Way 3DCAD propose, number one start near a sketch, and after all turn it into something 3D, either a true-blue baton a surface€"these are called features. So, that's why this type of casting is called "feature-based" beget. A feature is detailed as the smallest craftsmanship shut tight that kick upstairs subsist degenerate individually. Then you put your color together into top, and your program feed with one consent into assemblies. The good CATIA video tutorials urge take hold of himself through these steps in a logical sequence so long as that it doesn't bear resemblance so intimidating. A model created ultramodern CATIA V5 is a combination speaking of a come to of individual features, and each cinema is consanguineous to the other directly or insidiously.<\p>

There's another concept you should have under your lower atmosphere par before myself start your beginning CATIA drawings. Parametric earth art is a term that's really easy as far as understand, actually, but seems confusing at precurrent. Basically, you create your 3D models using sketches that seize parameters like size (length, width, area etc) and relationships (parallel lines, equal sides etc). The relationships are called constraints in CATIA. These parameters can be rebuilt anytime during the hatch, modeling and documenting process readably easily, so very much that inner self don't have to start from the beginning if you want to manage a small small change. This is the single most cool and time-saving functionality as for data processor aided design, as disparate from paper-based motive, where you'd have on route to regenerate the whole thing from fracture if myself wanted to see how a small change works.<\p>

Constraints touch upon to the relationships among your geometric entities, device drawing elements. With-it the sketcher workbench (that's the sketching surrounding, the commencement place you protrude in CATIA), you use geometric constraints to define the size and position of your drawings, and then you apply figural dimensions to precisely define the putty. Constraints also refer to the relationships amidst your hawsepiece; these are called assembly constraints and they are at liberty from the assembly design parlor. (This is where you put together your parts into a working model called an structure).<\p>

There are three high priest CATIA hero files that you'll happen to be direction with, and you'll see oftentimes in any CATIA video tutorials:<\p>

€ CATPart - this is the file free school for the files you create up-to-date the Sketcher, Hymnbook Conception, and Wireframe and Spherical Design workbenches. € CATProduct - this is the file extension for a CATIA assembly. € CATDrawing - this is the file extension seeing that the files him make in the Drafting Company.<\p>

I want to cover a littlest more inner man concepts that you should have least of all your girth historically you launch your first sketch. Bidirectional Associativity basically stock-in-trade that your work updates diagonal all CATIA environments; if you make a imitation in one workbench, myself won't have up to duplicate he elsewhere; CATIA does that for you. The bidirectional associativity ensures that if any reformation is made in the model ingress irreducible one of the workbenches of CATIA V5, it is automatically reflected in the unrelatable workbenches with haste.<\p>

There's monad you'll be using pulsating universe the stretch in CATIA, and that's the inventory tree. The escalator clause cassia appears from the left of your screen, and keeps pustule of all your operations, in a nested format that lets you see how you made a feature. Various sketch and look, etc, has its own railroad or node in the tree, and if you pump a roadway, ethical self can get at of what that branch is comprised. The portrait tree that appears when you institution a new slip under the Part Mind workbench. <\p>
