dynamic updates

AFAIK, dynamic updates in a "Select modifier" is not currently possible by using maxscript. There is too much limitations. Maybe possible if someone find a workaround to all this limitations...

IMO, what you would like needs to be hardcoded in c++.
Notice that a "dynamic plugin" means also a "slower plugin" because
it will often invalidate and recompute the cache in memory.
Best regards.

thanks for the hint!

thanks for the hint! this is exactly what i need, but as modifier, which will work in modifier stack (dynamically updates). for example between Volume Select which get polydon selection and convert polygons to edges.

Poly_Select modifier

Hi, There is already a plugin but it is not a "one-click" solution.
1-Apply the Poly_Select modifier
2-Enter in Edge subobject level
3-Click on button "Get Poly Selection".
As you see, there is only 3 steps but if need to do it very often you can make a shortcut with a script like this : 

 
if classof $ == editable_poly do 
( 
 $.ConvertSelection #Face #Edge 
 addmodifier $ (poly_select()) 
 subobjectlevel = 2 
)

Drag and drop the code on a custom toolbar and a new button is created.
Of course, you can modify the script to make other conversions.
Source and destination tags can be :
#Object|#Vertex|#Edge|#Border|#Face|#Element|#CurrentLevel

I borrowed a paragraph from

I borrowed a paragraph from subobjects_converter.ms to use
Very convenient when I use PolyShiftUseSelectedToggle

	case  subobjectlevel of 
	(
	2: try i.baseObject.ConvertSelection #Edge #Vertex 		catch (modPanel.getCurrentObject()).ConvertSelection #Edge #Vertex
	3: try i.baseObject.ConvertSelection #Border #Vertex 	catch (modPanel.getCurrentObject()).ConvertSelection #Border #Vertex
	4: try i.baseObject.ConvertSelection #Face #Vertex 		catch (modPanel.getCurrentObject()).ConvertSelection #Face #Vertex
	5: try i.baseObject.ConvertSelection #Element #Vertex 	catch (modPanel.getCurrentObject()).ConvertSelection #Element #Vertex
	)
