View point cloud in 2D Wireframe AutoCAD 2016/2017

PatrickByrne — Sat, 18 Feb 2017 02:28:14 GMT

Hi I have just tried using pointclouds in 2017, previously I used them in AutoCAD 2014.

The pointcloud does not seem to be as useful in 2017. Is there a way to view the point cloud when the Visual Style is set to 2D Wireframe.

Thanks in advance

Hi,

>> Is there a way to view the point cloud when the Visual Style is set to 2D Wireframe

No, the hardware acceleration is needed to be performant enough for such high data-amount and I guess that is, why that makes a visual style necessary that can use the hardware acceleration, like "Wireframe" and all the other rendered types.

>> The pointcloud does not seem to be as useful in 2017

Can you describe why you see this now as not useful, maybe we can help on that?

I am coming from using Point Clouds in 2014 where it was possible to do these things.

The point cloud was visible in 2D Wireframe making it easy to line up your model with the point cloud.
I could select points using the node object snap
In 2017 when selecting the pointcloud I have to zoom out
In 2014 the bounding box section planes was easy to use

I am open to suggestions.

Regards

Patrick

Hi,

You can do the same in visual style "Wireframe".

>> I could select points using the node object snap

You can do the same now, and even more! You do have now a complete set of object snap help especially for point cloud:

>> In 2017 when selecting the pointcloud I have to zoom out

I can't see that issue, I can select the point-cloud at any zoom factor, do I do anything different to you?

In this video I try 3 different zoom factors and click to select, then zoomed out to see the border as selected item.

>> In 2014 the bounding box section planes was easy to use

Maybe I misunderstand "bounding box section planes". I use now the section planes plus the commands helping then to create new objects based on (virtual) edges in the point cloud, or creating automatic section lines ... not available in 2014 😉

There you find a video (not the best sample, I know) which shows how fast you can get geometry from a point-cloud. The resulting lines (e.g. from the walls) are the fastest option to built up your further redesign (imho).

Let's know if that news are useful for you or if your results differ to mine (in that case verify your AutoCAD 2017 is up-to-date/on Update 1.1).

I'm totally with Patrick. The "improvements" on 2017 make me want to go back to 2014 or even 2016. Come on Autodesk.

2D Wireframe is much faster than Wireframe.

Are there some settings for Wireframe that could be tweaked to make faster?

Hi,

>> 2D Wireframe is much faster than Wireframe.

For 2D yes, but not for 3D (and so not for 3D points clouds) as in visual styles other than "2D Wireframe" the GPU is doing the job much much faster (instead of the CPU/main processor).

If your system is generally slower in other visual styles (other than "2D Wireframe") then it's a question of graphic card and/or driver.

Video card is Nvidia Quadro K3100M.

NVIDIA Driver Release - Quadro Desktop/Quadro Notebook 354.56 Windows 10 64bit [10.18.13.5456]

I installed the latest driver from this link

This laptop has two video cards. One in the motherboard which is some Intel type and the Quadro. How do I know or tell AutoCAD to use the Quadro?

This is what AutoCAD sees. So I guess it is using the Quadro.

Some point clouds show in 2dwireframe. It looks like it may be a point cloud issue and when it was saved from Recap. I have some point clouds visible in AutoCAD 2016 and some not. They are all visible in regular wireframe. Maybe it is density?

Hi,

Am I correct that the pointclouds which are visible in 2D-Wireframe were already inserted in drawings created with older versions of AutoCAD? ... so no ReCap pointclouds?

The point clouds were created in previous version of recap and inserted into AutoCAD 14 within the last year. The point clouds were created with faro scans in recap. we have updated to recap non pro 4.2 and the new recap files I can't insert into AutoCAD 14. We do have 1 recap pro which seams like it can create files that open in 2014 acad. We have several non pro recaps also. Sorry if this is confusing.

That's the difference, AutoCAD 2014, and this old type of point-cloud referencing is just built in for compatibility reasons. But they are much slower on display compared to the current ones.

Thanks Alfred,
This is causing some issues in some 3rd party software, Bentley ProSteel has a slice command PS_OBJ_VIEW_CEN that is not working like before.
