没弄懂上面的问题，那位老师给解释下？

应该指的是过一点引曲线的垂线问题，我想是不是这样：把引垂线与做切线分开，如果引垂线就限定只能选点与直线或平面。现有版本中引切线只能是点在曲线上，如果点在曲线外如过点(0，-2)在曲线y=x^2的垂线就即不是垂线也不是切线了。他要的应该是过点引曲线的所有切线，不过过点引曲线的切线系统是很难判断条数的。

Thanks!
And more I feel Tool of measurement is incompletion because I can't find volume of any solid and area of any polygon.
If you can, you should additional tool measurements for derivative and integral.
Thank you so much!

Idea about Page!
I feel tool of page of Inrm3D isn't as good as Geometer's skechpad.
Can you create an independent site not associated with each lool like GSP.
I think it'll be better.

Thanks! But I can't input character of maths.
In next ver, will Inrm3D hyperlink with mathtype?

Packer of InRm3d  solved file which has many pages very good. That's better if you have a plugin which insert inrm3d file into PowerPoin look like Cabri.

More suggestion
1- With control Calculate, You Should add a part to add or minus more value. Now it only animate one-way.
2- With control Move and Hide, You should make tool choose many object. Now it only choose one by one. Not good.
3- More, If you can, You should build control  Presentation look like GSP, It'll combined another control very good.
4- And text, I can't insert text of maths. I think InRm3D is a mathsoftware. What a pity if it can't show maths symbols.
5- About page, I can insert o delete page but can't swap positions between them.
These things I see.
Hope you make them in future.
Thanks.
