Some users may experience slow loading when initially entering 3D View. It is generally due to the large amount of data being displayed at the same time.
After verifying your computer specifications and internet connection (see Cintoo Solution Specifications), here are the tips to overcome this kind of issue:
1) Organize your data
Scans:
If the project contains hundreds or thousands of scans, organize the data by work zones and not have all scans in the root or one unique work zone. Place the scans in sub-work zones, for example by Floors, by Areas, etc. (see Organizing Scans into Work Zones)
3D Models:
If the project contains one or several 3D Models containing thousands of objects,
create sub-work zones under a 3D Model work zone organized by Disciplines or by Floor/Elevation, etc. Placing one model per work zone will provide a lot of flexibility in viewing models.
2) Navigate in 3D
A) Never switch directly to 3D view from the root of the project (Active Work Zone)
This will display all project files in 3D view in 3D Navi mode, so it will start by loading all the models first (thousands of 3D objects) and then all the scans (hundreds or thousands) one by one, CPU and internet bandwidth are overloaded.
B) Recommended way to enter in 3D View:
1. First in the Project Explorer, select only one needed scan work zone in 3D View
2. Go to Overview Map
3. Select X-Ray mode in the Display Settings
4. Click on the Scan position needed in 3D View
The 3D view opens in Scan Mode at the scan position chosen:
Navigate from scan to scan or in 3D Navi mode. Add the 3D Models need to be displayed with the scans by ticking the corresponding work zone (one by one) in the Work Zone Explorer:
Add another scan work zone (Floor/area) if needed by ticking the work zone to add it to the 3D View:
Reduce the number of 3D objects from the model if needed using the Model Content Explorer, to hide temporary parts of the 3D model which are not relevant with the View (see this article: Model Content Explorer).
Finally, if loading is still slow (especially if hundreds of scans are displayed), temporarily switch off the Navigation Map on the bottom right corner by clicking on the Navigation Map icon:
In fact, if there are no Site Map or Model Lines (e.g. 2D DWG), the default setting of the Navigation Map is Scan Colors mode. So when first opened a scan work zone in 3D View, it will construct the Navigation Map from all scans, which uses CPU and internet bandwidth.
Switch off the Navigation Map temporarily, and re-open it to finish loading the Navigation Map when the 3D View is loaded and smooth. If a Site Map or Model Lines are present, switch to those modes instead of Scan Colors mode, since they do not use as much CPU or internet bandwidth.
