I am using IC 6.1.8 and I would like to have for figGroups the same "behavior" like mosaics : after I placed a figGroup I want to stretch it to create an array of same figGroup. It is much easier to work so and save a lot of time.
Mosaics are arrays of instances of cellViews; they have to have hierarchy. figGroups are a grouping within the same cellView. You'd have to convert the figGroup into a new cellView and then instantiate as an array/mosaic to be able to do this. You could use Make Cell to make the new cell, and then you can convert the resulting instance into a mosaic.
The issue here is not the power of SKILL; the issue is that there's no concept in the database for mosaics of figGroups. Unless it can be represented in the database, SKILL is not going to help you. You either have to convert it to a cell and then replace with a mosaic of instances (as I suggested above) or do an arrayed copy (which is then not a mosaic; it's a one-off copy which you can't then alter the array size/spacing). Both could be automated with SKILL, but I'm not convinced that writing SKILL code to do something you can do with two simple menu steps is worth the effort.
I thought now it were nice to have an arrays of figGroups that behaves like mosaics : in partial editing modus I can stretch with the mouse the array to fill the area with figGroups or if there are too many of them I can cut them with the mouse.
