Introduction of Solid-works

INTRODUCTION 

Solid works developed by dassault system is a CAD software which is widely used for designing in automotive and mechanical industry. It is a feature based, parametric, solid modeling mechanical design and automation software.

Some of the important mode of solid-works:-

   >  PART MODE

It is feature based parametric environment in which you can create solid models

You are provided with three default planes named as front, top and right plane.

First you need to select a plane to create the sketch for the base feature. On selecting a sketch plane, you enter the sketch environment, where sketch models are created. After sketch you can specify their dimension and apply the relation in same sketching environment.

   >  ASSEMBLY MODE

In assembly mode you can assemble/join different parts and make a product with the help of required  tool.

   >  DRAWING MODE

This mode is used for documentation of the part or the assembly created earlier in the for of drawing view and details in the drawing view.

IMPORTANT TERM AND THEIR DEFINITION 

   >  Modeling feature based 

A feature is defined as smallest building block that can be modified individually. In solid-works the solid models are created by integration a number of these building blocks.

                       A model created in solid works is a combination of a number of individual feature that are related to each other directly or indirectly.

   >  Parametric modeling 

The parametric nature of a software is define as its ability to use the standard properties or parameter in defining the shape and size of geometry.

The main function of this property is to derive the selected geometry in new size and shape without considering its original dimension. You can change and modify the shape and size of any feature at any stage of design process.

   >  Bidirectional assosciativity 

As mentioned earlier, solid-works has different modes such as

Part, assembly, drawing, among all these there exist a bidirectional associativity. This feature ensures that any modification mad in the model in any one of these modes is automatically reflected in other modes immediately.

   >  How can we change the units ? 

   -  Go to tools menu
   -  Then go to option
   -  Chose system option then general
   -  Next choose document properties.
   -  Choose unit system
   -  MKS, CGS, MMGS, IPS, CUSTOM
   -  OK

   > GRID/SNAP

   -  Select the grid type
   -  Enter major grid spacing (25-4)
   -  Miner line (4)
   -  Snap point per minor (1)
   -  Ok

How to convert 2D Drawing into 3D Drawing Command

Open 2D Drawing and change the view of drawing to isometric like NE, NW, SE, SW view, And, after this you can specify height to than 2D  drawing.


VIEW PORT
Using this command you can an object in different view as-top, bottom,left, front, back, SE isometric, SW isometric, NE isometric, NW isometric view.

   -  Select command ( view > view port )
   -  Select view-port like 1, 2, 3, 4
   -  Choose horizontal or vertical
   -  Now, change the view in all view-port according to your requirement.

EXTRUDE
Using this command you can specify height to any 2D poly-line drawing. And after this you can convert any 2D drawing into solid object.

   -  Select command extrude
   -  Select poly-line to extrude
   -  Enter
   -  Specify height
   -  Enter

Extrude

BOX
Using this command you directly create 3D box by specifying

   -  Select command
   -  Click on first point from where you have to create box.
   -  Now, press L to specify length of the box.
   -  Then specify width and height of the box

Box

PRESS PULL
Using this command yu can specify height to any closed boundary either of line or poly-line. Also, you can increase or decrease height by selecting the face of 3D solid.

   -  Select command
   -  Click inside the boundary
   -  Specify height.
   -  Enter

Press Pull

UNION
Using this command you can combine two or object and become single body.

   -  Select command union
   -  Select both object
   -  Enter

Union

SUBTRACT
Using this command you can subtract one body from another body either in 2D or 3D

   -  Select command subtract
   -  Select body from which you have to subtract another body.
   -  Enter
   -  Select body that has to subtract
   -  Enter

subtract

INTERSECT
Using this command you can create command part of tow object

   -  Select command intersect
   -  Select both object
   -  Enter

Intersect

RENDER
Using this command you can apply material from material browser, and light.

   -  Select command
   -  Click on material browser
   -  Now, select 3D object to apply material and click on (up) Arrow.

Render

SWEEP
Using this command you can create tube like structure, create thread, 3D strings etc.

   -  Firstly, you can make path that has to create 3D.
   -  Now, create profile of that shape that has to create structure.
   -  Select command
   -  Select path to be followed
   -  Enter
   -  Select profile that has to create 3D structure,

Sweep

REVOLVE
Using this command you can create that type of object which looks like circular from top view and of some profile from front view. Through this you can create pot, hinge, shaft and different type of bolts etc. In this, you make half structure and you can create full structure from this command.

   -  Firstly, make profile according to your requirement
   -  Select command revolve
   -  Select profile that has to revolve
   -  Enter
   -  Specify axis that should parallel to the profile
   -  Specify angle of revolving as 60, 270, 360
   -  Enter

Revolve

LOFT 
Using this command you can create 3D object using two or more profile (Poly-line). Though this you can create tunnel shape, blower etc.

   -  Firstly, make tow or more profiles at some distance in z-axis.
   -  Now, select command loft
   -  Select all profiles for loft
   -  Enter
   -  Enter

Loft
