After couple of weeks of work, I’ve finally cracked surface modelling with Fusion360 (a bit)
Here’s a bit of a step by step in creating your very own f1 Key! This is a very brief summary of what I should have done if starting from scratch, I’ve left out the trials, errors and headbanging……….
Photograph a keyboard from the side, import it into Fusion as a canvas, scale it, create a sketch and draw around the keys……….
Add convex curves to tops of sketches (i’ve used 0.4mm for the indented part), Extrude out for a key length – just over 15mm here
Draw another sketch on the rear of the extrusion with a curve (three point curve – centre point is 0.4mm down from the top) – extend the sketch upwards a little over the key
Extrude ‘n cut – This gives us our key taper. You need to extend above the key as the rear is on an angle – extruding a cut will miss the far end of the key
Make sure to draw construction lines at the 1/2 way points for each sketch
Add another sketch to the top of the key surface. by projecting the bottom ‘upwards’ and the top into the sketch. Add some fillets to round off the edges, then create an offset inwards for the thickness of the future shell (i’m using 0.8mm here)
Create an offset plane 1/2 way along the key and then a new sketch – project the side sketch into the new plane. Ensure the ‘curve’ part intersects the top sketch
Create a new sketch on the bottom of the key body. Hide the original extruded body and go to the surface tab – surface modelling workspace
Create a new sketch some lofts from the bottom to the top key curves as shown
Do for all 8 edges and you’ll have this………..
Re-show the original body, cut off the curve bit to create a flat plane. Create another sketch on the front of the key as shown below. mark the midpoint and create another curve at the top
Repeat for all sides – Now you’ll have curves at the top of 4 sloped sketches, one on each side
Create a Patch – This will follow the curves at the top of each of the sides……
Create another patch at the bottom of the key………..
Now you have a nice, shiny solid body to play with!
Run a fillet along the sharp top edge
Find some text matching the F Keys, Sketch and extrude it ‘into’ the key
Then have fun with the local environments in the render module! It’s in a snowy scene because, for me, this is like Christmas 🙂
Loads left to do still, The fonts are probably going to take the most time now. Have ordered a few batches of switches in <£12 batches to pass comfortably through customs!……
