Hi All, Can anyone explain how to create a revolve surface in an assembly for the purpose of measuring a flow area through a specific area? See the attached JPG, I basically have a conical internal diameter with a pin protruding into it..... I need to measure the flow area as shown in the sketch attached here. Please let me know if anyone can be of any help. FYI....... the way I have this shown in the attached JPG is the way that we had previously performed this in Pro-e. Thanks in advance! Doug
Solved! Go to Solution.
I can't tell anything from the image posted, but -
you could create a new part and in the context of the assembly Copy Object to get surfaces to aquire the information you need.
Attach the assembly here if you can't figure it out.
Create a new part in the context of the assembly.
Project Geometry the reference lines/points from the assembly parts.
Sketch the line you show.
Attach your assembly (or simplified representation) here if you can't figure it out.
I'm not sure if this will help, but there is an option in the Loft tool called Area Loft that might work. It will allow you to determine or speciffy the area of the loft section.
For instance, here the red arrow indicates a section that is specified in the loft to be 800mm^2, the area of the sketched sectons are reported also:
Just something to try maybe.
I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Or you could use a bit of math:
Area of a frustum of a cone:
A = π s (R + r)
Where: s = length of side (Not height)
R = radius of bottom circle
r = radius of top circle
Ya, I've already done it the old school way, thanks! ..... I guess I'm simply spoiled after a decade + of simply sketching a line and revolving it as surface in Pro-e. The nice thing about these surfaces is that you could leave it surpressed in your assembly and it'll update as you modifiy your assembly thus allowing you to check your surface area through that specific area at any time (without having to go through the math everytime).

You can do exactly the same thing in Inventor. Trivial 1 minute exercise when you know how.
Post example assembly here (make something up).
JDMather and all who replied.... Thank you! The difference is that in Inventor we need to create a "part" to revolve a sketched line as a surface. In Pro this was simply an assembly feature... no additional part file was required. Thanks again! Doug
Actually there was no need to create an additional part - you could have done it in any of the existing relevant parts in the assembly.
I just suggested another part as some post here with confusion about solids and surfaces and also it might be a better technique for housekeeping of files.
