Hello SOLIDWORKS Power-Users and welcome the 29th SWPUC!

 

The Surfacing Power-users from the forum asked for a long time to receive a surfacing challenge. Well... here it is.

 

One of the most common tasks for a part designer of complex organic shapes is joining the main surfaces of the part with nice flowing blends. Let's brainstorm together on several topics:

 

- what defines a successful blend

- what are the best ways to create blends for specific cases

- what are the best tools for the job, including pros and cons.

 

There are multiple articles and presentations available covering these topics, so I suggest Googling (is this a word?) the following keywords: Matt Lombard, Mark Biasotti or Andrew Lowe

 

What makes SWPUC 29 special is that we have an Elite Surfacer Judge, who agreed to use his expertise to pick the winners. Many thanks to Paul Salvador for agreeing to judge this challenge!

 

Also, many thanks to Jim Steinmeyer who donated a lot of points for the winners of the challenge!

 

Thanks go also to Galen Woerner who gave us the idea and the model for the challenge. Read more about his original question in this thread: Please help with complex fillet .

 

And now the challenge:

1. Download the attached Parasolid file: SWPUC29.x_t.

2. Import it in SOLIDWORKS and heal any topological errors.

3. Read the initial post in this thread to understand the initial design intent of the user: Please help with complex fillet 

4. Create a blend between the surfaces, as per the information shown in the thread from step 3. Use your imagination about how the end result should look like. A few factors you might consider:

  • Curvature continuity across the edge
  • Surface quality of the blend
  • Elegance of the solution
  • Robustness of the solution
  • Full comments of all steps:
    • how to create reference curves
    • how to heal or split existing edges
    • why you used one tool over the other
    • pros and cons of various techniques you tried

5. An example of a quick and dirty solution can be found here: Alin - Quick and dirty blending. Also attached. Of course, your solution will be much better than the one from the video.

 

6. Upload your fully commented model to this thread before 12 pm EDT on the 31st of July, 2020. If you submitted multiple solutions, please tell Paul which one is your favorite.

 

Paul might have other criteria for judging this challenge. I will let him take over.

 

Prizes for SWPUC 29:

1. First place - 10,000 points

2. Second place - 5,000 points

3. Third place - 2,000 points

 

Good luck!
