EXERCISE- 10: HOW TO DRAW A PERFECT STAR?

       Go to respectively; Start> Shape> Generative Shape Design.




Click “Point” and set coordinates as X= 0, Y= 50, Z= 0. Press “OK”.




 Click “Point” one more time and set coordinates X=0, Y=-25, Z=0. Press “OK”.




 Select “Line Definition” for selected point and select “Create Point” on coordinates (0, 0, 0). Select line type as “Point- Direction” and pick direction as Z component. Set start distance as 12 mm.





  Select (0, 50, 0) coordinated point and go to “Circular Pattern Definition”, set parameters
“Complete Crown”; instances will be “5” and “Z Axis” will be the reference element.





   Select (0, -25, 0) coordinated point and go to “Circular Pattern Definiton”, set parameters as “Instances and angular spacing”, instances: 5, angular spacing: 72 deg and reference element will be “Z Axis”, press “OK”.



Go to “Line Definition” and select parameters respectively as shown below.




Go to “Fill Surface Definition” and select three created lines, press “OK”.



Now, select “Symmetry Definition” as follows and press “OK”.



Select “Join” and pick two pieces to make them one part.




Go to “Circular Pattern Definition”, select the part that recently joined eachother and set reference element on Z Axis.



On join definition part select all the first created part and the rest which has created by using circular pattern definition to join eachother.



Select “Symmetry Definition” to create the pther half of the star. After that click to “Join” to stick two half stars.



The “Perfect Star” is completed. Well done!

CATIA- Toolbars - Chapter 2

3. 3D Modelling Toolbars:



3.1. Sketch- Based Features Toolbar:



 Rib  This icon helps you to sweep your closed profile along a center curve
 Slot This tool is opposite of "Rib" command which is allow you to remove material on 3D model along a centr curve
 Multi Section Solid It allows you to create solid along the selected two or more closed intersecting curves
 Removed Multi Section Solid  It remove the volume which is defined in two or more closed intersecting curve along the extrusion


3.1.1. Prisms Sub-Toolbar:


 Pad It allows you to create a prysmatic shape on defined directions
 Pocket This icon allows you to extrude the shape. It can be partly explained opposite of "Pad"
 Drafted Fillet Pad It allows you to create prysmatic shapes with requested angle and length. It also helps to round the edges on sketch
 Drafted Fillet Pocket This tool allows you to create a pocket with draft and fillets
 Multi-Pad This tool shows you how to multiple th edefined sketch with different lengths
 Multi- Pocket It helps you to create multi pocket at the same sketch environment

3.1.2. Revolving Sub- Toolbar:


 
 Shaft It allows you to revolve your 2D profile on defined axis, in this way you can get a 3D model
 GrooveThis tool allows you to create a new solid model by removing the material on revolved profile with defined dimensions and angles 

3.1.3. Advanced Extruded Features:


 Stiffener It allows you to create a support piece to increase mechanical strength
 Solid Combine It creates solid model by selected two perpendicular and defined direction which is on intersecting height 



3.2. Transformation Features Toolbar:


3.2.1. Transformations:








 Translation It allows you to make the solid model on defined distance, type or axis
 Rotation It allows you to rotate the solid profile on selected axis and angle
 Symmetry     This tool allows you to take symmetry according to defined reference such as; solid model surface, plane objects...etc
 Axis to Axis It allows you to translate the body by using the reference axis to target axis

3.2.2. Patterns Sub- Toolbar:








 Rectangular Pattern It allows you to duplicate rectangular objects
 Circular Pattern It rotates the selected oject according to reference axis
 User Pattern  It allows you to duplicate defined objects many times according to specified points

3.2.3. Scale Sub- Toolbar:



 Scalling This tool allows you to scale your objects as requested ratio
 Affinity It allows you to change and translate according to the ratio values of the coordinates

3.3. Dress Up Features Toolbar:








 Chamfer This tool allows you to chamfer on defined edges
 Shell It creates a shell on existing solid shape
 Thickness It gives thickness on defined surfaces
 Thread/ Tap It threads by specifying the type of thin or thick


3.3.2. Fillets Sub- Toolbar:








 Edge Fillet This tool allows you to create constant radius on defined edges of solid model
 Variable Radius Fillet It allows you to create variable radius on defined edges
 Chordal Fillet This tool allows you to create a fillet by specifying width of the fillet ribbon
 Face- Face Fillet It assigns an intended radius between two different surfaces to give a round shape
 Trtitangent Fillet It allows you to create radius which will be tangent three surfaces of solid shape

3.3.3. Remove Sub- Toolbars:



 Remove Face It deletes the other surfaces accroding to reference surface
 Replace Face It regenerates the selected sruface according to reference surface

3.4. Surface- Based Features Toolbar:









 Split   It helps you to cut off solid model by using a plane or a surface
 Thick Surface   It creates solid model by giving thickness in one or two direction on selected surface
 Close Surface It creates a solid model by filling selected hollow surface
 Sew Surface It performs a boolean operation by combining a solid model


3.5. Boolean Operation Toolbar:








 Assemble This tool is allows you to stick two solid model eachother
 Union Trim It allows you to cut off intersecting part of solid models or allows you to create new solid model by holding requested part
 Remove Lump If the model existing in two or more parts, it allows you to remove unwaned objects


3.5.1. Boolean Sub- Toolbar:








 Add  It allows you to add selected solid model to another
 Remove It allows to remove selected solid model from another
 Intersect It allows to take intersection of selected solid model with another
