Assignment:
- In week 02, the task was left, which consists of: Modeling (raster, vector, 2D, 3D, rendering, animating, simulating,...), as well as proposing a possible final project, compressing images, videos, and publishing a description with 2D and 3D design files.
2D design
2D Raster: In this activity, I had to research rasters to complete the assignment. The concept of a raster is a "method for creating two-dimensional images from pixels." With this approach, it is possible to create lines and polylines from raster images, and these images can also be vectorized. For this project, I will use GIMP to create the 2D design.
Photoshop y GIMP
In this case I am going to install GIMP and also Photoshop in order to Model (raster, vector, 2D, 3D, render, animate, simulate) so I started the download process, then I proceeded to use the respective commands for each software.
Step 1
In step 1 I proceed to download the GIMP software
Step 2
In step 3 I proceed to install the GIMP software
Step 3
Completing the installation of GIMP
Step 4
Now you can see the simulation screen with its respective commands.
Step 5
Now imports downloaded images
Step 6
FHOTOSHOP: Now I have performed the same procedure with the fhotoshop software which is similar to GIMP
Step 1
In this case we are going to work with the Solid Work software to carry out the design in 2D and then in 3D, the first step is to make the sketch of the base, in this case it is dimensioned to have the correct measurements.
Step 2
With the sketch of the 2D image we begin the extrusion and form the cube in 3D
Step 3
On one side of the cube a sketch is generated for the other side to generate the other 2D shape.
Step 4
The extrusion of the shape is generated to the indicated depth, converting the figure into a 3D image.
Step 5
Next, a new sketch is generated and a circle is designed with the dimensions indicated in the 2D image.
Step 6
The design of the circle is extracted by making a 3D image.
Step 7
A new sketch is generated and a circle is designed.
Step 8
In this section, a cut is made with the designed shape.
Step 9
A hexagon is designed for future extrusion.
Step 10
The hexagon is extruded.
Step 11
From all the designs and extrusions, the 3D figure that was required is obtained.
Autodesk Inventor
Autodesk Inventor is a 3D parametric solid modeling package produced by the software company AutoDesk. Users begin by designing parts that can be combined into assemblies. By correcting parts and assemblies, various variants can be obtained. As a parametric modeler, it should not be confused with traditional CAD programs. Inventor is used in engineering design to produce and refine new products, while programs such as AutoCAD are only dimension driven.
Step 1
The following graphic is where the inventor program starts to create 2D and 3D objects, whether metals or other materials.
Step 2
In step 2 you must work in the coordinate space that is chosen in the desired quadrant. To do this, click on the start sketch button.
Step 3
In the chosen 2D plane, we work by giving the dimensions of the object with the distances of the x,y coordinates of the point of origin of the coordinates and of the chosen points.
Step 4
In step 4, the 2D image is extruded into a 3D image, which represents the volume of the extruded image with the desired height dimensions.
Step 5
The following figure shows the image of the object in 3D rotated and cropped in a quadrant shape, where a chamfer can be made with the desired angle.
Step 6
The graphic shows the rotated 3D image of the object, where a through hole has been made, using the previous design of a circle and with the dimensions of the radius and the depth, the perforated object is visualized.
Step 7
The following graphic shows the image of the object in 2D with one of the faces in front view and the other with a view of the back face of the object where the hole stands out on both faces of the object shown.
Step 8
The following figure shows the image of the object in the 2D plane where the front face shows the circular hole. In this way, the Inventor software is used, which quickly supports 2D and 3D designs and also simulates the movement of objects.
Inkscape
Inkscape is a free and open source vector graphics editor. Inkscape can create and edit diagrams, lines, graphs, logos, and complex illustrations. Inkscape aims to provide users with a free, open source scalable vector graphics (SVG) graphics tool that is fully compliant with XML, SVG and CSS2 standards.
How to convert my design to Gcode?
In this space we are going to prepare our files designed with our favorite graphic design program and finally going through the program that converts them to Gcode with the interface that dominates our CNC machine.
Import image
From the file menu go to document properties to select the measurements in mm, then import the image in jpg.
Vectorize bits map
Once the image is selected, we go to the path menu to vectorize bitmap and accept to have a preview of the image where it can be thresholded.
Edit parameters
To edit the parameters, select the image in the Gcodetools menu and in the orientation point in the x,y coordinates put the points (0.0) and put the referred parameters.
Vectorization and image path
The following image corresponds to the coordinates and editing of the parameters of the vectorized image and then moving to the file and directory.
G code generation
We go to file and go to document properties and configure the work page with the following parameters. We change the diameter to 1, which is equivalent to the tip of a pencil. We select all the letters again and go to gcodetools and select path to gcode.1
Conclusions
Computer-aided design (CAD) is a way to digitally create 2D drawings and 3D models of real-world products before they are manufactured. With 3D CAD, you can easily share, review, simulate and modify designs, opening the doors to innovative and differentiated products that reach the market quickly.
