Initialized SelectionSet

[gswifort]

Can I call Ed.Editor.select() with an initialized selection set to which the user can add or remove items?

@CEXT-Dan, any ideas?

Sorry im on vacation again, exploring Hong Kong. You may be able to create an empty selection set by creating a Ed.SelectionSet() class instance, then use add or remove. I'll be back on Monday

I'm referring to the following workflow:

1. The user selects a set of elements
2. The program processes the set and displays something based on the selected elements
3. The user decides whether to confirm the operation, add or remove elements from the set
4. The program displays the previously selected set (something like Ed.SelectionSet.ssSetFirst()) and the user can add or remove something from it
   Steps 2-4 repeat in a loop.

Enjoy your trip!

Still not 100% clear, still recovering from jet lag. maybe some of these will spawn some ideas?

from pyrx import Ap, Ax, Db, Ed, Ge, Rx
import traceback

def select():
    filter = [
            (Db.DxfCode.kDxfStart, "LINE"),
            (Db.DxfCode.kDxfLayerName, "0"),
        ]
    ps, ss = Ed.Editor.selectPrompt("(A)dd lines: ", "(R)emove lines: ",filter)
    return ss.objectIds()

def select_ctor():
    db = Db.curDb()
    ss = Ed.SelectionSet()
    for id in db.modelSpace():
        ss.add(id)
    ss.ssSetFirst()

@Ap.Command()
def doit():
    try:
        select()
        ps, ss = Ed.Editor.selectPrevious()
        print(ss.size())
    except Exception:
        print(traceback.format_exc())

@Ap.Command()
def doit2():
    try:
        select_ctor()
        print(len(Ed.Core.getCurrentSelectionSet()))
    except Exception:
        print(traceback.format_exc())

Also ActiveX has named SelectionSets, you can add a named set, then supposedly recall it at any time. I haven’t used these, I just noticed this with making the wrappers

[gswifort]

I mean something like this:

from pyrx import Ed

def doit():
    sset = Ed.SelectionSet()
    for id in obj_ids:
        sset.add(id)
        
    while True:
        sset.ssSetFirst()
        status, sset = Ed.Editor.select()
        # the user adds elements to or removes them from the initialized set
        if status == Ed.PromptStatus.eOk:
            process_sset(sset)
        else:
            break
