Here is a free measuring stick. You can use it to get accurate heights while in Elevation or Section views. Add the jpg of the dim style you need (imperial or metric) then use the following instructions to apply the image to a resized 'column'. You can move the column where you like in the plan and read the heights in Elevation / Section views.
Allan, it would be nice if you could post the example you made of the measuring stick in use.
Here are instructions on how to apply the jpg Ruler image to a column. (added new instructions that were deleted in forum update)
Download Scale Image of Choice
Download one or all of images of 'Rulers' to a folder on your computer that will not be moved. (I have folder called 'Materials' w/ subfolders)
Create New Column
First select Column tool and the right click in Catalog> Add New and size column to 9'x 3.5" (varies based on scale of image).
Switch to 3D mode and place the new column in drawing.
Materials (images) in Catalog
Add the new 'Ruler image' to your catalog.
While in 3D, select Paint Brush tool. When materials are showing ,in GROUPS, right click and select Add Group (mine is 'JK MATERIALS')
Move cursor down to "MATERIALS' below GROUPS and right click 'Add New', locate and name the new Ruler image material you saved.
Assign Image to Column
Select the Column, right click.Properties. Go to Materials 'tab' and under Materials list >click Select and navagate to the Ruler image saved to Catalog.
This assigns the column the texture of the Ruler image.
Mapping Ruler sizeNow go to the Mapping option, select Override Tile size and resize the material to fit the column (9' x 3.5") etc.
Don't forget to give the Column itself a new name (9' Measuring Stick). If you don't do that at first in Catalog, you can go to File > Catalog>Save Element to Catalog and then click on the newly named Measure Stick which will add it to the catalog for you.
