真所谓温饱思淫欲，方老师就看你的了。也加一个cabri 3D类似的多面体展开功能。

Yes I see but I want InRm3D will be the best. It's both of cabri3d, Archimedes Geo 3D and itself.

I Believe We Can Do It

namtran

The future will be the best answer. We should comment to the manufacturer as better.

I think it will be better if InRm3d can be auto- rotate.
I always do it by hand. It's not good for me.

Has been achieved automatically rotated.

When does this tool active?Please! Thank!

This feature is not yet complete. Sorry.

About tool tangent in OXY!
I feel it isn't complete.
Example 1 : Tangent of graph of function y = x^3 - 3x^2 by the point A(3;0) are y = 0 and y = 9x-27 but with InRm3d only y = 9x-27.
Example 2 : tangent of graph of function y = x^2 by the point B(0;-1) are y = -2x - 1 and y = 2x - 1 but with InRm3d that is  y =-1(?!)
By the way, I feel it's true for tangent of graph of function at the point on this graph.
Please consider the general case!
Thanks!
