Hey people. I am really stuck on my first year autocad project, we have to pick an object and model it using the 3rd angle view. I was wondering here if anybody is able to help me, I know so little about autocad. The lecturer has given us hardly any help and everybody is stuck! I have tried in vain to search on the net for tutorials and such that might be able to help me. This is worth 20% of m grade and due in, in 3 weeks and I am really starting to panic.
I am basically looking for a book or a tutorial which I could just copy. The object must be fairly complicated, the more complicated the better the mark. Any autcad pro's out there that could help me?
 
Can't help, sorry... but have you tried the local library for an "Autocad for dummies" type book?

I'd definatly be speaking to my lecturer if he expected me to hand in coursework relating to stuff he hasn't taught properly.
 
I'm pretty adept with it, it helps if you're good at technical drawing in 1st place (i.e. drawing by hand) as then you can understand how to construct the drawings.

Are you starting from scratch?
 
We have to draw a 3D model and create a 3rd angle view of it. I am really stuck as i am such an autocad novice. It is Autocad 2006. I was looking at drawing a drill but I am finding it so hard to do. My next idea is to do my house as I think this will be easier because it has no curves etc. Just straight lines. Ideally I am looking for a good example that I could use, that has a thorough explanation of everything too.
 
well a house is a good idea.

start by modelling the whole house.

use the autocad help for instruction. when you get to a point you dont understand come back and ask. the help is quite comprehensive :)

once you have your model then we can discuss how to make the dwg.
 
Do you mean you have to create a 3D model in AutoCAD (not simulate a 3D object but actually create one?)

If so this is a lot more difficult than standard 2d drawing.

And will take more than 3 weeks to learn to do a good one !

2D and 3D are totally different kettle of fish. 2D is basically all trim, cut and extend. 3D is that and then some, with a new set of commands.
 
As above, get your 3D model sorted first; something like a building/house as already suggested would be good.
Try not to use arcs or curved edges if you are a novice - they're a right pita as you really have to know what you are doing when you change the UCS (user co-ordinate system) settings to get certain objects to appear in the correct x,y,z plane - AutoCAD is a pain in this respect because unlike say 3DMAX, many objects like arcs and ellipses etc will only draw in the x,y plane and not in the z axis, so you and up having to change the z,y to represent x.y to draw these objects... if that makes any sense. If you've tried to draw an arc in 3D in CAD you'll know what I mean.

Are you doing wireframe or solids? If wire frame you will have tp attach a surface or polyface mesh (iirc). To do this without getting really confused keeping your wireframe and your meshes on separate layers and colours is an absolute must.

Do you have a drawing template set up? A titleblock with name, date, project etc and a number of viewports. Setting upo the viewport projections is a doddle; double click in the Vport then pick the view you want to see from the VIEW / NAMED VIEW toolbar (ie. TOP FRONT LEFT RIGHT SE Isometric NE Isometric, or whatever) or dialog setup box (this last can be dome when using the named view ports dialog setup box from the dropdown menu - VIEW\VIEWPORTS\NAMED VIEWPORTS.)




On the other hand if you are just doing a 2D schematic with multiple views then this is really easy compared to drawing in true 3 dimensions. Example you have a break disk and want to show how it looks for dimensioning -
1. draw it in plan view (looking down from the top)
2. turn the disk so you are looking at it from the side and draw it in cross-section (side elevation) making sure to keep the plan and side elevation aligned with each other with construction lines.
Use your viewports in your paperspace template to show the plan and side elevations respectively...
Voilà! one drawing with a third angle projection.
 
I have decided to do a drill as a test piece before I begin my coursework for real. Would anyone be willing to do this for me? I would be so grateful. I dunno perhaps someone here is bored and a bit of a cad pro or just wants to show off their skills.... I can send pics of the test object.
 
Look mate, we'll help you learn but there ain;t no way anyone here is gonna do it for you. That's cheating for you exam and you don;t help yourself in the long run.

I had to teach myself how to use AutoCAD but it was worthwhile as I'm now quite good and ppl now ask me for help. Perservere - it'll be worth it :)

Yeh it must be cheating for my exam actually, an exam which I do not have unless my lecturer has told you something that he has not told the rest of us. I was asking someone to draw the drill to show me how to draw in 3d, my chosen piece is to draw my house anyway. Read before you reply mate.
 
No, I am sorry. I am just really stressed about this and am frustrated by not being able to understand how to do this. If I am stuck on maths I read a book and learn it very quickly.....but this is different and I am stressing out.
