Hi, I received 3D scans of boats and basically, I am tracing curves over the point cloud. It works well, but for some reason, every line that I draw in Rhino ends up showing very thick, especially when I zoom or move around my model, parts of the line appears big and other parts as a normal line thickness and it changes as I zoom or move. When I hide my ‘‘curves’’ layer, the background becomes fine again. If I change the color of the layer or lines, the background become that color. Can anyone help me figure out how can I have normal line thickness? My lines are setted to ‘‘hairline’’, so as small as possible. I did the reset command too, nothing changes. Rhino Tech Supports opened the files that I emailed them and it opens fine on their side. It does that on any file that I open. I use Rhino 8. Thanks!
Hi François,
Do you open a new Rhino file and import the point cloud data or open the point cloud file and trace in that?
Regards
Jeremy
Hi Jeremy, I received those 3D scans files from a company so I downloaded the files in my PC. I just clicked on the downloade file to open it. I am tracing on the point cloud received the company.
Thanks,
François
Hi François -
What happens when you don’t open a file that is provided to you but just launch Rhino and create a line?
In a file when you see this behavior, please run the Rhino SystemInfo command and copy-paste its output here.

Hi Wim, I just tried drawing lines in a new files and seems somehow fine, even if when I’m drawing, lines sometimes appears thick for a mili second. Maybe beacuse the file is really smaller than my point cloud.

Hi François,
Your laptop’s graphics fall below the minimum recommended standard for Rhino. Apart from rendering though that may not be a show stopper. However, your video drivers are really ancient. Update them to the latest you can find for your machine. That could be a significant change.
Whilst your laptop’s memory meets the minimum standard for Rhino, I’d think about upgrading to significantly more if the video driver update doesn’t cure your problems.
