Is there a way to sort of “knock the edge off” in advance using editing tools prior to slicing and printing?
The particular example is I am making a case for an Adafruit microcontroller. Square box with access holes on top and sides. Flat bottom with all four sides perpendicular to the build plate.
That edge is very pronounced I guess is the way to describe it. Not a defect in any way. More a tribute to the accuracy of a P1S.
It is also something that I find myself having to make a few passes over each side with a woodworking card scrapers similar to these ( Blue Spruce Scrapers ). Works great but was wondering if I could accomplish the same effect doing something along the lines of a very small fillet or chamfer in Fusion. Card scrapers do a good job, especially if you have used a brim, but they leave these shavings that are like as thin and thinner than human hair that get everywhere.
Fusion has tools to easily add fillets or chamfers; it’s usually my finishing step. Chamfers print a little more cleanly on the bottom edges than a rounded fillet.
Right-click an edge or face, select fillet or chamfer, drag the arrow to adjust size, or type a value. Ctrl+click to add more edges.
This video and this one about using fillets can provide more detail.
Card scrapers work OK, but a deburring tool can be easier to use on small parts and in tight corners.
I did the Fusion chamfer way. I wanted to make sure that there was not something I was not aware of. I am just climbing up the Fusion learning curve and I have not yet mastered all of Fusions shortcuts. For example, selecting each section one by one of a large radius as shown in this picture is a pain.
I have a deburring tool and the actual blade rotating in the handle have caused me to gouge some of the edges which won’t work.
Try rotating the model so that you can see the bottom. From the Solids menu, select Modify-Chamfer, click the bottom face, and enter a value. That should chamfer all the edges of that face.
I have no idea how you ended up with so many faces on that curved corner. I would expect a single smooth curve.
The tutorials that helped me understand the basics as a Fusion beginner were YouTube videos by Product Design Online. There are a couple of versions of Learn Fusion in 30 Days, but even the older videos are still relevant. I found that hitting pause and repeating the steps in Fusion myself really helps the lessons sink in.
I find that I can control the deburring tool best if I push it away rather than pulling, think skew cut, and let the rounded tip ride on an adjacent surface. It does take some practice (a good use for failed prints).
All those segments are pretty typical of models I import from Printables or Makerworld. In one respect it has some benefits because in lots if not just about all of the models I print, there is going to be a fair amount of deconstruction and reconstructions.
For example to use my picture and yours. If I go through and delete (deconstruct) every face, at the end of the deletions I will have the underlying square corner that the original creator put the radius on. I can turn around and do a fillet on that same corner and the result will be like your images with one long radius segment.
For me, I have found that it is easier for me to measure and do things like extrude using flat square/rectangular surfaces then come back at the very end and put things like fillets on.
The picture I took a clip of is for a microcontroller case.
The microcontroller I have is an Adafruit product. For all practical purposes, a case for that microcontroller does not exist. The PCB footprint is the same as an Arduino Uno but that is about it. The Adafruit controller has a bunch of built in ports that the Arduino doe not have and for the couple that they both have, the ports, connectors, switches/buttons are in different locations.
So I retained the basic PCB footprint and square shape of the case and lots of deconstruction and reconstruction.
My question was more “Is there a way to put a fillet on this already curved but multi-faced curve, without having to select each faces edge, one by one.” and not “just put a fillet on it” because I suspect a radius tool is lurking in Fusion somewhere. I just have not found it.
Plus I know I have not begun to tap Fusions full capabilities so lots of ways to do things in Fusion I’m just not aware of.
If you are modifying meshes in Fusion by editing the triangles, you have much more patience than I do. If I want to change an STL or other mesh model, I either reverse-engineer it from scratch using my own sketches or load the mesh and trace it.
This video was made with an older version of Fusion, so I had to Google some of the commands to find their current names and locations, but the methods still work very well.
