Orientation of holes on a PCD in Isometric

[Vagulus]

Can you attach that exercise here (my tutorials are not intended for beginners).

 

That exercise was intended for beginners . Surface Development. It's completed now.

 

I had a look at your tutorials, thanks, but the ones I looked at didn't show me what I was looking for right then. I downloaded a string of tutorials by Rob Cohee from YouTube. Rob is apparently some sort of Autodesk Guru and I got to see some of the things Inventor can do. It certainly is an impressive piece of software and, for one thing, makes a meal of surface development. But after looking at about 20 of these videos I started to wonder if Inventor is not getting too smart.

 

A lot of software these days seems to be created to do something just because it can be done. Inventor's ability to perform visual wonders, which is undoubted, must come at the price of having those wonders done in the way in which the creators of the software expect you to want to do it. I sense some sort of loss of absolute control of the creation of the image. Then I have to start wondering what if ... ?

 

What if I want to do something out of the ordinary? What if I genuinely want to invent something? What if the artefact I wish to create has not been seen? What if I want to invent?

 

Is it possible that in such a scenario I would be better off with a more (dare I say) primitive drafting package? Am I better off using something more tedious, something slower to use, but something which retains full control of the drawn artefact in the mind of the user? Humble AutoCAD, perhaps?

 

Be assured I am no Luddite ! I will gleefully seize any technological advantage I can. I am just not about to jump to something new because it promises all the bells and whistles only to find that I have lost overall control of the application. I keep remembering that mobile phones were invented for the purpose of making phone calls.

I don't know what old technique or creative process you're hoping to preserve by using CAD software to do things the hard way, but IMO, all you're likely doing is wasting time... but it is your time, so have at it.

[ReMark]

Vagulus: I get the impression you do not know what the difference between Inventor and AutoCAD is so how can you discount its use to "invent"?

....

 

Attach the assignment here.

You have a longggggggggggggggggggggggggg way to go to understand where this (AutoCAD or Inventor) is going.

 

I will gleefully seize any technological advantage I can. I am just not about to jump to something new ....

 

I am 56 yrs old - worked on the drawing board in the last century, worked out on the shop floor as machinist for 8 yrs.

It is time to leave the 20th century behind and join the 21st century.

I demand absolute control.

 

Where do you want to start? Inventor or AutoCAD?

[Vagulus]

For some reason my I can't attach anything.

You can download the DWG file here.

It ain't nuffinck speshul!

[Vagulus]

I don't know the difference. That's why I asked the questions.

That's not discounting Inventor's abilities.

[JD Mather]

....It ain't nuffinck speshul!

 

Do you have a page number from a book that that assignment came from?

Title, author and edition. PDF?

 

Once again I ask, which program do you want to learn? Inventor or AutoCAD?

Once you answer this question we can begin.

[Vagulus]

Made it up.

All my own work.

I hope it's not illegal or anything .

[JD Mather]

All my own work.

 

Either I don't understand the design intent or you didn't complete the solution.

 

[Vagulus]

There are a whole lot of layers that need to be made visible.

You should wind up with a development of the surface of the round duct.

Just ignore Vertical Projection (the orange one).

[JD Mather]

I missed the layers.

But your solution is not correct - you cannot divide circle in top view to get correct solution.

 

Moving on - do you want to learn AutoCAD or do you want to learn Inventor?

[Vagulus]

You got me there!

Is this what you have?

How do you get the intercepts with the flat surface of the square duct without dividing the circle?

 

On the other matter, any decision between AutoCAD and Inventor will be predicated upon the answers I get to the questions I asked about doing things out of the ordinary. I have read a few howls of derision, but I have not had considered responses to those questions. Inventor remains very much a pig-in-a-poke.

AutoCAD

 

[Vagulus]

Wow!

This appears to be an AutoCAD 3D solution.

Sad to say I haven't moved on to that yet. I still have a thing or two I 2D I want to be more confident with before stepping into 3D.

Thanks for the preview. There is light at the end of the tunnel !

i moved to 3D about 6 months ago, Vagulus. took mebbe a month to get up to speed.

imo it is actually a lot easier than 2D.....you just have to plan your route a bit more as sometimes changing stuff can be a pain and there is often several ways of achieving the same goal - some incredibly simple. some complete 3D duct parts i do are literally 5 or 6 clicks and look awesome).

you're actually modelling the real thing, not a representation of it. As JD said - you have 'the truth' right in front of you.

2D is drawing board stuff. R14 anyone?

If there was a soundtrack to this thread it would be "Dazed and Confused." And that's despite videos custom videos demonstrating the ease with which 2D views can be extracted from 3D models as demonstrated by nestly. Have you considered giving up on CAD and going back to the drawing board? Perhaps as a substitute you could use a tablet and stylus with SketchUp Pro. That may be more to your liking as it seems you feel too restricted by AutoCAD and you fear that Inventor is going to take over your design process.

Maybe you should book a good book while you're at it too. I recommend Mechanical Drawing by Frederick Ernest Giesecke.

 

Another book I would recommend is Engineering Drawing by Thomas E. French.

I've never seen more thorough information in a sarcastic response! Made me chuckle :-)

Give the guy a break, it's the beginners forum

[ReMark]

Yeah, the world is a cruel, cold, dark place. Cry me a river.

I didn't realise 2d isometrics were still a thing

[ReMark]

The concept is still discussed in Ancient History class.
