A statistical question about your own method of using SolidWorks:
When you make a quote in a drawing, what is your usual way of proceeding?
1. Intelligent quotation (i.e. all dimensions are controlled)
2. Dimensioning by Model Object
with your personal comments on the subject
Yours sincerely
Hello Alain,
I'm between the 2! :)
I import as many dimensions as possible from the 3D (so I get the dimensional tolerances put during the design), but I complete with dimensions in the 2D. My 3Ds are made with the minimum of redundant dimensions, with a maximum of sketch relationships.
Typically, what I have to add on the 2D are the center distances (yes I could put them in the 3D in piloted ! ). It can be much more, it depends on the parts.
There are also "lighter" dimensions accessible by 2D, such as chamfers and symbols for drilling.
For me, 3D and 2D are not rated in the same way. I don't have the same need in design as there will be in production.
There you go. :)
So personally, I use intelligent dimensioning.
On the one hand because I started learning this way and it's fast because I never have a lot of odds to fill.
Secondly, I find that the object of the model gives way too many ribs, or some that interest me lack. And removing them by hand takes as much time as putting them on manually.
I may be in the era, but it's my way of working.
@Bart, maybe you know, instead of deleting the imported dimensions that don't interest you, it's better to hide them (View/hide/Show annotations, which I have advantageously coupled with the letter "A" on the keyboard)
That way, when you reimport the objects from the template after a change, you don't have to start deleting the entities you don't care about!
That said, I agree with you for simple sheet metal parts, there is much more to throw away than to keep!
:)
So in my case, it's weird:
- I started parametric 3D with ProE, I had been taught (and I thought it was great) to import objects from the model.
- Later, I switched to SW and the house habit was to create the dimensions (and I find that SW's object import function is less intuitive than ProE's).
In use, with hindsight, I don't feel like I spend more time creating the dimensions rather than sorting out and repositioning the ones I keep. And I agree with Benoit.LF on the fact that in design (I'm in a specialized machine), we often place construction dimensions that will not be those of the dimension (especially the starting dimension).
Another point in favor (for my use) of the "smart" dimensioning is that in case of modification of the part, the obsolete dimensions remain displayed, it serves as a memo on the modified areas (we work with several people).
I prefer to put my sides along. Choose myself which one goes where. As said before, the modeling dimensions do not always (or even rarely) correspond to the dimensions necessary for manufacturing.
And then, I find that placing your own ribs gives you the opportunity to think more seriously about your tolerances. With the automatic bet, I feel a bit like I'm going to miss half of it... but that's just a personal feeling
For me, intelligent rating because the one by object of the model gives too much information and two, if the sketch of the object was not well rated or does not respect the tolerances, you have to start all over again.
On very simple parts where the tolerances are "blurred" it's good but on a part with multiple machining of precise tolerances of drilling axis etc it becomes very quickly catastrophic.
Smart Scoring is
what is + clean and + readable for the reader
and facilitates visual organization via the appropriate tools

Hello
For my part, quotation by intelligent coation.
In my 3D the dimensions I put are not necessarily the most judicious for my shots.
Hello
Personally, I only quote in smart dimensioning, I don't import any dimensions from the 3D. I tried, but I waste way too much time to delete (or hide) the dimensions that don't interest me. Also, I like that there is a gap between my dimension line and the dimension line, but with importing 3D dimensions, systematically, the dimension is taken in the middle of the segment, so I spend my time shooting on the dimension lines.
Otherwise, there is also the import of dimensions made via "DimXpert", I also tried this solution, but I was not more convinced than with the import of 3D sketch dimensions.
Hello
Same as (almost) everyone, I use smart ribs. When I'm designing, I really don't pay attention to the ribs that I would need on my 2D.
So I might as well start from scratch on my 2D but be sure of the result:)
Sorry, but I use the object import of the template more.
Because the customers who retrieve the files prefer to choose to make the changes: from the mep or from the 3d.
By the way, how do you make your changes to find the dimensions that go well in your model?
Hello
For my part, I use both but I try to use the 3D dimensions as much as possible, even if it's a more tedious one, especially with the cross-sectional views that don't go through the sketch plane...
I still find when using the dimensions of the 3D the modifications and the updating of the plans is faster.
Just an important clarification, when I import the objects from the model, I do it by function, and not on the whole model.
It allows you not to be overwhelmed by dimensions, and to "orient" the dimensions of a function towards the view that is fine!
For us on our platform, we try to use the dimensioning by object of the model as much as possible.
When we design the part, we already think about the MeP.
After a while, I can say 80 to 90% of the ribs are brought back from the MeP and we save time.
Thank you for your many answers.
I will close the subject by rewarding the first answer.
It would have been interesting if everyone had specified the type of design they are working on (consumer products, special machines, tools, etc.)
Thank you, it's always very interesting to discuss our practices

@Alain, it's on a special machine. Sheet metal parts, mechanically welded, machined.
