Beginner questions - round edges in sketch

[julianH3MNS]

Hello guys, 

I am very very new to Fusion and only watched about 5h of tutorials about fusion. I hope I am in the right forum here to ask this kind of questions. So please don't judge me. I used to photoshop and illustrator so changing my thinking into the fusion and 3D modelling world is still in progress and will take a lot of time. 

I started my first project, where I want to create a clamp design for a power bank. 
The basic design is finished but one detail is not right. The inner space where the power bank will be put should be as fitting as possible. Since the PowerBank has round edges the inner square needs those kind of round edges. 
They are not perfectly round so a fillet won't do it. 

After trying for a while I couldn't figure it out. 

I have a couple of questions here: 

1. What would be the best way to get those round edges in the sketch now, as I finished most of the design? 

2. How would you design those round edges into the sketch from the beginning?

3. To know the exact "measurements" of the edge I probably would need a 3D Model of the actual Power bank right?

Please attach your model and the "Exact Dimensions" you desire in the corners.

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Edit the original sketch.  Do just one.

Add a 2 point spline.  Make it Tangent constrained to the straight lines.  Adjust end point position by sliding or dimension.  Adjust curve shape with one or both tangent handle length.

(Edited) Mirror (x 2) to the other corners

Hi,

I would strongly recommend that you do the embedded tutorials in the Fusion Documentation and also some of the

Self-Paced Learning to help you to learn fusion faster and better. They can be found here:

It is also much easier for the forum to help you if you attach your file AND a screenshot of what you want to achieve

and what the problem is. You can create a file to export like this:

Time spent on the tutorials and self paced learning will not be wasted. See RULES #0, #1 and #2 pinned to the forum

for more help.

Ok. What you have started with is certainly on the right track. You are using simple sketches and then using the tools

like fillet to model with. @davebYYPCU has made one suggestion on how to do this, another is if you have also

modeled the case that this clamps around, you can make the inside of your clamp bigger than it needs to be and then

use the case as a tool to do a combine cut operation. This means that the case becomes the cutting tool and you cut it

out exactly thew size you want.

In terms of how to fix this issue you have. The best way is to simply roll back the timeline to the original sketch. Edit

the sketch to how you want it. Move the timeline forward to the extrusion. Edit the extrusion so it gets the new

features. Move the timeline back to the end.

This is a common technique. The timeline is a very powerful tool and is useful to try things out or to fix issues you

find later down the track. It literally allows you to go back in time to before other operations were done to make

adjustments and when you move the timeline back the other operations will simply re-calculate if the changes have

affected them and move on. The danger of manipulating the timeline is that it can sometimes throw errors and break

your model so you need to either change it back, find another way, or sometimes simply force fusion to recalculate the

errors one at a time and they might clear themselves.

Cheers
