CATIA sketcher workbench is equipped with SKETCH TOOLS that generates free sketches. With the help of Geometric & Dimensional Constraints, Construction elements/standard sketches are optimized and fixed. These sketches are then used to convert 2D drawings into 3D models. Sketcher can generate reference sketching that assists the drawing.
CATIA uses different extension for different modules, listed as:
- CATPart: Sketcher rooms
- CATProduct: Assembly
- CATDrawing: Part design
CATIA allows customizing various toolbars by simply dragging and dropping, but you cannot drag and drop local commands onto global toolbars. Select Tools<="" div="" style="box-sizing: border-box;">

Dimensions are numerical values assigned to sketch entities. Desired dimensions after the machining are called as true dimensions. There are permissible limits assigned to dimensions called as tolerances. CATIA has provision to assign tolerances to dimensions. GD&T uses symbols to represent characteristics of an entity. E.g. – for horizontal, | for vertical, = for equal length etc.
Spline creates continuous tangential curvature passing through number of points. On the other hand spine is curve passing through say pt. b on a particular plane and normal to other plane. Both words are inspired from Spanish community in human body carrying pulses through spinal chord.
NURBS is abbreviated for Non Uniform Rational B - Spline curve. NURBS mapsonevariableis say "p" from the parametric into 3D X (p)/W (p), Y (p)/W (p), Z (p)/W (p) where every component is a rational B - Spline. Rational B- spline curve represented by order of a curve and no. of segments. There is various control points that represents and manipulate the spline. Software also provides general blending functions that govern the spline.
Sketcher constraints apply positioning relevance to the entities with certain reference.
Constraining the sketch makes it fixed and doesn’t get affected in using it in other workbench, other software or after reopening it in same domain. In CATIA using geometric constraints sketcher entities can be constrained. Constrained sketch turns green from white in CATIA sketcher.
A co-ordinate system is a reference system that contains 1 origin point and 3 axes X, Y&Z. To create your own system go to Insert> Axis system. Once the Axis system definition dialogue box pops up, you can select a new vertex to define new origin and provide 1 axis. Remaining axes will be computed and shown accordingly. For initial sketch, you need to select one of the plane formed by these 3 axes to enter in the sketching workbench.
Sometimes for critical models it is difficult to create a model in single design. At such times multibody function is used. Multibodyreferes to generating more than 1 model of final component at different planes and then using Boolean operations, final model is obtained. CATIA provides multibody platform in the form of Booleans, part design, surfacing and parametric design.
Solid combine is very useful tool in CATIA that calculates the intersection in virtually extruded profiles. When you click on solid combine it will ask you to select first and second component. In components you can select sketches, surfaces or 3D planer curves.
Product can be saved as a separate document and it can be used in other assembly. Product is a completed version itself; on the other hand component is part of product.
PLM means Product lifecycle management. PLM can collect the date, process it, relates it with various business systems and humans. PLM works throughout from the production of a component to its extinction based on life estimated while designing. PLM soft wares make it easy to relate the design, manufacture, service and disposal of a product.
Yes, we can.
For example, we can create a cylinder in 5 ways.
Profile toolbar consist the geometry creation tools whereas sketch tools toolbar allow you to work in different modes which make sketching easier.
The sketches which are fully defined with respect to dimensional and geometrical constraints are shown as ISO Constraint.
Line can be converted into axis but axis cannot be converted into line.
The pocket which consists of a draft on all faces and fillet on all lateral edges is known as drafted filleted pocket.
This error occurs when the sketch is inappropriate to be converted into 3D.
Both guide curves and centre line are used for reference.
Guide curves controls the intermediate profiles that are needs to guide along particular path.
Centreline controls the shape of the part centrally using a path.
Each component has 6 degrees of freedom before assembled. Then particular degrees of freedoms get restricted due to constraints applied in assembly. Initial component is fixed in assembly, with 0 degrees of freedom
A surface model is a very thin layered product. In software while modelling, surfaces considered as zero thickness components. Ideally such parts do not exists. In modelling thickness separates surface from sheet metals. Surface structures are generated using wireframe model to manipulate the shape of a component.
Yes, it is possible to shell the sphere.
Class A surfaces are textured, highly surface finished, visible surfaces that have most significance in assembly. Class a surfaces generallydoesn’t have Rib, boss or snap etc. On the other hand, Class B surfaces are invisible in assembly and have boss or rib if needed. Class b surfaces have tangent continuity.
A sheet metal is thin and flat piece of a metal. Although sheets have thickness it cannot be exceed more than 5mm, else it calls as solid part. A sheet metal undergoes drawing, bending, forming, cutting etc to transform into finished good.
