Unless the unconstrained line has snapped to another edge / feature without the user realising. Then it can move all over the place depending on what happens with the rest of the model.
Agree and disagree, every project has a unique identifier, it's not hard to work that into the filename conventions.
I really hate it when people take the easy route instead of a proper route. I've seem complex models that ended with a cut-extrude to remove everything and then a few features to rebuild a model
Set the sheet metal k-factor to 1!
Hiding each and every plane-origin-axis-sketch (2D and 3D) in every model on a feature tree level, no matter if it's parts or ASM's because "it makes for a too cluttered look".
With as result that Shift+S or Shift+P or Shift+A become utterly obsolete.
Unnecessary dimensions, especially duplicate dimensions, unlinked and buried
Even though there is no one other than me here doing design work, it's just opening old files and trying to decipher what happens, so people to stay off of Jim Sculley $hit list -
- Name your Sketches and Features -
- organize the design using folders,
- try to do every design intent the same way, (it might take a little to learn your method, but if your consistent then eventually it's easy to modify designs.
- use Custom Properties at the part or assembly level (here it sucks that the little bit of custom properties used were in the drawing, so if and when I need to do a new drawing there's nothing connected to the part or assembly so I have to re-enter all the custom properties again),
- create and maintain notes in the part or assembly files that have dates and what was modified etc, even if you use a REV system,
- Don't create circular rebuilds.....
EDITED - and for Jim, don't use extra sketches for Hole Wizard - (oh, if he could only see how easy it is to do it that way though)
Dave Laban's post about separate notes reminded me that when they first started with SW here whoever set up the sheet formats made many of the notes separate when they didn't need to be. For example, the text "Scale" was one note, and the actual linked sheet scale text was a separate note. And "Project" was one note, and the actual project number that's linked to the Drawing's custom property was another one. It made it much more difficult to get them aligned properly when editing the sheet format, and sometimes caused overlaps if a number or name was longer than usual. I'm ashamed to admit that it was only within the last month or two that the light bulb came on and it occurred to me to combine those into single notes, with the text center justified, and then center the notes in the title block box. I cringe when I think back how much time I've spent moving them around in the last 9 years.
Or models where features are added, only to be completely removed by a later feature. I understand that during the design process models evolve and change, but there is a point at which you should just remake the model using a more sensible approach.
Even worse, redundant dimensions on drawings. I have seen drawings where a hole has four ordinate dimensions to it.
1. Blue lines.
2. No use of obvious symmetry.
3. Wack and hack modeling.
4. Don't know where they saved their design.
5. Angle dimensions out beyond 1 decimal places.
6. Reboot SolidWorks to get out of a selection filter (that they don't know how they got into in the first place).
Tapped holes modeled at major diameter size rather than use tap-drill size.
Trying to 3D print cosmetic threads. (my reaction - can't you see that they aren't real?)
Auto-dimensioning of sketch (Fully Define Sketch) (But you told me no blue lines....) (I also told you to use logical dimensions - we (you) can't make anything out to 8 decimal places.
The term "Design Intent" - was the hardest thing for me to learn and had many a process that you go back and pull your hair out, saying why - you can change anything without everything blowing to smithereens - not only is bad design intent hard to change, its also a data cesspool...
The issue with "New" design is the ratio of what you make and what you end up keeping, my ratio is 4:1 or close to it. Where you make four models, throw away three and keep one.
Making a sheet metal part by basically hogging out a block instead of starting with a base feature and adding flanges really ticks me off. We have a perfectly good sheet metal tool.
1. Refuses to learn any keyboard shortcuts (CTRL+C, CTRL+V)
2. Refuses to use mouse gestures
3. Refuses to change mouse sensitivity which requires said person to lift their mouse to move across the screen
4. No use of symmetry
Just having the individual notes as separate entities drives me nuts. I would lose my mind if I saw a drawing with separate numbers as well. Good Lord!!
