Welcome to the world of MicroStation Python! In this wiki, we will explore how to Search for texts in elements and add to a Selection Set.

Search Text and add to a Selection Set

To get started, refer to the Python Manager wiki for instructions on creating and loading a new Python project. Name your project "SearchText.py" and save it in a convenient location. Once created, open the project in your preferred code editor to begin writing your Python script.

Here is the complete script.

from MSPyBentley import *
from MSPyBentleyGeom import *
from MSPyECObjects import *
from MSPyDgnPlatform import *
from MSPyDgnView import *
from MSPyMstnPlatform import *


# select_texts function
def select_texts():
    # Entry point to select text elements

    MessageCenter.StatusCommand = "Select text elements"
    MessageCenter.StatusPrompt = "Runs automatically..."

    active_model = ISessionMgr.GetActiveDgnModel()
    elements = active_model.GetGraphicElements()

    for element in elements:
        eh = ElementHandle(element)
        if is_free_standing_text(eh):
            check_text_contains_string(eh)


# is_free_standing_text function
def is_free_standing_text(eh: ElementHandle) -> bool:
    # Element should be both TextHandler and simple Text Element
    return isinstance(eh.GetHandler(), TextHandlerBase) and 
                      eh.GetITextQuery().IsTextElement(eh)


# check_text_contains_string function
def check_text_contains_string(eh: TextHandlerBase):
    # Add text element to Selection Set

    text_query = eh.GetITextQuery()
    text_part_ids = TextPartIdVector()
    text_query.GetTextPartIds(eh, ITextQueryOptions(), text_part_ids)
    first_text_part = text_part_ids[0]

    text_block = text_query.GetTextPart(eh, first_text_part)
    result = text_block.FindText("Line", TextBlock.FindTextParameters(), 
                                 text_block.CreateStartCaret(), 
                                 text_block.CreateEndCaret())

    if (result is not None):
        SelectionSetManager.GetManager().AddElement(eh.ElementRef, eh.ModelRef)


# Main function
def main():
    select_texts()


# Main
if __name__ == "__main__":
    main()

Run/Execute project

Load the project “SearchText.py” from the Python Manager dialog and Run/Execute the python script.

In the following example we are finding elements containing the word “Line” and add them to a Selection Set.

Happy coding!
