will any body help to draw the following model in 3d

autocad 2012

especially the rib

thank you in advance

Are you familiar with the REGION command?

[ReMark]

I used the Region, PressPull, Subtract, Union and Slice commands. Not necessarily in that order to create this rough version of the object shown in your PFD. There are probably several other ways it could have been done.

[safadif]

thank you

will you explain more

i've tried wedge to draw rib but it does not work

it does not reach the circle

[ReMark]

I drew the "rib" as a triangle then extruded it. I used an extruded arc to trim it back (SLICE command) so it matched the curvature.

Post what you have done so far.

[ReMark]

How's it going there safadif? Done yet? Where's that image?

 

Hmmmm.....no response. Guess he figured it out on his own.

thank you all

i've tried that but i do not know how to slice it with arc

[ReMark]

Extrude the arc. It becomes a surface. Use the Surface option of the SLICE command to trim back the front edge of the rib.

When in doubt - attach the dwg file here.

You will get more detailed help.

Maybe this image will help. I used a rectangular box instead of a triangular rib so you could see the result better.

 

Both the rectangle and the arc are extruded. The box is a solid while the arc is a surface. I invoke the SLICE command and pick the object to slice. Then I use the SURFACE option and pick the extruded arc. I accept the option to retain both pieces of geometry (you don't necessarily have to do this) so each could be seen in this demonstration. Finally, I erase the geometry I don't need along with the extruded arc.

 

Does this help at all?

 

Here is what the inputs look like after invoking the SLICE command.

 

Command: slice

 

Select objects to slice: 1 found (the rectangle is picked)

 

Select objects to slice:

 

Specify start point of slicing plane or [planar

Object/Surface/Zaxis/View/XY/YZ/ZX/3points] : s (the Surface option)

 

Select a surface: (the extruded arc is picked)

Select sliced object to keep or [keep Both sides] : (default is accepted)

 

Any further questions?

safadif: Did you finish your drawing? Can you post an image?

[GAcadman]

seems simple enough, I wonder if the Original Poster every finished his model

[JD Mather]

The assignment was probably due 30 minutes after original post (or more likely - the day before).
