DSTV Contour Marking Limitations

Hi,

I am in the process of experimenting with ProSteel's ability to add contour marking (for cleat/stiffener/etc) locations in the shape's DSTV .NC files.

I have found a few limitations and am looking for other user's feedback & experience on this topic.

So far I have found:

1.  For channel members (PFC) contour marking can only be displayed for items located/welded to the back of the channel web or onto the outside flanges.  Any items welding to the inside of the channel web, will not have contour marking displayed.

2.  For channel members (PFC) contour marking, for items welded to the back of the channel web, will also be displayed on the inside of the channel web.

3.  Contour marking cannot differentiate between different groups/assemblies.  For example, you could have 2x groups (B1001 & B1002) both with the same fitting for the main part (f1001).  Let's say that B1001 has stiffener's welded to it, and B1002 is a single shaft.  The .NC file contour marking for f1001 will only show the state of 1 of the assemblies.  It could possibly represent B1001 or B1002.  Hard to explain, sorry.

4.  Contour marking cannot be shown for inside unequal angle shapes.


Has anyone else found any other limitations to the DSTV contour marking?

I need to explain all of this to the fabricator.

Thanks for any help.
