlier) it puts me into sketch and shows the sketch lines, but not the dimensions. If I select Dimension from the drop down menu it won't allow me to dimension it as it then says it's overconstrained.

If I left or right click on the surface 'Dimension' isn't one of the options (I presume because I'm in historical mode?). So how do I edit the dimension of the inner face?

Thank you. 

Edit: Okay, there are three sketches, I'm not sure why, they don't highlight anything when I click on them, the first one highlights and the dimensions showed up and I can edit. I'm not sure what the other two sketches are, I've deleted them and nothing changed on the model.

Is it possible you've created more than one sketch?  If you've created a second sketch overtop of the first sketch then it will reference the other sketch but it won't allow you to add new dimensions to drive the geometry of that sketch.  Is that it?  Pic examples below.

If not, snap a screen shot of your screen and let's take a look.

Best,
Mike

For additional learning here's a pretty good video Patrick did with sketching.  It doesn't feature the newly added side panel for contraints but  the sketch and contraining behavior is the same.
