Question
Can I scale or change the height of all or selected the text in my drawing at once?
Answer
Select objects: (select all the text for scaling)
Enter a base point option for scaling [Existing/Left/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR] : (just press enter to keep existing insertion point for each selected text)
Specify new model height or [Paper height/Match object/Scale factor] : (choose the height required)"
