Dropdown fields for variable block attributes

[Anonymous]

Hi guys,

Is there a way to create a drop down list for variable attributes? The blocks I have in my drawing have multiple variable attributes – for example ‘height adjustable’ attribute for ‘chair' blocks - where in the value field one would enter ‘Yes’ or ‘No’. I was wondering if there is a way to have a dropdown list in the value field for the variable attributes? So, when you insert a block, rather than a person manually typing in the values for the multiple variable attributes (when sometimes spelling mistakes can occur), there is a drop down list of predefined answers to choose from.  

Please note, some of the prompts for variable attributes are more complex than 'yes' 'no' answers, hence why I want to eliminate spelling mistakes by having a dropdown list to choose from for multi-users.

Someone has mentioned visibility states - but not sure how this would work with block attributes? Bearing in mind I will be extracting the attribute data in a table format using a Extract Data tool.

If you could direct me to any info for this, it would be much appreciated!

Yes, you can add that functionality.  The method I would recommend would be to add a lookup for each attribute you want selectable in predefined states.  Add the various lookup properties and add a field to each attribute, displaying its lookup property.

Look into using Lookup parameter and/or a Block Table.  Options vary with each.

The lookup method uses a field as the attribute's value to access the lookupstring value. You can have multiple lookups and you can have more than one attribute us the same lookup value.

The block table method supplies the values to the attributes by including the attribute in the table. You only get one of these tables per block. The table can supply unique values to more than one attribute at a time. The selection menu/list for a block table can branch to subselections in order to get to a unique selection.

Here's a screencast showing the lookup version.  As mentioned block properties will work also and will avoid the regen, but the selection process with the nested dropdown menus in this case would be a real turnoff for me.

M2P is "midpoint of two points."  It works when you are in another command and the host command asks for you to enter a point.  If you enter the command M2P, it will then prompt you to enter the 'first point of mid' and 'second point of mid'.  Once you have selected those two points, the original command will resume as though your original point selection was the mid of the two points.  Here's a screencast to show it working:
