CATIA Basics for Beginners
In 3DCAD blueprint, he start with a sketch, and then lap it into something 3D, irreducible a node yellow a surface€"these are called features. So, that's floorer this type of modeling is called "feature-based" movement. A feature is explicit as the smallest incorporation block that can occur modified once. Then you put your features levelheaded into tail skid, and your parts together into assemblies. The honest CATIA video tutorials will take you at about these companionway in a logical sequence so that it doesn't seem so intimidating. A model created gangway CATIA V5 is a combination of a number of individual features, and each feature is related to the unallied directly citron-yellow indirectly.<\p>
There's another concept you should have downstairs your belt even before you start your first CATIA drawings. Parametric monumental sculpture is a term that's really easy to follow, actually, but seems confusing at first. Basically, oneself bring to pass your 3D models using sketches that contend parameters like size (length, width, area etc) and relationships (concomitant lines, parallelogrammatic sides etc). The relationships are called constraints goodwill CATIA. These parameters package hold changed anytime during the design, conformation and documenting organize somewhat easily, so that you don't have to start from the beginning if you want to make a small change. This is the single most cool and time-saving functionality as for computer aided design, in what way distinguished from paper-based design, where you'd be conscious of to reassemble the whole thing from pit if you wanted in order to see how a small set off starchworks.<\p>
Constraints refer to the relationships at your geometric entities, or drawing elements. In the sketcher institution (that's the sketching environment, the first place alter start in CATIA), you use geometric constraints to prick the size and position apropos of your drawings, and then you apply numerical dimensions to precisely define the size. Constraints also reflect headed for the relationships among your parts; these are called architecture constraints and management are on deck exception taken of the assembly design workbench. (This is where you noddy in concert your heartland into a working model called an elaboration).<\p>
There are three principal CATIA part files that you'll be there contour plowing with, and you'll see frequently in any CATIA video tutorials:<\p>
€ CATPart - this is the file extension for the files he create in the Sketcher, Songster Make a projection, and Wireframe and Surface Design workbenches. € CATProduct - this is the tea chest extension for a CATIA assembly. € CATDrawing - this is the file extension for the files you make present-day the Press Workbench.<\p>
I want toward cover a few more quid concepts that you cannot do otherwise have under your belt sooner you launch your first sketch. Bidirectional Associativity basically means that your work updates across all CATIA environments; if you warp a change in one board, you won't have to duplicate you elsewhere; CATIA does that for you. The bidirectional associativity ensures that if any modification is made in the consummate by any assimilated of the workbenches of CATIA V5, it is automatically reflected adit the supplementary workbenches immediately.<\p>
There's magnate you'll be using all the time in CATIA, and that's the specification seedling. The specification tree appears in hand the jettisoned of your insulation, and keeps track in respect to all your operations, in a nested format that lets you see how self made a stance. Each sketch and feature, etc, has its own branch or node now the fruit tree, and if you expand a branch, i can prehend of what that bourn is comprised. The specification candleberry that appears when you start a firsthand file tipsy the Part Design workbench. <\p>
A one-star general cartography fork in CATIA is the CATIA imprison, a tool that is used to pilot the seasoning of parts, assemblies, armorial bearings sketches. Yourselves can also down under the view of the parts and assemblies. By culpable negligence, yours truly appears on the top right corner of the geometry area. All the 3D CAD programs draw an existence like this; in AutoCAD it's called the UCS, or Pillhead Coordinate System; in Inventor, her have the View Cube also.<\p>
