to automate updating titleblock w/ viewport scale

Apologies looks like there was an extra line after the 'while' call. correct below:

 

# Define a function to list the names of all sheet layers in the current document
def list_sheet_layer_names(excluded_layer_names=None):
    """
    @type filter_layer_names: exclusive layer names list ie, only these layers to be returned
    """
    layer_names = []
    hLayer = vs.FLayer()

    # Use a while loop and the NextLayer() function to iterate through all the sheet layers in the document
    while hLayer != None:
        if vs.GetObjectVariableInt(hLayer, 154) == 2:
            layer_name = vs.GetLName(hLayer)
            if excluded_layer_names:
                if layer_name not in excluded_layer_names:
                    layer_names.append(layer_name)
            else:
                layer_names.append(layer_name)
        hLayer = vs.NextLayer(hLayer)

    return layer_names

 

Thanks a lot!! I realized what my problem is. I used vs.AlrtDialog(layer) at the end of this section to see what it returns and I realized it actually returns the sheet numbers rather than sheet titles. 

Since we have all the sheet titles fixed in our template file (sheet numbers will definitely change), I am trying to find a way to use the sheet titles in the code rather than the sheet numbers. Was trying to change the index numbers in the code to get the sheet titles but had no luck..

Ah I was able to revise it by adding this:

 

def exclude_titleblock(tblocks):
    excluded_blocks = []
    for tblock in tblocks:
        strRecordName = vs.GetRField(tblock, 'Title Block Sheet Data', 'Sheet Title')
        if strRecordName != 'Landscape Details':
            excluded_blocks.append(tblock)
    return excluded_blocks

                         
# Iterate through all sheet layers in the current document
for layer in list_sheet_layer_names():

    # Define criteria strings to find title blocks and viewports on the current layer
    titleblock_crit_str = f"(((L='{layer}') & (PON='Title Block Border')))"
    viewports_crit = f"(((L='{layer}') & (T=VIEWPORT)))"

    # Use the get_objects_from_criteria() function to get lists of title blocks and viewports on the current layer
    titleblocksss = get_objects_from_criteria(titleblock_crit_str)
    titleblocks = exclude_titleblock(titleblocksss)
    viewports = get_objects_from_criteria(viewports_crit)

 

Thanks a lot again for everyone's help!

And this, if there is a list of names:

 

def exclude_titleblock(tblocks):
    excluded_blocks = []
    exclude_names = ['Landscape Details', 'Landscape Sections', 'Landscape Cut Sheets']
    for tblock in tblocks:
        record_name = 'Title Block Sheet Data'  # Adjust the record name based on your specific title block record
        field_name = 'Sheet Title'  # Adjust the field name based on your specific title field
        strRecordName = vs.GetRField(tblock, record_name, field_name)
        is_excluded = any(name in strRecordName for name in exclude_names)
        if not is_excluded:
            excluded_blocks.append(tblock)
    return excluded_blocks

Thank you for posting that.  One suggestion for the future.  It is probably better to post code into a Code Block. It will wrap better and be easier for someone else to copy and paste.

 

I created this code block by:
	1. Clicking the <> icon in the editor tool bar.
	2. Writing this.
	3. Clicking the Insert into Post button
