SolidWorks 2015

Few weeks back, SolidWorks announce its latest version, the SolidWorks 2015. The tagline they put for the new version, "Improve your Every Day Productivity", gave me the impression that the new version could do 3D modelling easier and faster compared to their previous version.


I personally have not tried this new version yet, but looking at their promotional video, it seems that they have improved pretty much on the sketch mode. One drawback I realize for the previous version of SolidWorks is difficulties on creating 2D sketch, especially for the first feature. I would typically start of with creating dummy scale to approximate how big my sketch is. Other competitor, such as Autodesk Inventor, in their latest version of Inventor 2014 has come out with auto-scale feature which I think is a very useful function.

Another feature they mention on their promotional video is the ability to use table for pattern, which gives flexibility to customize your pattern. Even this is a great feature, I wouldn't call this a revolutionary things as other software such as Pro/E (which is called Creo now) already has this feature from quite some times ago, though it is not that easy to use!

On a personal view, I believe that the 2015 version will improve overall user experience without losing their main ace, the user friendliness. Contrary to earlier version, this version will also give option to more advance user to create their 3D model using more complex feature. If you are interested to participate to get the trial version, visit their main website and just express your interest!

SolidWorks - Radius/Diameter Dimension on Revolve

This time I will share a simple tricks that can be useful when  using Smart Dimension in SolidWorks for Revolve function.

Sometimes, we wanted to specify the diameter of a certain part, while on other occasion, we want to specify the radius. Even radius can be easily obtained from diameter, by dividing by 2, on certain dimension it can't be easily achieved. Using calculator might waste a little bit of your time.

The tricks below will show you how to convert diameter to radius without even doing a calculation.


  1. To start off, you need to have a center line as a center of revolution.
  2. Draw a profile that you want to revolve.
  3. Using Smart Dimension, place a dimension between the center line and the sketch you want to give the dimension. Placing the dimension on the same side of the sketch would give you a radius (on the image below is on the right side of the center line).
  4. To convert it to diameter, simply drag your mouse to the other side of the center line before you place the dimension.
  5. That simple tricks would save you a little bit of time!

SolidWorks - Customizing Your Own Keyboard Shortcut

One good thing about SolidWorks is that it is very customizable. Users are able to assign or customize their own keyboard shortcut. With that, users can assign certain hot keys on their keyboard to their mostly used features. By default, SolidWorks have assigned certain hotkeys, for example "E" for extrude, "Enter" for last used commands, "Ctrl + N" for New File, etc.

Customizing your own keyboard shortcut can be done following these steps:
1. Launch SolidWorks and click New > Part. Search for the Options button on top, click the arrow besides the icon, and select Customize.
Note: The Customize would not appear immediately when you launch SolidWorks. You need to create part/assembly/drawing in order to access this function.

2. On the Customize window, go to Keyboard tab. To change any hot keys, just click on the Shortcut(s) column, and press your own hotkeys. Note that you can input combinations of hotkeys, e.g. Ctrl + s, Alt + N, etc.

3. Click OK to confirm.

SolidWorks Tutorial - Pen Cover

This time round, the tutorial I made would be to model one part of a pen, which is its cover. The complete set of assembly however, can be downloaded from here.

I chose to make the tutorial only for one part as you can learn how to use several features in this tutorial.


Skill learned: 

Revolved Boss/Base, Revolved Cut, Fillet, Sketch Relationship


Final Product:













Tutorial:

  1. Open up SolidWorks > New > Parts.
  2. On the Model Tree, right click on the Front Panel, and select Sketch.
  3. Select the arrow besides line, and select Centerline. Draw a vertical line passing through the origin. 
  4. Select line, and draw a shape of object that looks like shown below. 
  5. Select Smart Dimension, and give the dimensions as shown below. Note that all dimensions against the Centerline are all for diameter, instead of radius. Read here for a note of how to give diameter instead of radius on revolve. 

  6. Click Insert > Boss/Base > Revolve. Or alternatively, click on the Features Ribbon, and select Revolved Boss/Base. You should see a preview as shown below. Click the green thick button (OK) to confirm.
  7. Right click on Front Plane, and select Sketch.
  8. Repeat step 3, draw a vertical Centerline passing through the origin. Draw 6 rectangular box as shown below.
  9. Hold down Ctrl button, and select all 6 inner edge of the rectangle. On the left dialog box, select Colinear and Equal.
  10. Give the dimension of the rectangular box as shown below. Note that the spacing of the box (1.5 mm) is the same for all. 
  11. Click Insert > Cut > Revolve. Or alternatively, click on the Features Ribbon and select Revolved Cut. A preview should appear. Select the green thick button (OK) to confirm. 
  12. On the Features Ribbon, select Fillet. On the left dialog box, adjust the radius to 1 mm, and select the edge shown below. 
  13. Add fillet on the edges of the revolved rectangle, adjust the radius to 0.1 mm and select all the edges as shown below. Note that you can select the surface (highlighted on the rightmost selection) instead of selecting the edges one by one. Read here for explanation of the selection.
  14. Congratulation! You have completed your model!

SolidWorks - Zebra Stripes

Zebra Stripes. Some of you might have come across to this function and was wondering what the purpose of this function is. For those who haven't seen it yet, you can access this function from Evaluate ribbon > Zebra Stripes.


The function of zebra stripes is to simulate the light inspection. This inspection is typically used to inspect the surface of a car. Light inspection is done by shining parallel lights unto the inspected surface. The reflection of the lights would form a contour on the surface, making any imperfections easily detected.

When the zebra stripes function is activated, a contour profile is shown on all surfaces of your model. Even this function might not be particularly useful for solid modelling, it is a very useful function to make good surface model.

Below is an example of using the zebra stripes function to identify your surface model.

Zebra stripes - bad model
Bad Model. Notice discontinuities of the stripes between top and bottom door panel.
Spiral or circular pattern indicate that the surface has dent/bulge

Zebra stripes - good model
Good model. Notice how the stripe flow smoothly between the front and rear door panel.

Gallery - Nissan Fairlady 350Z in SolidWorks

All right, this is the first car model that I created in SolidWorks using surface modelling. Wasn't really the best car to choose for the first time. Pretty complex shape and lots of curvature. I haven't really learnt how to create smooth surface modelling back then, so there's pretty much disconnected surface in this model. But overall, it was pretty satisfying after completing my first model :)

Enjoy!

SolidWorks - Creating Plane

On the creation of new parts, by default the parts would have three default planes automatically created by SolidWorks, which are the Front Plane, Top Plane, and Right Plane. 

If required, additional planes can be created by selecting Insert > Reference Geometry > Plane. Or it can be accessed directly from the Features ribbon. 

To create plane in SolidWorks, users can specify up to three references to create the new plane. The reference can be either an existing plane, surfaces, edges, axis, or a point. A few example of commonly used reference is shown below.

1. Offset from existing plane

Only one reference is required. New plane that is created is parallel to the initially selected plane at specified distance. Commonly used for loft feature.

SolidWorks Plane Offset
Plane created at 50 mm away from the Top Plane

2. Plane at an angle from existing surface

Two references are required, one is a plane or a surface and another is an axis or an edge. The axis/edge selected would be the intersection of the two planes.

SolidWorks Plane Offset Angle
Plane at 30 degree angle from the selected surface

3. Plane that pass through three points

Three references points/vertex are required. The plane created will pass through all the three points.
