Actually this week’s assignment is very familiar to me. This week we were going to do some 2D and 3D design. At first, it supposes to be easy but it wasn’t. One of the points was to do parametric 3D design, the other one to use at list 2 programs. I chose fusion 360 for 3D modeling and Inkscape for 2D but I have tried some other programs as well. As the previous week,, this week’s assignment starts with watching tutorials, firstly I get used to Fusion 360.
I decided to design my final project, for that first of all I needed to install fusion. That was one of the simplest steps. After opening fusion I knew that first I need to create sketch (2D). I wanted drawing to be parametric for that, I had done my sketch parametric as well. For making design parametric in fusion I need to follow some simple steps, first open modify under menu and select parametric then write the name and dimension, after go to sketch and instead of writing numbers in area write the name of the parameter. Then I started simply sketching. I used the circle, rectangle, polyline, offset, mirror, etc. for the 2D sketch. after an houer I got used to it.
After I started doing 3d stuff. The first tool which I use was Extrood (which become the most useful 3d tool in this experience). After trying to work with this sketch I understand that I started from the wrong side and make a new sketch. And offset the rectangular and extrude it. For this project, I’m going to use a sheet of wood or MDF with thickness 18mm, that’s why offset it 18mm.
Then I need to make sells for the plate (3 sells). For that, I have o make a new sketch in the front face and again all of that is parametric. Do some offset and fillets in sketch then use press-pull to press them inside.
At that point, I already had the body and need to model the part where feed would be placed. For that, I create new component from the browser (browser is at the left side)then make a new sketch on the inside wall and extrude it.
The next step was modeling the pipes by which the feed would go to the plate. For that, I create a construction plane then sketch on it and extruded after I need to connect all three components(body, bunker, and pipes). To connect part I use extrude but in extrude menu change the direction of extrusion and operation
Finaly 2 component were the plates and cover here are the steps sketch, extrude, fillets.
Then I modeled the opening and closing valve which goes inside of pipes. To make that work some components are needed the main valve that which is 1mm smaller then inside diametr of pipe, shaft and stepper motor(its mpdel was downloaded from here ). Here are some screenshots.(unfortunately I haven't saved it).
The last thing to do was making the feeder look better, for that fusion have render workspace. For choosing the textures open appearance menu by pressing hotkey [A] . then I need to drow a logo for the modeled product to do that I tried 2 programs Inkscape, gimp and choose Inkscape because of its user-friendly interface and simply find tutorials faster. After I drawing the logo I imported it to fusion and here is what I got. Here is the result.
For resizing I used paint that was surprising for me how easy it is o do it in the paint(have tried gimp and Inkscape as well). I used solidworks as well and I think that some of the models which I would need in the following weeks I would model them using solid works .
This week was very interesting because I tried to use applications about which I haven’t even heard before. I understand how easily get used to new programs and work with them, how to do 3d modeling in the right way. Before this, I was using AutoCAD for 3d modeling and couldn’t change it to anything else because I got used to it too much now I’m interested in trying new programs. The most important goal of this week was using parametric modeling I haven’t tried that before but now I don’t think that would model without using parameters.
