Rookie Help Please

[Gno]

Ive never done any Cad work (besides book excercises) and wanted to know if there were a blueprint for producing a cad drawings. like do's and dont's, the basic must haves. Can anyone steer me in the direction to find templates, sample layouts and/or guidlines to follow.

Ive done some searching but havent really found anything.(are templates to be self created?) The book i have doesnt really apply to any real world experience, so i figured id ask you guys. Like whats the process in submitting a Cad drawing to someone? I have some what of an incomplete drawing (attached Below) that i would like to complete and plot so i can send it out to a machine shop.

 

If possible can anyone tell me the goods if any and the bads of my drawing, or if im even headed in the right direction so far. Im open to all comments, opinions, etc.

 

I'd really appreciate any input.

Thanx in Advance

Do you have a job in the CAD field already? Because alot of your guidelines and processes are going to be covered by the companies standards that they have already established. Also if you dont do you know what field you want to get into, alot of these guidelines can change based upon what field your are in i.e. civil, mechanical, structural, electric, etc. If i get a chance to look at your drawing ill try to give you some pointers. But always remember, there is drafter preference, and you may get from point A to B different than somebody, just make sure you get there correctly and effiecently for yourself.

Just looking at your drawing putting it in the order from where they are will help. Like put the front view to the bottom left, the right view to the bottom right lined up with the front view, and the top view to the top left lined up with the front view. It would clean things up if you added center line for you circles. Show dimensions, but do not show the same dimension twice. Try to dimension from one point on each view. I will attach a example in a bit.

 

Here take a look at these:

Here is a example only!!!

Thanx for the advice Jaylo, Im not in the Cad field at the moment, however im lookin to do mainly mechanical, some electrical.

 

 

Neekcotrack, those are some great examples. So the bottom view is not necessary? Front, top, and side ( and iso. for an overall view) or just enuff to annotate the dimensions effectively is all thats really needed? Im gonna try to clean this up and add some detail to it like in the examples.

 

good stuff!

Thanx again guys:)

So the bottom view is not necessary?

You should show as much as is needed. In your case the bottom view is the only place that you see the circular recess, or show that it is a square block. When drawing mechanical parts it helps if you know how to make it, such as....

 

start with square bar. cut to length. radius top. add flats etc.

 

you don't need to know excactly how its going to be made but talk it through with yourself.

[ReMark]

Views normally consist of top, front and one side. Bottom views, as Dave mentions, may be required when an important detail cannot be conveyed by any other means. Then there are the auxiliary views. These would be used to obtain a true-size view of an inclined face. The three auxiliary views are front auxiliary, top auxiliary and side auxiliary. You can even have an auxiliary section in rare cases.

So after taking the excellent advice/pointers you guys gave me, and 6-7 hours:wacko: , i turned out with this (attached). I know its lite work compared to what you are used too, but im actually impressed with were its at for a first project. Had a bit of a tough time with the iso view, but figured it out.

 

Quick question: Can a isometric view be imported/copy & pasted into a 3d workspace so u wouldnt have to draw it again?

 

 

questions, comment, opinions are welcome:)

 

Thanx

Yes, you can copy/paste an isometric view. Just make sure your UCS is in the correct orientation.

 

It is also possible to draw a 3D isometric (which I like to do over the conventional method).
