Cad Research Paper

It was implemented in a Computer-Aided Design (CAD) course on the Bachelor’s Degree in Industrial Design and Product Development Engineering.Several studies have been published about CAD curricula, yet to the best of our knowledge nothing on applying Action Research (AR) to CAD teaching.From the point of view that today’s student is tomorrow’s engineer, descriptions have also been put forward regarding what CAD curricula should be like depending on the role CAD will play in the student’s future (as a user, an application developer, a software developer or a CAD manager) (Ye, Peng, Chen, & Cai, 2004).

With Instant CAD, the process of improving and optimizing the design can be done in real-time, saving engineers days or weeks.

After an object is designed in a commercial CAD program, it is sent to a cloud platform where multiple geometric evaluations and simulations are run at the same time.

In that study, the authors presented the results of a survey about different issues carried out on over 600 teachers.

It revealed that, in Spanish universities, there was no agreement on the desirable number of students in the labs, the time to be dedicated to practical sessions, the CAD software to be used or its type (parametric or not) or on the system of evaluation.

The main actions were to develop self-learning material and to use rubrics for assessment, together with an increase in the level of difficulty in some parts of the evaluation.

A detailed chronological description of the actions that were carried out, the implied motivations and both the expected results and those actually obtained are presented.“It’s too data-intensive to compute every single point, so we have to come up with a way to predict any point in this space from just a small number of sampled data points,” says Schulz.“This is called ‘interpolation,’ and our key technical contribution is a new algorithm we developed to take these samples and estimate points in the space.” Matusik says Instant CAD could be particularly helpful for more intricate designs for objects like cars, planes, and robots, particularly for industries like car manufacturing that care a lot about squeezing every little bit of performance out of a product.Down the line, she hopes that Instant CAD can also help lower the barrier for entry for casual users."In a world where 3-D printing and industrial robotics are making manufacturing more accessible, we need systems that make the actual design process more accessible, too,” Schulz says.However, it can be difficult to determine the absolute best design for what you want your object to do, because there are many different options for modifying the design.On top of that, the process is time-consuming because changing a single property means having to wait to regenerate the new design, run a simulation, see the result, and then figure out what to do next.The project was carried out over a two-year period, after detecting that academic results were not very good even when the course was not very demanding.In the first year, an experiment based on the AR methodology was planned and put into practice.Traditional CAD systems are “parametric,” which means that when engineers design models, they can change properties like shape and size (“parameters”) based on different priorities.For example, when designing a wind turbine you might have to make trade-offs between how much airflow you can get versus how much energy it will generate.
