Simulate Pointcloud

Hi,
I have a absolute arm with the AS1 laser sensor, and would like to simulate a point cloud on the cad file so I can make the program offline ahead of the production of the actual part.
From what I can read in the manual, it seems that it would be possible to do this.
But I’ve tried and I can't get it to work, is there someone who has managed to do this and can describe the steps to get it working?
I’m using PC-Dmis 2023.1

Thanks,

Seems only available with the laser option?

You mean like a laser head in a regular CMM?
Perhaps, it doesn’t seem like I can get it to work with a manual arm.

Thanks,

For PC-DMIS Portable, the existing "Simulate point cloud" functionality allows you to read in a previously saved point cloud stripe-by-stripe, simulating the original measurement sequence. We have added the ability to simulate a COP from the CAD model to PC-DMIS 2023.2 which is currently scheduled to release around the middle of August. If you sign up for the tech preview, you will be able to download and give it a try.

Per Neil's post below, not yet, but in the upcoming 2023.2 it will be possible.

Hi,
Thanks, that’s good info.
Unfortunately, I can’t access the link you provided as it seems that I’m not authorized to view it.

Aha, that makes sense.
I’ll sign up and have a look.

I have the same setup, I write offline programs quite often without a pointcloud or simulated pointcloud.
First I open a new program, import cad, orient the CAD if needed. Then Insert Point Cloud Feature, then Insert point cloud alignment, and I figure out how I'll set up the part for a scan and determine points for the pointcloud aligntment. After that, create the features used to create the New alignment, then Insert New alignment.
Then just create everything i need for my inspection. I always play around with the detection envelope, and after I get an actual part to scan, the program will always need a little tweaking. But I am fairly confident in the programming offline.
