Flood with cells?
I need to fill a cross section with cells. The purpose is to calculate the second moment of inertia, but that is not the issue right now. When I use the pattern/flood tool the area is properly filled with the cells – but, they have lost their status as cells and I cannot change to other cells which was idea for the calculation process later on. (The replacement cells would have lines to represent moment arms) Any other way to fill an area with cells?

To retain the cells as cells, you could use the Place Active Cell Matrix tool to create an array. However, this method will not trim cells to the edge of an area such as your cross section. You could use the fence clip tool to do the trimming, but then the cells would be dropped to individual elements. You can not trim or clip it and have it remain a cell.
Do they need to be cells?
1- place area with circles or squares, or cells, by array.
2- use place fence by element and make a selection set

Thanks for good hints that I have used in combination:
1 First a huge array cell placement covering the complicated section. (2000 cells)
2 Then a fence by element / copy and move out of the selection (with the inside option).
3 Replace the cells with cells having tails (lines) from the centroids downwards passing a base line.
4 Drop cell status to geometry.
5 Trim all lines to the base line.
6 Each cell 1x1mm2 has now left a line down to the base line that can be used to calculate the second moment of inertia.
Perfect!
The next problem is to read the length of every line and export everything to Excel.
How?
Grateful for further advice.

FlexiTable™ can do that. FlexiTable is a great tool for acquiring data from DGN models and other data sources. It's compatible with Microsoft Excel®

FlexiTable acquires linear, area and volumetric data from DGN elements. It saves element information in its worksheet. You can save a worksheet in Excel format.

BTW did you now that the measure tool can help with a lot of this is the element is a closed shape you have to turn on the mass properties tick and also the display centroid may be handy
