decorative fixture base.

So. im modeling the base to this fixture and i cant get it to model the way it needs to look. I have pretty goo experience modeling stuff. But ive never come cross something like this. my issues is i dont know how to model the leafs that curve upwards. as shown in teh front view detail.

What program are you trying to model that in?

Your image shows AutoCAD, not Inventor?

If you are attempting that in Inventor - attach your ipt file of what you have completed so far.

[llamas91]

I apologize. i recived the dwg file in autocad and it is my job to model it in inventor. The AutoCAD images was just to show what i was trying to model.
also. something to note. the way the file is right now. its partially revolved symmetrically at 22.5 degrees since i will then array the features 16 times.
 

lastly here is the part, its in Inventor 2013. 

[JDMather]

Sketch16 is missing dimensions and geometry constraints (Tangent, Horizontal, Vertical)....

Work Axis1 is a duplication of the Y Axis and therfore not needed.

I recommend you start here

then

Now you are ready to tackle this complex geometry (Loft will be your friend).

[JDMather]

hmmm, after experimenting a bit the geometry might not be as complex as I initially thought.

It appears to be a series of revolutions.  It would be nice to know where the axis of revolutions are.

It is a bit tricky as each portion needs to be solved separately.

This will still be a challenging part without more information.

[llamas91]

What kind of more info do you need? 

[JDMather]

from your dwg file it appears that the information I need doesn't exist (unless there are some hidden layers you have turned off).

Without the axis of revolution for the features it will all be a guess to make the part look similar.

[llamas91]

well ive been using teh C.L. as teh axis of revolution for the features.  Im not sure of what other axis there might be. All the layers are on. would the actual DWG file help?

In AutoCAD click on the arc shown in attached.
Where does it show the centerpoint of the arc?

This will be a challenging part for a beginner.

I won't have time to show you how to solve the problem.

The dwg file will be needed, and I suspect from what I can see that even that will not be enough - it looks like there is information missing.  Would probably need an actual part to reverse engineer.

I think the key to modeling this thing is to figure out how the original was made (assuming the mold/model was made from a assembly of machined components and not entirely hand carved).

[llamas91]

Well we acnt reverse engineer it. cause this is a brand new design. so their is no mold not even an existing cast part. all i have is the dwg file.

I attached the file regardless of the situtation.

Ah, so you don't have to exactly reproduce some historical detail.
I'm back to Loft as the way to the solution.
