Parametric cells with lines on different levels - why do they behave different than normal cells?

Hello everyone,

we want to use a parametric cell-library for 2D-drawings of certain standard parts e.g. flanges.

Afterwards we want to use these in different drawings.

All our lines in the 2D-files are laying on different layers and have colour, line weight, line style (dashed, point dash, etc.) set to “by layer”. And later on the plotter configuration uses these styles to print the lines correctly.

Now here is the problem we run into at the moment:

 

If we create a flange and we have the main lines sitting on one layer and the lines for the bolts on a second layer, all these are lost when we place the cell in a new file. That is because the whole cell gets dropped to one layer only.

Here is the comparison: left side how it looks while creating it in the cell library, right side how it looks when the parametric cell gets placed.

                                           

Note: I just changed one of the dashed (red) lines to give you these example pictures. We already found the workaround to create the look of the dashed lines using explicit values for color and so on, and not have them “by layer” anymore. But it would be a great feature to get the look “by layer” back as it is with normal cells.

Is it possible to change this behaviour to the same as normal cells do it: Everything that lays on default in the library gets pushed to the level you place the cell on but the rest remains its original layers? 

If not, does somebody have the same problem? Is it worthy to put up a change request?
