3. Computer Aided design¶

Modeling on 2D¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

Inkscape: Software that allows you to vectorize graphics and improve their quality, can be used by professional and amateur designers. I did not know the software is new to me, it is very easy to work with and educational.

Inkscape

Support me with a video on YouTube:

Inkscape it helped me a lot to use some commands.
Select a referential Image: Logo of the study program of Industrial Electronics of the IES “SB”.

Use the tool to draw Bézier curves and straight lines.

To copy: First select the image then right click select copy

Apply vertical symmetry: Go to objects file then go horizontal reflection

Group:: First step: Select and transform objects

Then right mouse click select group

Using CorelDRAW 2019

Select and click on new document – Complete data

then click ok

Now to start designing:

Click file browse import - click, then browse image to import

Use artistic media tool, border the hand without considering the fingers

Freehand tool, to make the edges of the fingers of the hand

To reduce or enlarge the design you must rotate the middle mouse button

To save the changes click on the figure of a diskette or Ctrl + S, then specify the location or path to save the design

To improve the contour click on the nodes

Then just to select

To rotate the image click and specify the angle of rotation

To select all the images you must left click and drag until you select everything you want, then click and specify the angle of rotation.

In my opinion, designing in 2D with Inkscape made it easier for me to work with respect to CorelDraw. In addition, I have to add that working with unlicensed programs allows us to contribute to their improvements, in the case of Inkscape.

Modeling on 3D¶

Working Fusion360 – Probable Final Project

Fusion360 is software from the Autodesk CAD, CAM family, it allows printed circuits to be made with 3D modeling based on the cloud for the design and manufacture of products, widely used by professionals and amateurs, it is very easy to use, its modeling begins with the 2D sketch creation to then build 3D solids. It is very interesting.

Fusion360: Software that allows you to vectorize graphics and improve their quality, can be used by professional and amateur designers. I did not know the software is new to me, it is very easy to work with and educational.

Fusion360 You can download the free trial version, more information in the link.

Fusion 360

Entering Autodesk Fusion360 Configure the units

Now select the plane to work

On the sketch, create a rectangle with the following tool

With the extrude command a cube was generated

With the Fillet command, the edges of the body of the solid were rounded.

To configure the splice, select the edges and enter the required dimension

The visualization of the changes applied by the splice

NEW PLAN CREATE SKETCH: Select the body where the new body will be created

Click on create a sketch

THEN PROJECT Click create, the select project brings up a dialog box

On the sketch, create a rectangle with the following tool

CLICK PROJECT

Result of projecting

I generate two rectangles

Finish Sketch

Use the exclude command to

Then select the excluded área

Specify the distance to exclude

The result of excluding

Apply the dump command

Select shell area, specify interior thickness

To create the lid Create new sketch

Go to create, select project

Click exclude

Specify the dimensions later, in this case, as a lid is being prepared, the operation to select is a new body

Then click accept

Create body components1

Create body components2

Click on union

for body movement Click on assemble union

Component Motion Effects

Progress of the final project

Design in SOLIDWORKS

Design to build1

Click on new document, select part and accept

Click on the sketch file then select sketch

Then select elevation (First quadrant)

Then verify the measurement unit system to be used in our case MMGS, it is in the lower right part of the screen.

Select construction line

select sketch

Then click smart dimension

Then select the side view

then hide the plane

Then select rectangle, from the point of origin

Select Isometric View

Then clip entities

Until fully defined

Select the sides and place the same

Then generate the new view

Then place the angles of 45° and the distances of 16

overall height 75

Extrude forward 15mm

Then select reference geometry, select plane

In the middle plane build

In the middle plane build

Extrude 12mm from the midpoint

Then change Appearance – Color

Modeling on 3D - Parameters¶

EMG SENSOR BOX

Steps to follow to work in Fusion 360: Go to modify then select change parameters

Then click on the + to use parameters, then Add names

Then accept, if you want you can also add more parameters… Then create a cylinder

Then click on the view and then accept

Then click the center to input cylinder data, then put the parameter data

Then use the shell tool, place parameters

Then create a new sketch on that face

then project

Then hide the body, then apply the offset tool, then place the tolerance data of the parameters

Then finish sketch or sketch

Then extrude, placing data from the thickness parameter

I can hide body 1, activate body 2 and activate sketch

Extrude sketch 2, in distance place the thickness parameter.

You have to add parameters

Apply a circular pattern tool

Add a parameter

Then round is the fillet tool

Then the rounding /2 in the feed box

Then right click with the mouse to displace one body from another, to generate the impression

Modeling on 3D - Renderizado¶

To render

Designing in 3D with Fusion 360 was interesting since I had not had the opportunity to work with this type of program, it seemed friendly to me because it is from the Autodesk family because I already knew something about AutoCAD but in 2D it brought me very close to this software with respect to the SolidWorks since it is very interesting and it seems more complete but I need to explore more about it, in my case I am working with Fusion 360 with an educational license and, in the case of SolidWorks my free license expires in 7 days so I have very little time left to explore for now.
