How to display point cloud in perspective mode in Microstation as it is in Pointools?

Hi All,

This issue made me crazy, you can see the point cloud displayed in the pictures below.

In Pic 1 there is the entire view of the point cloud data set which displayed in Microstation, I want to go inside of the buildings to see more details as in Pic 2 which displayed in Pointools, but when I tried to zoom in to find the details, the result in Microstation is displayed as the scene in Pic 3.

Wish someone here can help me out. I tried the perspective mode in MS, but not well.
