Computer Design Aided

2D MODELING

Logo Design

To design my logo I used INKSCAPE which is a free and open source vector graphics editor. Install and run Inkscape and I open a new document in inkscape.

Copy the template image to use and paste it into the Inkscape sheet.

I am going to vectorize the model image.

After having vectorized it, I delete the original image and select the vectorized image where you can see the nodes that compose it. I start to erase the nodes to be left with only the flower petals.

I draw an area using the Bezier tool and give it a green fill color and then send it to the background.

I use from the object menu the command lower to the bottom and thus the stem can have a fill color.

To download typography enter the following address:

and then click install.

I also vectorized the text and gave it a fill color and remove the border color.

Finally the image I group it and export it as PNG.

I have used COREL DRAW as a design program and here you can download my worked files. Download here.

Some photos that show the process carried out can be viewed here.

2D Box Design

To model the jewelry box in 2D use Autocad. Create layers to work with the lid, interior, outline, and more. I create layers with LAYER PROPERTIES giving them a name and a color.

We are going to save the file in Autocad 2D.

We start by using the LINE tool, fix a point on the plane and click on ORTHOMODE to then give it a length of 15 cm and press enter twice.

I select the line. I disable ORTHOMODE. I click on the ROTATE tool. I mark the base point that is the beginning of the line and then I indicate the 30 degrees to finally press ENTER.

Activate ORTHOMODE again. I click on the point where the line starts. Click on the LINE tool and draw the second line indicating the length of 11 cm.

I select the vertical line. I disable ORTHOMODE. I click on the COPY command then I click on the reference point that is the end of the horizontal line and we see that it is positioned and we click and then ENTER. I do the same procedure with the horizontal line.

I click on the COPY command and I select each line of the rectangle and I click on the base point and indicate the distance of 20 cms and I click and then I press ENTER.

I join the two rectangles with the LINE tool and bring some lines to the inner layer.

We've copied lines with the COPY tool and given it a 30 degree slant and brought it to the top layer.

We add the layer of divisions and trace with the LINE tool these internal divisions of the jewelry box.

We add the layer called cladding and draw a 0.5 cm circle on one of the intersections with the CIRCLE tool. radio

Now let's set the bounds.

I have used AUTOCAD as a computer aided design program to model in 2D the jewelry box to be made. Here you can download the worked file (diseño_de_cofre.dwg and diseño_de_cofre.bak).

3D MODELING

STEP 1

I open the SOLIDWORKS program and choose part.

STEP 2

I choose plan view to build the base of the object.

STEP 3

I save the file as jeweler-main.

STEP 4

Check units in centimeters

STEP 5

I right click on plant to choose NORMAL A to work on the front side.

STEP 6

I choose the line command in the sketch tab.

STEP 7

Draw a rectangle by clicking inside the indicated area not taking the measurements into account yet.

STEP 8

I click on smart dimension to give them the necessary measurements.

STEP 9

I select the line and move to the left and then release the line and a window appears where I indicate 15 cm as the measurement. Then I click on the green check.

STEP 10

Then I select the upper line and apply the previous procedure and give it the measurement of 20 cms.

STEP 11

To build upwards, I first build the 2 cm area by choosing the extrude boss/base command from the operations tab.

Here we have the lid of the jewelry box in acrylic material

Finally we have the piece that goes inside the jewelry box

I have used SOLIDWORKS as a computer-aided design program to model the jewelry box to be made in 3D. Here you can download the worked file (joyero_PIEZA.SLDPRT , joyero_principal.SLDPRT and
joyero_TAPA.SLDPRT).

Animation

To perform 3D animation in Solidwors, an exploded view of the designed object is created; then enter the Motion Study tab and use the animation assistant to indicate the corresponding animation. The following series of animations was chosen: rotate – explode – collapse – rotate, as shown in the following video:
