Topic: Dynamic Block Predefined Legends

[MSTG007]

This is just a out of the park question (again).

I am curious if there is a way to create a dynamic block that will show options of what the block should show.

If I have a Proposed Legend, and it has the following:
Proposed Legend
1 - New Pavement
2 - New Curb
3 - New Ramp
4 - New Paint
5 - New Bollard

and I would just want to choose maybe 3 of the options,

Proposed Legend
1 - New Pavement
3 - New Ramp
5 - New Bollard

(And they would autostack?)

Again this is just a guess if its possible... Just trying to brainstorm some ideas around.

Thanks guys.

Visibility states....and or allow the column to collapse to 0 and the text to shrink proportionately somehow using a formula linked to the length of
some line on a no plot layer to determine text size

IME, legends are usually a library of symbols that could be used and do not necessarily mean that every symbol is used. The approach you are talking about is too much work for symbols.

What you are describing "could" be something like a BOM which can be created with data extraction. The resulting table could possibly have symbology associated with the line items. I'm just thinking out loud. I have not done this in AutoCAD but I think it is possible.

Well, Lets say there is no need for block symbols, just a simple MTEXT.

And I am trying to visualize how to build what Michael said.

That should be simple with a table. I'll defer the methodology to someone more knowledgeable, though.

The sad part is; within Land Desktop which Civil 3d was supposed to be an improvement to,
there was a tool to create a Symbol Legend.
It would scan the file for all blocks and assemble them into a table without borders, and list the block name.
If one had good block naming convention the table was near perfect every time.

this scales...one could chain a stretch action to close the gaps created by scaling unused entities

An alternate

Add the layers in question to a Layer Filter

Customize Layer Dialog to show Layer Name or Description ONLY

Select those layers in the filter

Ctrl+c  (copy)

In drawing Area Ctrl+V (Paste)  You get your layer list

12-1207|ACREAGE_TXT   white   LineWeight025    12-1207|ADJ-LINES   33   LineWeight020    12-1207|ADJ-TXT   53   LineWeight013    12-1207|ALTA   white   LineWeight015    12-1207|AREATXT   white   ByLineWeightDefault    12-1207|ASPHALT   8   LineWeight013    12-1207|BLDG   blue   LineWeight025    12-1207|BLDG HATCH   254   LineWeight000    12-1207|BLDG-PORCHES   152   LineWeight013

Direct... I like the idea. Thanks man.

One could even use the Data Extraction Route...if the Filter Method is to complex.

Select the objects one wants in the LEGEND  extract their layer names.
