checklist or set of company standards for making models 7

[duk748]

hello - our company has been going thru hell w/ solidworks ever since we had someone who knew nothing about setting up a solidworks users group to get our engineering group started in 3d cad - the person our so called expert just dumped the software in the engineers laps and said go for it - now we have parts & models w/ sketches under defined, planes & origins all over the map, etc. - does anyone have a set of standards or a checklist that their engineering group follows & is policed by in creating their models such as sketches must be all black, dims & datums on the models so they follow to the drawing , etc. - any help or documents that i could use as a boiler plate to follow for our group would be greatly appreciated - thank you in advance

I think the best practice for 3D modelling is as follows:

1. Capture design intents;
2. Efficient models (less rebuild time);
3. Simplicity.

Best regards,

Alex

Shaggy,

I love the post you put out there... but can you give some clarification on "6.5 Feature creation should be as simple as possible. The practice of adding/removing material when a previous feature’s dimension could have been changed to achieve the same result should be avoided. (No FrankenModels)" are you referring to the actual material (steel, aluminum, etc..) or are you talking about something else? You mentioned a previous feature dimension could have been changed. not sure how a dimension and a material can resolve a feature... what I am missing here?

I am just starting to read through all the items, so I might have some more questions about your post.

Thanks,

Hi Scott,
Paragraph 6.5 is not referring to the type of material the part is made of. I am referring to cutting away some of the model rather than adjusting a dimension. i.e. original dimension on the sketch of a plate is 8" x 6". Later we decide to make the plate 8" x 5". Rather than going back to the original sketch and changing the sketch to 8" x 5" (good practice), the user decides to cut an inch off to achieve the 8" x 5".

The Frankenmodels reference is in regards to glomming on feature after feature, adding material then subtracting it... ala Frankenstein's Monster.

In recent years, I have come across a new feature called "move face." While I see its merits for imported models, my first exposure to it was when an outside contractor used it to adjust a part dimension as described above.

Thanks Shaggy! I completely understand what you mean by Franken models now. I seen that at my last job... I should have called them that when I was there. Maybe that would have caused them to change.... nah who am I kidding, it wouldn't have changed.

Thanks!
