Project: HiCAD Point Cloud

Save / Manage Point Clouds

Point clouds imported into HiCAD have the geometry type Dummy and are marked with the symbol in the 3-D part structure of the ICN. When saving model drawings or parts with point clouds, it is important to note the following:

The point cloud data are not part of the SZA or KRA file. These files only contain a reference to the corresponding project point cloud, i.e. to the path where the point cloud is located during import. This reference can be changed later with the function Update point cloud references .

If you transfer files with point clouds to a third party, i.e. to another HiCAD workstation, then you must also pass on the folder with the project point cloud in addition to the SZA or KRA file. At the same time you have to make sure that this folder also exists on the "new workstation". The following exceptions apply:

• If the directory set as drive N in the filegrup.dat is part of the point cloud path, the point cloud will be found.
• If the directory set for drive N is moved, the point cloud is still found within this folder. However, this applies only if the point cloud has been added in a version from HiCAD 2020 SP1 onwards. This does not apply to already existing model drawings created with HiCAD 2020.

An example:

The directory C:\HiCAD\Point clouds is set as drive N. The point cloud file VHV Technikum.lsproj is located in the folder C:\HiCAD\Punktwolken\Examples\User\VHVTechnikum The model drawing with the point cloud is saved.

The model drawing is then opened on a computer on which the same directory is set for drive N. The point cloud file VHV Technikum.lsproj is located there in the folder C:\HiCAD\Punktwolken\VHVTechnikum.
-> The point cloud is found.

If HiCAD does not find a point cloud contained in a model drawing when loading it, the Update point cloud references dialogue window is automatically displayed. If you move the cursor over the symbol there, you will get more information.

After clicking on the magnifying glass symbol and selecting the desired path / file, close the dialogue window with OK.

The point cloud reference will be updated and the point cloud will be exchanged if necessary.

Example:

The model drawing contains for example the project point cloud VHV Technikum (1). This is located in the folder C:\hicad\Install\Punktwolken.

When passing it on to third parties, the entire folder (2) must be passed on, in addition to the model drawing with the point cloud. On the "new workstation" this folder must then also be located at C:\hicad\Install\punktwolken.

Please note:

• When you convert point clouds for import into HiCAD, they are by default stored in the folder defined as drive N in the file filegrup.dat. It is recommended to use a uniform drive N on all workstations. This can be a network path or a local path. The ISD default is the sub-folder Punktwolken of the HiCAD installation. Point clouds must not be stored in sub-folders of the folder Punktwolken!
• If the path specified in the file filegrup.dat as drive N is a central network path to which all workstations have access, then no forwarding of the folder Punktwolken is required. In this case the SZA or KRA file.
