All polygons without material

Dear Stefanos,

Brilliant!

One command groupfiltered Polygons "Soil.Material=" completely solves my problem.
Maybe in some cases I need to add groupfiltered SoilPolygons "Soil.Material=".

Much obliged for your help, Stefanos.

And some commands to serve as an example for this case:

_gotostructures
_polygon (0 4) (0 2) (3 2) (3 4)
_polygon (4 5) (4 2) (6 2) (6 4)
_arrayr (Polygon_1 Polygon_2) 2 0 3
soilmat
tabulate Polygons "Soil Soil.Material"
_setmaterial (Soil_3) SoilMat_1
tabulate Polygons "Soil Soil.Material"
tabulate Polygons "Soil Soil.Material" "Soil.Material<>"
tabulate Polygons "Soil Soil.Material" "Soil.Material="
groupfiltered Polygons "Soil.Material="

Hello again,

Then, the powerful command tabulate comes in handy:

tabulate Group_1 "Parent"

Dear Stefanos,

Thank you very much for a quick reply.

echo Group_1[0].Parent is a good variant for one item.

But what can we do if we have more items in the Group?
For example, I have a project with three «empty» Soils:

If I use echo Group_1[0].Parent I will get only the first one (because of [0]):

Could you please inform me whether it is possible to get polygons number for all items in Group_1?

The only way I know is to copy all names from Group_1 (from right button click menu) and use echo:

Thank you in advance.

Dear Rushan,

You have correctly found that it is the Soils object that contains the Material property and not the Polygons. So, indeed the command should work correctly when using the Soils object.

In the Model explorer you should get a new group, e.g. Group_1 that contains that Soil object that means your criteria. If you click on the group or its contents the object should be highlighted in red and also shown in the Selection explorer.

If you want to know to which polygon this belongs, you can use the echo command in the following way:

echo Group_1[0].Parent # this will give the first item of the Group_1; this can also be called Groups[-1][0] using indexing
