and you are going to create SolidWorks Tutorials for Beginners . Spring is one of the most useful part in every products or mechanical devices. Spring used in every industry in their various forms like open spring, closed spring, conical spring etc. For example, open spring is used in automotive suspension units and also used as vibration dampening devices. They have lot of application and because of that you should know how to model spring in SolidWorks CAD software. SolidWorks spring CAD model

Before going to
SolidWorks tutorial, you should see the various important applications of Spring parts.
They are :-
Compression Spring:- Engines, Power tools, Medical instruments, Pen, Gun etc
Extension Spring: Vehicles, doors, toys, machinery, etc
Torsion spring: Clothspins, clocks, doors, watch etc
Here, you can see step by step SolidWorks Spring modelling tutorial with pictures and videos.
Step-1: New Part File
Open the SolidWorks and
New part File. If you don’t know it, read how to create new part File. Select the Plane (e.g. Top Plane) and normalize using the “ ” Button. Normal To
Step-2: Draw Helix Curve
Features Commandmanager, click on “ Curves” and select “ ” feature tool from the drop down helix or Spiral menu.
It will direct you to
Sketch interface where you have to draw a circle using “ ”. Circle Sketch Tool
If you have particular dimension for your spring, apply the diameter for the circle using
SmartDimesion Tool. Here I am not applying dimension.
Click on “
Then you direct to Features interface where you can see the preview of helix curve. You have to set parameters on helix or spiral property manager.
You can see the above image for parameter values. (R
emember:- it is just a rough sketch for purpose of tutorial only).
Then click on the
green tick button for applying the helix feature. You have created helix curve sketch for Solidworks Spring model. Step 3:- Draw Spring cross section (circle) on End of Helix
Here you are making circular cross section spring model. So, you have to create circle sketch in one end of helix curve.
For that, you have to
create reference plane perpendicular to curve at one end. This is very important step in making Solidworks spring cad model.
Let us see how it’s done.
Click on the one end of helix curve (say
Point 1). Then, go to Features Commandmanager, click on “ ” and select “ Reference Plane Plane”.
Select the “
point 1” as the First reference plane.
The select “
helix/spiral 1” as second reference.
Then your plane will become perpendicular to curve and parallel and contact with point. Here you can make the spring cross section. Go to
Sketch toolbar and select “ Circle” tool and draw it.
Step 4:- Apply Sweep Boss Feature for Creating Spring
Next step is to provide material or body to helix curve. Here you are going to use “
”. Sweep boss or base feature tool
Go to features commandmanager, click on “
Sweep Boss or base”.
Sketch 3” as cross section for sweep boss.
Select sweep path as “
You can see the preview of Solidworks spring cad model. Below shows the final spring cad model.
