Hi,


Please can someone advise how I can view my point cloud in better detail, when you zoom into the point cloud it look like It disappears (very Faint) I would like it to be rich in data

My Point cloud is an .rcp file

Once you have inserted the point cloud, right click it and select "edit attached data", then in the adjust density section, you can increase/decrease the Density gradient (how large the points appear), and the maximum allowed points.

 

That's all I am aware of to change the appearance inside Inventor.

I don't know about Inventor, but I do know about pointclouds.

 

If the original scan is lacking data density, then you can't do anything about it.

The point density is quite different between scanner types.

 

For example: If you scan w/a Lidar scanner (meant for landscapes), your point cloud will be much less dense than if you scan w/a handheld scanner (meant for complex surfaces). You can read about the specs on the various scanner web sites, such as Faro, Romer, Leica, etc.

 

Another example: A guy scanned a vehicle for me using a Lidar scanner. I needed to RE the body parts. But when I tried using that scan data to do the surfacing I found it was not dense enough to get any kind of reliable detail of the surfaces. The guy scanned the whole truck too, and it was a HUGE pointcloud, and it took him a number of hours to do it. But the pointcloud was totally unusable b/c it was just too low in resolution. The correct scanner to use would have been a handheld scanner, like the Creaform 700. I've seen guys use on vehicle bodies that with excellent results.

 

So if it was me, I'd find out what kind of scanner did the scan, and what resolution they used to do it. If it is too low, then maybe they can do it again at a higher resolution?

Hi! This may have something to do with the Point Cloud options. In the Attach command -> options -> make sure the options are set reasonably. Please note that Inventor part has a fixed modeling space (+-100m in each direction). When geometry exceeds the limit, the behaviors can become unpredictable. Please make sure the Point Cloud is bounded within the limit or not too far from the limit.

Many thanks!

Just my opinion

Yea, nah. Point clouds generally a waste of time. They look pretty until you actually need to use the data, then you realize that they are useless.

 

We use them on an ad hoc basis, mainly for site surveys and hi res point clouds of specific connection points etc.

I have to agree the resolution plays a huge role, the site surveys can only be viewed from a distance, and the hi res clouds still require a bit of guess and check.

 

When I client very proudly says that he will send a point cloud, I die inside as I know what a headache it is to work with them.
