Week 2: Computer-Aided Design¶
Small animal portable house with Corel Draw¶
We entered Corel Draw and designed the portable house for small animals
We go to the color palette section and choose the light blue color
We click on text to be able to write the title of the project
The result we obtain is:
We enter rectangular tool to create the house
We duplicate the square to make the other part of the house
We create your tires
Creating the divisions with a 2 point line
We create the containers
Creating the portable house handles
We enter the image of the guinea pig
We increase the food container
Portable Small Animal House with Inkscape¶
STEP 1: We click on the bezier tool
STEP 2: We frame a square to make the cage for the smaller animal
STEP 3: We paint the area with the fill tool, choose the color and replicate the graphic
STEP 4: With the bezier tool I make the traces of the cage
STEP 5: We import the image of the guinea pig to the work table
STEP 6: We complete the work with circles and color
STEP 7: The cage is left this way
Comparing Corel Draw with Inkscape¶
The results are similar. Personally, I like Corel Draw better because of the simplicity of its tools
Using GIMP¶
GIMP is a Free Software application covered by the General Public License version 3 (GPL) [GPL]. The GPL gives users the freedom to access and modify the source code from which programs are built.
We open the GIMP software
Now to saturate the image, for that we go to color and saturation
We set the scale to 0 and accept
We are going to colors and curves
We look for the color white at point A and at point B we look for the color black
Create a transparency layer
We verify that transparency was created
Select a brush on arrow A, choose the sharpest color on arrow B, set the brush size to the smallest one on arrow C, and set the opacity to 75% on arrow C.
We begin to outline the entire image with the brush
We add a white layer
We put the white layer under the transparent layer
At the end it looks like this
Rasterize in Photoshop¶
Open Photoshop and write a text like Fab Lab Pasco
Enter filter and focus edges
We get a message asking us to convert to a smart object and rasterize
Now that we have rasterized we can put effects on the text since now it is not a vector but an image and again we put a filter and focus
Now we can edit the image, for example, we can make a soft focus and thus edit the image further.
Chess board made with onshape¶
we change the configuration to millimeters
We choose millimeters
Right click and choose new sketch
We click on line on arrow A then in the sketch we begin to outline the lines on arrow B and with the dimension command on arrow B we can measure the distance from point to point there we write 5 millimeters.
We continue moving forward if we wish at the end we can just put the measurements of 5 millimeters
When we finish with the dimension tool we can start measuring from point to point that is 5 millimeters.
We add color by right clicking and choose to edit appearance of sketches
We choose the color we want
The image looks like this
We make 6 types of square models and begin to assemble 64 squares in a row to make the chessboard
Now we are going to assemble on arrow A and then enter the chess parts one by one to assemble.
Entering one by one it looks like this
we begin to join the pieces or assemble them one by one and change the color of the squares
When we click on the image, some directional arrows are activated and we move in the direction we want
When we finish joining all the pieces, the chessboard is taking shape
We put it in elevation view and have it ready to be exported and printed on a 3D printer.
When exporting it has to be in STL file type so that Ultimaker cure reads it and converts it to a gcode file
Chess board made with tinkercad¶
STEP 1: We click on the cube and drag it into the work box
STEP 2: The squares are 20 mm so the thickness has to be 2 mm
STEP 3: Duplicate with the duplicate tool on arrow 1 then set the thickness to 1 mm on arrow 2 and change the color with arrow 3
STEP 4: Duplicate and start forming the chess board
STEP 5: Complete the board in total with 64 squares, some of them 2 millimeters and others 1 millimete
STEP 6: The difference of 2 millimeters and 1 millimeter is shown
Other related works¶
Let’s watch the video of the creation of materials with Onshape¶
Creating chair with Sketchchair¶
We create with the brush command the chair but not the legs
We create with the leg command the legs of the chairs
We play and verify how comfortable the silhouette can si
we can rotate to be able to see how the chair is looking
with the select button we can modify the seat for the comfort of the client
In the upper right part, click on make it to go to the model and we can see how the plans are to be able to print
we export to pdf and it comes out like this
We made the video of the creation of the chair with SketchChair¶
We make an ice cream with Tinkercad¶
We open the program Tinkercad
we click on the cone and drag it to the artboard
We make a 180 degree turn
We put it in top view and enter the circle
We translate the circle so that it intersects the cone
we can climb the circle up
we create 2 small circles for his eyes
we enter the curved roof icon for the mouth of the ice cream
let’s watch the video of the ice cream creation with Tinkercad¶
Comparison of GIMP with Photoshop¶
With the GIMP software I have been able to work with vectors and there I cannot use a filter but using Photoshop I use a vector and I rasterize it to the image and I can put a filter on it and it works excellent

Comparing Onshape with Tinkercad¶
When making the chess boards in the 2 programs, it is observed that in the tinkercad software it is more intuitive, unlike onshape, you can do more detailed work. In the end, I loved using the 2 software
