SEMA has already set new standards in the processing of digital 3D data and its further processing in a CAD software with the import of 3D point clouds. SEMA raises the bar even further with the release of Version 20-2: If multiple point clouds are imported for a project, they can now be visually displayed in different ways.
The individual point clouds can be displayed or hidden separately from each other. The display of the individual point cloud can be controlled according to the requirements - the "point density", the "point size" and the "point cloud colour" can be adjusted individually.
This results in a wide range of applications for the stair builder. The storey-by-storey division of the 3D scan into several point clouds allows free access to the stairwell.
If, for example, only a certain section of the building is required in high detail, it can be displayed separately and the point cloud density can be set to maximum. A point cloud can be displayed with reduced density or completely hidden for areas that are less relevant. The flexibility when working with point clouds has, thus, been increased immensely.
A concrete staircase is to be fitted with treads. Consequently, the well-known function "Laser measurements stairs" is employed as the first step: Individual points of the concrete staircase are picked out for the stair ground plan within virtual reality. The point cloud of the storey above is hidden in order to make sure that all of the points required are captured. The concrete stair is then created with the covered construction desired. Manual changes can be made as usual.
The great advantage of point clouds is that a virtual reproduction of reality is provided in the program - there is no better basis. Multiple trips to the construction site due to forgotten or inaccurate dimensions are no longer necessary. Perfect construction site documentation.
