Surface profile between sections on a curved surface

[[Ki...]]

Hi, 

I have been tasked with measuring a surface profile on a coned part. The patch I can select includes more surface than needed. I have attempted to use the deselection in 3D tools with no luck. 

The surface area is essentially where the black point is. The image shown is a section through the cone. The surface profile is on a quarter of the cone AND between two other sections. 

 

Any ideas on how to approach this? 
Thanks

Hi Kieran

I also encounter the exact same problem, where the nominal over-selection cannot be edited.

You can still control the result by editing the selection area of the actual element.

All this when it loses its consistency with the nominal element and then you will see that in the "Based on" row it has disappeared.

You can control the actual element using the deselect tool on surface or the decrease selection area tool by its two available options.

Another solution I found, although it is not possible in every case, is that I asked the product engineers to split the CAD patches for me exactly according to my need and so I could immediately get both nominal and actual the element as I need it for the program.

Tell me if this helps you.

Hi Yizchak, 

 

That does indeed help, thank you. 

I think we will try and ask them to split the CAD patches and if not focus on the actual element and try and get that as repeatable as we can.

Thank you
