problem with drawing a solid model with autocad 2013

[RoseMari]

hi,

it's my 1st thread here, and hope you can help me with this issue

 

The problem is about drawing a solid model like the one in the attachment, and I have problem with the triangle, I tried a lot of things, but unfortunately it's not the same as it should be

 

you can see my work in the attachment, so please help me with it by explaining my mistakes.

 

and one more thing, as it's my first time with these kind of drawing I need to know what's the meaning (10 Drill, 20 C'bore) for a circle and how I can do it you can find it in the attachment

 

and sorry for bothering

 

have a nice day

Please check the sketch below - the parts in blue can be easily draw, next just do two lines from points (1) and (2) using the Tangent Osnap mode. Trim the unwanted parts and call PEDIT to create a closed contour. Apply PRESSPULL or EXTRUDE command on that shape.

I believe that this is what you need to model there:

 

 

Just draw on top plan two cylinders (CYLINDER command) or alternatively two circles and apply PRESSPULL or EXTRUDE on them. Call SUBTRACT next to extract them from main part and therefore get the holes.

[ReMark]

MSasu: What about the end defined by the 6 & 63 dimensions? I think you missed it.

[RoseMari]

thanks alot I will try what you said

[MSasu]

ReMark: In fact I was thinking that that part will be subtracted at the end from the entire solid, but for sure it was better I least to mention this scenario.

[ReMark]

Yours should look similar to this I believe.

I did this same drawing in college. The book, at least in my case, assumes you already know what is meant by c'bore. Any time you see "c'bore" it is usually refering to the bigger of the holes, and should be accompanied by another measurement defining the depth. in this case, 6.

I don't have the book because the Dr. don't want it he just explain some of technique with the engineers to us and gave us class works and home works that's all, but he didn't say anything about c'bore and drill

how did you do it please explain

 

look what happen to mine when I try to subtract

 

[MSasu]

Seems that the slope line isn't tangent to the circle.

Also, how much did you extruded the back part (sketch from post #2) - 10 or 19 units?

[ReMark]

C'bore = Counterbore. It's a term used in machining.

 

How did I do it? Unfortunately I'm not at my CAD computer and won't be for a while. Everyone has their own way of creating the necessary geometry so my method may be different from yours. The more one is familiar with the commands at their disposal the more efficient they can be.

Re: Your 3D model.

 

What exactly did you subtract? What did you subtract it from?

 

It looks like you mis-judged the extent of the triangular section. The sloped line should have been tangent to the semi-circular top.

[RoseMari]

that's what I get finally

 

 

please tell me it's right and there is no mistakes

that's it , it's my mistake , I didn't know which point on circle should the line touch

 

thank you

[RoseMari]

and one more question I want to add my name on my drawing, but it's not clear

my Dr said we should use tools > new ucs > face --->>> and I did it using autocad 2009 at college, but @ home using autocad 2013 it seems impossible

 

so please tell me how can I do it

Here is my try:

RoseMari, I see you have a lot of help from others, I just played a litle bit with your drawing. The text is cut from the solid. And I used Solid Works.

For sure that isn't the way your instructor expects from you, so wait the advices from people using the software you use. As I mentioned before: I just played some.

[ReMark]

Add your name on the object itself? I suppose you could use the IMPRINT command although there is another possibility that comes to mind using text that has been exploded. I'll await you response first.

[ReMark]

My feeble attempt yielded this using AutoCAD. It wasn't quite as easy as I may have lead you to believe.

 

I had to use the Express Tools command called TextExplode to first explode the text. Then I created regions of each letter. Note that in the instance of the 'R' and the 'O' I had to use the Subtract command on the inner parts of the letter. Next I extruded the letters into the block and then I subtracted them thus "cutting" them into my solid. The red that you see was done using the Color Faces command.

 

I can't see how your teacher would expect the students to know this technique. It is probably much, much easier to do something like this in Inventor or Solidworks.

[ReMark]

that's what I get finally

I think you may have gotten it RoseMarie. Nice job. Fun wasn't it?
