You will create this headphone cap during the tutorial :
In this tutorial I assume that you know the basic of solidworks and you should know how to interactively work with the software . this means that you should know how to open a sketch , define a plane and … . if you don’t know the basics you can visit the solidworks beginner tutorials page.
If you had any questions don’t hesitate and ask me. I always will be there for you . this tutorial is free and if you purchased it from some other source you are robbed .now go ahead and start designing with me my friend .
What we use to accomplish this model :
Creating this model is very funny so do it with enthusiasm . before we strat . take another at the model and think about it . if you want to be a good designer you should understand the models . everybody can see the curves and surfaces but a designer should see the relations too . as a designer you should answer these questions to yourself:
What is the most important feature of this product?
Where dose it interact with other parts or products?!
What is the material?!
What is the manufacturing process?!
And all of these questions leads to a primary question:
From where should I start?!
Ok…can you answer these questions about the model?!
I’ll tell you . these are the most important factors to select a starting point:
- Consider simplicity of design
- Consider the future changes of the model
- Consider the symmetry of the model
- Consider the relations between various sections of the model
By considering all of these factors I have selected a starting point which you’ll see . you can do it in different ways and see what will happen . ok…let’s get to it .
Open a sketch on front plane and draw a circle like this:
Extrude it by” extruded surface” on surface toolbar :
We use “lofted surface for the next section and for that we need a new plane and a new sketch so define our new plane:
Draw the sketch on plane1 :
We use “lofted surface” to connect the new sketch :
If your result is different , just manipulate the green connector points to get the desired shape . what is the next step ?! take another look at the model ,we need another loft so define a new plane :
Draw this sketch on plane2 :
Make another loft to create the new surface :
Lets take a look at what we’ve done by now :
The final model is emerging more on every step ,so do you know how we should take the next step?! Think about before I say . yes the answer is another loft so sketch this circle on plane1 :
If you loft the sketch to the edge of the last surface that we created it would be a straight lofted surface , but we want some curvature on the surface this time so we need guide curves on this one . draw these guide curves on right plane in two separated sketches .
Use spline for the guide curves . I didn’t need to fully define them but you can do that if you like . just define each point precisely and then spline would be fully defined . Make the loft just be careful , this time we have some more settings :
Now just the outer edge is left to do . lets give the loft up for a while and do an extrude for the next step . we need a new sketch to extrude but this time we don’t draw anything , just open a new sketch on plane1 and make the following circle by “convert entities” .
Now extrude it .this time we have drafting angle option on :
Lets do something new and use the “revolved surface” for the next step . like any other feature we need a sketch for revolved surface so draw the sketch on the outer edge of the model on the right plane :
And revolve it :
Ok…the end is near . just another loft left to do so define a new plane for our new sketch :
Now sketch the circle on the new plane:
We are going to make our last loft . do it just like the following picture and you’re done .
Congratulation…you have done it .
