AutoCAD Sheet Set Manager properties shows '----' when you don't want to

Some users of SSM in AutoCAD don't want "----" or "--" (four or two hyphens/dashes) to show up on the plotted drawing when a property is empty.

Using a regular space character as a workaround to not getting "----" doesn't work for AutoCAD 2008 and older. It doesn't stay if the drawing is saved, closed and then opened.

In AutoCAD 2009 and newer if a space is added nothing will show at all, not even the gray area so that you could see that it is a field there. Nothing. That makes it tricky if the field is in a mtext object and nothing else as you will not see it and might delete it unintentionally. Also next time you go in and edit properties the regular space will be removed.

Here is a better tip for empty fields or blank fields.

What on the other hand stays is entering ALT-0160 (Non-break Space) on the keyboard followed by an enter. To do it hold down the ALT key and type the numbers 0 1 6 0 on the numeric keypad. Now the four dashes will not show up their ugly face. You can also enter \U+00A0 as another way but it did not work in all cases. If you don’t have a numeric keypad on your keyboard you can run Character Map (C:\Windows\System32\charmap.exe) and locate the No-Break Space or search for it. Then copy and paste it.

An alternative that also can work is to enter %% or %%U in the property value. It does not always work. If a field is added into mtext or multiline block attribute, or in a Sheet Set Table it fails but if a field in a regular block attribute it works.

Note that this may not work for all type of text font styles. If it does not work and for example shows a ? change the style to another like Arial.
