How to Read CAD Drawings?

• Thread starter theitcrowd

Hi,

Okay and so I am struggling again with CAD, I need help on how to understand and visualize 2-D drawings to make three-D drawings using Solid Edge

Are at that place any websites or places where I can empathize these drawings for e.chiliad. I am making a model of a screw jack at present and I accept the meridian ,forepart and side view and a few dimension simply I don't empathise how to visualize ii-D to make it 3-D ?

I hope I have been descriptive enough :)

Thanks

This is something that some people seem to exist able to practice automatically while others never finish finding it hard.

You kind of have to first know what 3D things look like in second. Eg a cylinder may be a rectangle in two of the views and a circle in the other view. Then when you see circles you tin check the other views to find if they are cylinders and how long they are.

You might get used to it past looking at second drawings of things y'all already know in 3D. One way is 3dcontentcentral.com You can download 2D and 3D versions of all sorts of parts.

Another way to piece of work on such things is to grab a handy-dandy point and shoot camera and choice a few objects to take some pictures of. Take pictures like you take for your ball screw and see if you can see how you would construct whatsoever item yous took a motion-picture show of.

Practice, practice, practice.

Your best bet is to actually actually typhoon up unproblematic objects you tin can run into in 2nd CAD. Not only volition you become a better idea of the 2D to 3D visualization, but your drafting skill will improve.

It'll be vital for when someone inflicts autoCAD on yous.

Good word "inflicts". And I think information technology holds truthful for every CAD software out there, from autoCAD to CATIA and beyond.

In the days "before CAD", when the only way to draw anything was on newspaper, learning this skill was a primal function of learning "engineering drawing", and yous got to practise it the whole fourth dimension y'all were drawing anything.

If you desire to larn this "properly", endeavor to find an introductory textbook on engineering science cartoon from the 1960s or 70s that doesn't mention computers, and work through it.

Of course reckoner software for 3-D drawing and visualisation has great value, only one of its drawbacks is that people tin can get started and (plain) progress for quite a long mode without e'er having to face to learning the basics.

If you accept some iii-D drawing software, if might be useful to construct 3 faces of a rectangular box, "draw" your 2-D drawings on those faces, and the "extrude" the drawings through the infinite "within" the box, to run into how they fit together to make the solid object.

Exactly what I experience, I retrieve going direct to CAD is making me feel similar its really hard. We need to know the basics , however at that place is admittedly no time to get through whatever books now considering I have 6 subjects and iii labs right at present and so the just manner is to keep practicing and my exams are in two months.

Yes I apply Solid Edge, and yeah I have been trying some drawings and its going pretty good.

I guess that's the simply manner to get it washed.

Cheers for your assistance and the others will keep you posted!

Thanks,

I wish I was the type of person who could visualize it directly, but none the less I guess if I proceed to practice I tin can do it.

Thanks for the website sounds great. Will have to keep checking them out.
