1. Project Management

Research

In this week focused on 2D and 3D modeling, the basics of new modeling were learned.

Installed Software

This week, the following software will be used. You can download the programs using the following links or by searching for the program names in your browser:

Software Function
SolidWorks 3D CAD software for mechanical design and engineering
Fusion 360 Cloud-based 3D modeling, CAD, CAM, and CAE software
Blender Open-source 3D creation suite for modeling, animation, and rendering
Inkscape Free and open-source vector graphics editor

Inkscape

Is an open source vector graphics editor, similar in capabilities to programs such as Adobe Illustrator, CorelDraw and Xara X. In this case the idea of a drum practice pad was developed.

As Inkscape practice, a hexagonal-shaped drum practice pad will be designed as a preliminary design. This project uses basic software tools and functionalities, providing an opportunity to learn vector design skills. After completing the first practice, a proposal will be made on the layout of the drum kit for a practical use design.

Using the Polygon Tool

And in the upper section, indicate that it is a polygon and set the number of vertices to 6 to create the figure. Then go to the Fill and Stroke menu. Select the fill color, which in this case is gray.

Then select the border color, in this case brown, using the stroke color menu.

With this, we would obtain the lower image of a drum practice pad.

Using the previously mentioned tools, a sketch of a possible distribution of the electronic drums with three cymbals and 4 drums was made.

The base was created with the ellipse tool; using control we can draw perfect circles.

Example

Fig 5. Creating the base with the ellipse tool

To create the interior of the drum cymbals, use arcs with the ellipse tool. In the top toolbar, look for the "Start" and "End" options. Set the "Start" value to 0 and the "End" value to -180 to create the arc. Then, in the "Fill and Stroke" menu, remove the fill to have only the outline.

Example

Then the circle was duplicated and aligned so that it is concentric with the align and distribute menu by centering the horizontal and vertical axis.

Example

The image below shows the result.

SolidWorks

For the 3D modeling, various software were used. A prototype of a cymbal was created in SolidWorks, from designing, placing materials, and rendering.

First, the curvature tools were learned using circles as a base, as well as the extrusion tools. .

Cymbal1

Use of different inclination angles were tested to observe their differences. A cut was made on the lower side of the piece to simulate a real cymbal

To create the lower space, a smaller concentric circle was drawn, and then the cut-extrude tool was used to generate this space, simulating a cymbal. Next, the cut-extrude tool was used again to create a cylindrical space in the cymbal.

Finally, using the pattern tool with the configuration shown in the image, the previously mentioned cut and extrusion action was repeated multiple times

The split line tool was used to divide the circle into two spaces, aiming for an aesthetic design, and the circular pattern tool was incorporated to make the holes symmetrically.

Materials were applied during rendering to make our 3D model look more realistic.

Blender: Create a drumsticks

Different tests were conducted on how to use the software and its basic tools. For example, to make the top part of the drumstick, a cylinder with 7 vertices was used, which, when using the S scale tool, allowed us to generate that shape. Various tests were carried out to generate the drumstick. Among the commands used were Tab to enter Edit Mode and S combined with X or Y to adjust according to the coordinates.

Drumstick

  • G - Move
  • R - Rotate
  • S - Scale
  • E - Extrude
  • Tab - Toggle between Object Mode and Edit Mode
  • Ctrl+B - Bevel
  • Shift+D - Duplicate
  • X - Delete

For the lower part of the ramrod, the extrusion tool (E) was used to lengthen the cylinder and give it the desired length, this action was complicated to perform with the mouse because it is difficult to do it with precision

Fusion 360

In addition, the saucer was also created in Fusion to interact with both programs. The creation process is very similar, starting with the creation of a circle and using the extrude tool. Although there are slight differences in the interface and the way instructions are given to the software, the same operations of extruding, cutting and modifying geometries are performed. These actions allow the design to be adjusted to the required specifications,ensuring that the end result is the same as in SolidWorks.

Animation Video

To create an animation in Fusion, first switch to the animation workspace from the menu at the top left. Then, set up the camera view and record the view. Finally, before starting to record, adjust the timeline.

Conclusion

Creating this 3D design involved learning different basic tools, such as extrusion and cutting, as well as learning basic concepts like using concentric circles or decorative details.
