add more blank space when using \starteffect[hidden]
Hi, Sometimes, I need to hide the solution of a problem. So I use \doifmode{} and \starteffect[hidden] as in the following sample file. Since I want to set more blank space if it is hidden, I add \blank[5cm] when it is in the \enablemode[hideSolution]. It works well except the figures and bars are not hidden. Only texts, even in the mp part, are hidden. It is OK for me. However, it would be much better to set the height of blank space depends on the height of hidden texts. Is there a way to set the variable height using “overlay” stuff instead of \blank[5cm]? Thank for reading.

Dear Hans, Thank you for your answer.
\framedtext[empty=yes]
Yes, it clears everything in the frame. But the frame is also clean when I disable \hideSolution. In that case, texts should be appeared. What I want is the following: If \hideSolution then hide text and add more blank spaces else show full text and no more space. endif The full text for the students another for the lecture. Is there a way not using \framedtext? Thank you again. Best regards, Dalyoung
Dear Hans, I found a command \determinenoflines by googling. I made a MWE as following. It is working well. But I have to write the paragraph twice for couning. Is there a better way?

Dear Hans, It is very interesting example. Thank you for a new method. Best regards, Dalyoung
