Dew Point Monitoring System for FogCatchers ----------------

Week 2: Computer Aided Design

 

I tried some of the tools:

-Sketchup

-Inventor

-Rhino

-Thinkercad

-Inkscape

-Fusion 360

 

In all of them I did some exercises, but I did my first ideas of the design of my project, with Sketchup

 

 

Sketchup

 

I was thinking that the Air Capturing System, could be implemented as an decorative structure, here some ideas ilustrated with Sketch:

 

 

The structure catch fog form the air and the shape allows to be stable.

 

 

 

The previous form is a good way to get the area maximized in a volume,to be in contact with the air.

 

Inventor

Not as easy to use as Sketchup, has lots of options and icons in the pannel. I tried some basic features like revolv, mirror, sweep.

 

Rhino

 

Very good experience with Rhino, it has tutorials and support documentation that helps.

 

Somethink that helps a lot is the F1 key, from the command field, it takes me to an online help, related with the command.

Some other practices:

 

And there is an interesting tool food4Rhino, wich have many apps for Rhino and Grasshopper

Thinkercad

Very easy to use. In my experience, Its very useful to work with Helpers, it defines a new plane, in wich is very easy to put new objects.

I made those with boxes and cylinders, using the Workplane on Helpers. I did this:

 

Some other using Tinkercad Shape Generators, and duplicate option

In ThinkerCAD, the files are in the cloud. They are in my account:

 

Inkscape

Between its functionality, Inkscape allows to vectorize one bitmap picture. I tried with the option Path / Trace Bitmap. It generates a svg file.

 

Using the Path / Pixelart option, applied to a groupal picture, the result is this

 

Update: Fusion 360

 

 

With Fusion 360 you can create designs with a  very easy-to-use, powerful industrial and mechanical design. It connects your entire product development process in a single cloud-based platform. Main big applications are:

  • DESIGN allows to quick iterate on design ideas with sculpting tools to explore form and modeling tools to create finishing features. Solid modeling, Parametric Modeling and Mesh Modeling.
  • ENGINEER AND SIMULATE: Test fit and motion, perform simulations, create assemblies, make photorealistic renderings and animations.
  • CAM Create toolpaths to machine your components or use the 3D printing workflow to create a prototype.

Once you launch Fusion 360

 

Clicking on nine squares you can see My Recent Data, where you can see all designs

 

Click on Create Sketch

 

 

Open the Sketch option, you have all those options, like Rectangle, Circle, Text, etc etc. All those are to work on a 2D plane.

 

 

I will design some 2D object. I click on "2 Point Rectangle"

 

 

You can see now the measurement of each side

 

 

Then I choose 2 Pint Circle

 

 

 

I choose two points of the sides of the rectangle

 

 

You can use the Trim option

 

 

While the cursor goes on the elements of the draw, some gets red. If you click there, that line will be erased.

 

The last segment to be erased

 

 

 

Using the Center / Center Circle Diameter

When the measurement appear, you can write there

 

 

There you can see the constraints, in this case the paralelism between sides. You can erase them whenever you want.

 

 

 

Using Center to Center Slot

 

 

Then I used the Circular Pattern

 

 

First select the objects and then select the center point.

In quantity, you can write the number of copies to reproduce.

 

 

 

And to clean the aspect, use Trim option

 

The resulting 2D object

 

 

Fusion 360: Transforming in a 3D Object

 

First click on Stop Sketch. Doing this, you are not any more in a 2D word.

 

Use the Extrude option

 

 

Select the profile and put the distance to extrude

 

 

 

 

Select the Orbit option, and you will see this
