2D drawing nearly dead?

[321GO]

Hello Guys,

so what do you think? Is there still a future for (mechanical) 2D drawings and subsequently for the associated industries?

Are businesses today not elliminating this "in between step", and directly transferring 3D to there machines? Since i'm still doing a lot off these 2D's, i'm wondering if i'm working on steam train technology?

So what do you guys think? How many of you still use these and will continue to use these? Is there something that makes 2D drawing somehow "supperior"?

BTW i'm purely talking about the mechanical sector.

Thank you all in advance!

KENAT,

Change from linen to tracing paper does not require a radical change to the way you do design. I think 3D does.

I am trying to find a set of Rapidograph pens for my niece. She likes drawing Manga. I have my own set which I have used for both artwork and drafting. They are no longer in the stores here in the Toronto area. I cannot even find inks in bottles suitable for reloading the pens. The clerk at the artist run store I visited, told me that they cannot find the matte mylar any more.

My niece may be getting books for Christmas, again.

drawoh, true, all kinds of supplies are going missing. Engineering pads, colored lead for lead holders, who knows what all.

Regards,

Mike

drawoh, matte mylar... that's a blast from the past! I remember razzing my friends that were still on vellum when I was using that mylar with plastic-leaded mechanical pencils. "Ha ha, you still need to use a scum bag..."

Have you read faq731-376 to make the best use of these Forums?

I don't know, switching from ink to pencil etc. must have upset a few oldschoolers.

Pah, what about switching from scalpels on aluminium to graphite on mylar?

Bet that made people smile.

I really miss those sand paper pencil sharpeners. They really came in handy when an emergency nail file was needed.

Was ink ever used systematically for mechanical design? Why go to the extra trouble if you do not need presentation quality?

I have done ink on mylar for some installation drawings for our customers. I used my Rapidograph pens and a Leroy template. They looked great until a co-worker changed something with his pencil and his messy printing. It is a good thing Rapidographs are not deadly weapons, at least, while loaded with ink.

I never did a linen drawing from scratch so can't be sure, however when amending/revising them you had to use ink - pencil didn't really cut it. So you better get it right.

Somewhere in the middle of this creo elemets/pro video they demonstrate (full) model based definition. Maybe some of you find this interesting.

asme y14.41 lays down the ideas for MBD with annotated models.

However, frankly, it doesn't seem very user friendly - this has been discussed before.

Plus it relies on everybody having an interoperable data exchange where they can get all the information from the model - not just a dumb solid.

This is made to work for some aerospace & automotive supply chains - gets more tricky for smaller places which can't tell their vendors which CAD system to choose.

However, all this has been discussed before in one or another thread see my 4 Oct 10 20:22 post which has links to lots of threads about this type of thing.

Probably going the way of my 2D TV??!!

I found Rapidograph pens!

The store I called that claimed they did not have any, had some. I even found the squirt bottle for the ink. If you are in Toronto, Canada, you search Curry's, and you ask a senior person where everything is.

The only remaining problem will be how my sister is going to get india ink out whatever her daughter spills it on.

I am sure that 2D will still be alive and well for some time in the construction industry.

Most of the guys on site have enough problem understanding a 2d drawing let alone a 3d one. Easier to understand the concept, harder to understand the detail.

 

[cranky108]

So what units do we use for 3D drawings? Feet, Ohms, or something else?

 

[drawoh]

cranky108,

Drawings are 2D!

One of the benefits of SolidWorks is that it knows what units you are using, within reason. You can model parts in 3D 100mm wide by 6in long by 10mil thick, if you want. My understanding is that SolidWorks works uses meters as its unit of length. It knows the conversions.

Well, having had some limited experience with solid modelers I note that the graphic represenation is ALWAYS 2D due to the fact that computer montors are, like paper, flat.

Regards, and happy New Year.

Most of the drawings I work with are unitless, although the mechinical ones could have units, but we don't use units for schematics, logic drawings or R-X diagrams.

So how can anyone say 2D is almost dead?

I also struggle with drawing programs not being able to handle log-log scales for time-current diagrams. And different scales for X and Y in profile drawings.

It sounds like that 2D is only dead in your world, while the rest of the fields these programs just can't cut it.
