This is a very easy challenge, so there will be only 1 (one) 5,000 point prize.

 

To win it, find the simplest, most elegant solution (yeah, I know, it is a subjective criterion) to this problem:

 

Remove the slit from the attached file.

 

Speed is not essential to winning this challenge.

Alin,

I can't get the file either.  They may have changed our firewall to not allow zip files.  Can you check by downloading it?

For whatever reason I can get the file now.  It may have been a glitch on my side.  But, it's strange someone else had the same problem.

Very nice solutions, so far. Good job, everyone.

 

It is time for a second suggestion: think about reverse engineering the model. SOLIDWORKS has dedicated tools for reverse engineering.

Hi.

Here is my quick submission.

Some assumptions are made. 1. Model can be symmetrical to the front plane. 2. Is made from 3 operations: Surface revolve, surface trim, thicken.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

I first looked into this method. but if you look closely at the end condition the tangency is lost in the top face.

OK, her is submission #1.

 

I just use boundary surfaces to fill the gap...not pretty, but it got the job done.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

And here is my submission # 2.  I thought of this after I finished the first one.  So I tried it out and it worked pretty well.  Looks just like the one on the right in your picture:

 

I created some comments to explain the steps.

By: Dan Pihlaja  Wed, 15 Nov 2017 14:44:21 GMT
Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

I couldn't get the solid boundary feature to work for me at all with this.  I did it using surface boundaries in my first attempt....but the lines show up.  As for the solid boundary feature, it either kept error-ing out for me or created extra bodies that I didn't want. 

 

Must be a SW 2015.....or a Dan thing.  LOL

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

see my original reply to Jonan. Move face is a powerful tool but in this application it does not yield the desired result. Attention to detail is necessary when using that sort of feature.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

Loving all the different ways!!

My first thought was the cut with surface/mirror approach, but then I thought I'd try something different.  Wondering why the part was hovering above the top plane, I worked out that extruding a 100mm circular surface with 7.5 draught was about right followed by a thicken.  I got the end cuts (surface trim before thicken) from the original geometry.

EDIT: oops just noticed this is incorrect.. a combine subtract leaves extra

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

Newell,

You may be right. I just placed the aforementioned method based on the problem description which was "Remove the slit from the attached file". Furthermore, the move face solution is being used earlier by Jonan Van Asperen. I just reduced one feature (axis).

Cheers,

Siavash

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

Alin,

Here is my attempt for simplicity. The cut make for clean healing on the move face as does selecting both of the cut surfaces. This eliminates the little step on the top.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

Worth a look at 'curvature' in the evaluate functions if you used boundary surface or loft. Loft looks to give better results fixing tangent to faces, boundary looks not so perfect.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

Newell,

 

Thanks for pointing that out.  I would have probably overlooked those little edges too.  See if this sorts it out. I can't spot any loose edges, but I havn't taken the time to do a full on geometry analysis just yet.

 

I'm in the middle of a project in SW'16 just now, but when I have a chance to close it up I'll open SW'18 and have a look at yours and some of the others. At which point I'll probably discover that, like the move face "trick" others have already figured this out too.

Re: The 13th SOLIDWORKS Power-User Challenge - Remove the Slit from the Thin Part (Heal the Part)

By knowing the part is symmetric accomplished e.g. by feature recognition, here comes one.
