Today I found this part in our vault (see attached, SW2017).
Check the design tree, I swear this is not a joke...
I really need to start teaching design intent. (and this forum need a "horror museum" type of post for this kind of monstrosity).
Edit :
Keep in mind that this topic is mostly here to show the importance of the design intent an make a "what not to do" library. And if we can laugh ... that's an extra
Ahhh, Look at all the pretty colors...
Here is one for you. I was given a simple task of changing one of our weldments (weldment in real life not a SW weldment) from mild to stainless steel. No problem except we have difficulty getting stainless in sheets large enough for one of the parts. Again no problem as it laps over another smaller part that I can extend while shortening the first. In doing so I need to lengthen one leg and add another bend. Now we find the first problem. First he didn't use sheetmetal but extrusions. Then he did a thin extrude and just did it blind rather than midplane. Then he needed the part to be 1/4" wider so he added a 1/8" boss extrude to both sides. Then he dimensioned all cuts from the edge which means this sliver of an extrude.
It would have been easier to start from scratch. Fortunately it was a small part. Attached for your enjoyment or here are the pictures.
Here is what I needed.
Oh, and the other part was modeled the same way.
I recently came into contact with a part which does a fantastic job of showing why lazy surface modeling is not a replacement for solid modeling. I'd describe it as a monument to mans arrogance
On first glance it's an interesting looking part, obviously this must have be- wait, wait - are those blue lines on my surface edges? No - no, it can't be -
dear god... what have they done?!
oh lord please no
Surely though, surely the sketches are defined - it must have at least one redeeming quality
nope
Truely worthy of the Solidworks horror museum
Thankfully, i've since remodeled it as a single body
I got one how change the color of the dangling dimension in the system option so "it's easier"...
And I was surprised when Feature-Driven patterning the bolts in the assembly didn't work as expected!

But...but...but, it was already a single body
Being new to this: how are these mirroring done? If I had to use mirroring, I count 2 (1 on the short edge, one on the long edge), not 5
Also, what's the best method to position the holes here?

There is no best method. I will typically create a single Hole Wizard feature for the holes that join two parts. If there is some symmetry and the part connects to two or more of the same part, I might expand that Hole Wizard feature to include the all the holes that attach those identical parts to this part. If the number of holes is exceeds what I can quickly sketch and constrain, I might make a single HoleWizard hole and then use patterns.
Thanks!
So you would define right & left placements either in the sketch or in a pattern, and not use mirroring?
Possibly a new PB, certainly from a Feature Count perspective. From this:
To this:
Previous guy didn't seem to believe in redefining sketches when the geometry needed changing, the Move Face command got used instead.
Oh I think you found my ex-co-worker.
From this:
To this:
That's pretty awesome Dave Laban - using the Move Face feature would allow me to start out Designing a Chair and ending up with a Bed...
It's certainly one of those tools that I always try to use sparingly, unless I know it's just a concept model that will get redone properly for production anyway.
The worst part about the original model was the sketch that was unsuppressed, but didn't actually do anything, that made the rebuild time do this:

That is devilishly good...
I would clean it up just a tad more...
Make sure to Save Face after move face.
John,
That sounds like a power user challenge!
Post a chair model, and the spec's for the bed. Whoever can get there using only Move Face features (no editing any of the original features of course) wins.
The more I think about it, the more interesting, and challenging, this challenge could be. Maybe two winners? Most Move Face features, more in keeping with the spirit of this thread. And, fewest Move Face features, more of a challenge.
I ran across a drawing yesterday that has a 28-1/16" dimension.....for a rebar bend. That's asking for a precision of 1/16" when actually getting rebar bent to within 1/4" is doing pretty good.
I feel like this belongs here. It's the skeleton for a flexible assembly. The size and amounts of various parts change based on the overall size, most calculations are done in sub-assemblies. It sounds horrible, but works like a champ. It's all documented in detail how to change any of the parts as needed down the road.
--edit-- this was not done with "fully constrain sketch" tool
--edit #2-- since this issue has been brought up in a few parts of this thread, the origin is in the lower left corner. Put that pitchfork down. There are drawing views near the origin that need to stay put, while the far edges are the parts that move.

The dimensions on that one look like the sketch was created and then "Fully Constrain Sketch" was used.
I'm not a fan of that tool for anything beyond the most basic of sketches and definitely did not use it here.

I only use it if I am having a hard time getting something locked down. Usually with an imported sketch. Then once I have it locked down I will delete and replace many of the dimensions with relations if possible.
For some this is the only change they will accept.
