How to get the real text height from the selection?

[wuhuan2080]

Layer 0 is HZ fonttype，

Text selected from selection is romans ，the real height is 3，but when i use the Methods as follows:

Height = objText.Height

or Height = TextHeight(objString)

The value of Height are not 3，but is 510，so weird？（AutoCAD 2004， cannot use GetTextHeight（））

 

The code as below for reference：

can you post the entire code? Also my guess would be that this needs to be converted from some format. I did try to test your example but either my version of .net or Autocad gave me issues.

That kind of sounds like a drawing units issue, if so you can convert, or set a known unit for realible data;property extraction.
