Catia is a computer-aided design (CAD) and computer-aided engineering (CAE) computer program. You can divide its function into two parts - it has a 3D modeling interface with tools and commands like Extrude and revolve. Both surfaces and solid modeling functions enable you to computer aid any design and make vast assemblies, with absolute certainty that everything fits together and that you have a sustainable design regarding 3D modelling.

Catia is the only solution capable of addressing the complete product development process, from product concept specification through product-in-service.

Catia is a true collaborative engineering software, including style and form design, mechanical design, equipment and systems engineering, managing digital mock-ups, machining, analysis, and simulation.

With Catia we can create 3D models using parametric or direct modeling features. We are also able to use some advanced surfacing features to add curves and reform your 3D model to your specifications. Parameters refer to constraints whose values determine the shape or geometry of the model or assembly. It has all the standard parameters that can be used for creation of line lengths or circle diameters, or geometrical elements such as tangents, parallels, concentrics, horizontals or verticals, etc. Catia can also achieve  easier and more accurate design, which allowing it to capture design intent.

Catia also has features such as the option for analyzing a model. Once we have started our model, we can do some simulations. With Catia's 2D system analysis tool, we can be sure that our 2D designs are error-free.

Catia enables the creation of 3D parts, sketches, sheet metal, composites, molded, forged or tooling parts and combining them in assembly mode, giving relations for every part following original artistic design if needed. The software has tools for mechanical surfacing. We can complete product definition, tolerances, as well as kinematics definition, which separates Catia from other software. We also can facilitate the design and manufacturing of electrical systems, whole process to production. Electrical schematic definition and interactive 3D routing of both wire harnesses and industrial cable solutions are now easier to do than before.

The geometric elements in Catia can be defined in two ways; one way is an exact definition of elements with respect to certain number of constraints, and the other way is to have an approximate definition using solids.

In wireframe models we have wireframe design using points, lines and various curves. With surface modeling we are extending wireframe geometry by giving it some sort of support (faces). We then have solid models and they can be defined by using a faceted volume or directly define it.

With Catia we can also do tubing, piping, heating, ventilating & air conditioning (HVAC). We can create 2D diagrams for defining hydraulic, pneumatic and HVAC systems, as well as piping and instrumentation diagram.

Catia consists of modules:

1. Sketcher


2. Part design


3. Assembly design


4. Drafting


5. Generative Shape Design

If you need assistance with Catia courses or just drawings in general, we provide Catia tutoring both online and through homework help with qualified tutors that cover other Engineering programs as well. Our tutors are made up of teachers at the college level, graduate students, and professionals in the engineering field. 

Our tutoring and homework help model is built to help you whenever you need it. To use our homework help service, all you need to do is fill out our submit form letting us know your due date and upload any supporting documents and materials. Our tutors will respond to your request, sometimes in minutes! They will give you a quote based on how long it will take to complete the assignment. Once you receive your quote you are free to discuss the quote and any concerns with your tutor. There is no obligation with our service. We want you to feel comfortable with the tutor of your choosing.

You have the option to choose a specific tutor from our selection of Catia tutors or you can submit your tutoring request so that all Catia tutors can see it.

Our tutors are available 24/7 in our Tutor Center.  Each tutor can assist you in both live tutoring sessions and homework at any academic level, from bachelor's degrees to doctorates. 

If you have a specific Catia assignment with which you are having trouble, we also have Catia homework that has been completed. You can use past assignments as guidance for completing your current Catia homework. Our homework library is a vast collection of completed homework assignments so you can find the right content to fit your needs.

To fulfill our tutoring mission of online education, our college homework help and online tutoring centers are standing by 24/7, ready to assist college students who need homework help with all aspects of Catia. Our engineering tutors can help with all your projects, large or small, and we challenge you to find better Catia tutoring anywhere.
