Does anyone know any good reference for some advanced part modeling exercises? I am looking for something similar to Model Mania but more complex, maybe with more surfacing features.
Have a look at this one: Complex Surfacing Speaker
OR this one Surface Modeling a Car
here are good surface tutorials

Thanks for your suggestions guys but I am looking for part modeling exercises similar to model mania and SolidWorks Certification exams where all dimensions are specified and you have to generate the part.
3hrs time limit.
Clock starts when you open the pdf.
(I have a bunch of similar problems when you finish this one.)
Efficiency in technique for future editing counts in the score - so don't simply cobble together first attempt and attach that with minimum time.
Use the full 3hr time limit. (and them some if needed)
Today I finally got to work on the problem you sent.
I spent about an hour experimenting with the first attempt and found it very tricky to determine the helix that would center the holes on the helical face since it was off by 2mm from the origin.
All changed when I found that I can use equations with a helix by clicking the helix curve.
I stopped there and took another stab at it from scratch.It took 46 mins for the modeled part and drawing.
The helical sweep and holes are modeled as "parametric". You can change any dimension of the helical feature and the cut and hole pattern will update.
Attached you will find the model part and drawing as well as a picture illustrating the flexibility of the model.
I had a lot of fun with this model and learned quite a bit.PLEASE SEND MORE!
Do you have access to a Engineering Graphics textbook?
Mine is chalked full of simple to complex parts. I love it
Here you go.
Tricky but easy when you know the trick.
(BTW - you do not need to compress (rar) the file when attaching here - it is automatically zipped. I do not have a "free" rar extractor installed on my clean SolidWorks machine as I have had bad experience with mal-ware. Win OS, CAD software and MS Office is all that gets on my machine. I don't have any of the typical problems that I see posted here regularly.)
Tip: Mark each dimension with a highlighter as you account for the feature. Carefully compare your 2D drawing to the image upon completion of the model.
I think I found this on these forums, though I can't find the post now, but I thought it was fun
Hi alex, I want to know how you got that 3d sketch to follow the surface for the hole wizard. I am facing issues with that part. Rest i have figured it out myself. My spline wont follow the surface and would offset randomly. Thanks for any help.
This is a great posting. I am looking for the same content. Maybe not more complex since I am still learning, but more models/drawings is a great idea.
I've been working on this one a while and I dont think the loft feature is the answer... Any tips?
Attach your attempt here.

Very nice!! I got a set of drawings for the M1911, but not like these originals. I got about halfway through modeling it before things went south at work. Things are much better now, thankfully. I need to revisit it. I had fun working on it. I need to see if I can find similar drawings to other classic weapons. Maybe a BAR, an MG42, or even a Chauchat LMG if I want to see how NOT to design a weapon.
Tis the JD Stumbling Block
Ah, but were you paying attention - do you know the solution?
Al Griego Hint 1: When you know the solution - it is trivially easy.

I am just interested in modeling it as an interesting bit of military history. It's too big of a POS to make any improvements to it. You're better off just starting from scratch.
Oops, I meant that for @Spencer_Barksdale
..not sure, here's a file to get you or anyone going so we can discuss...
Here is my solution, hope it's right :-)

I haven't compared the mass properties, - it looks good.
But you have done way too much work to get to solution.
Plane1 is not needed - you could have done Sketch13 on the Front Plane.
I would have done Sketch14 on the Right Plane (use the BORN Technique as much as possible and practical).
What was the Delete Face?
Sketch16 could have been done on the Front or Right Plane (use the BORN Technique as much as possible and practical).Consider the robustness of the model in response to change requests.
Sketch19 should be an arc rather than a spline. (My mistake Tangent arc, so it didn't Retrieve a dimension and I forgot to add to the 2D drawing.)
Why 10 Ribs?
Mirror3 is unnecessary, sketch circle on Front Plane and Extrude midplane before adding Counterbored Hole (one feature rather than two Extrudes).
Been 3 yrs since this was posted, I'll try to post a video later today on my technique.
Thank you for that!
Never heard about BORN Technique.... I'm still new to Solidworks.
Will definitely redo part again.
..the rythm, mission and born? (smh)
Hello mr Mather,
I was wondering, what do you refer as the ''BORN technique''..?
I've never been able to handle surface and would like to eventually learn them. I might hit up some of the training files posted here, seems like interesting exercices to begin.
BORN technique essentially just refers to designing around the origin. (AKA) - Designing a part symmetrical about the standard planes or starting your sketch at the origin rather than out in space. It promotes efficiency & helps convey design intent. It should be day one stuff for anyone using SW.
