Poor Make2d results in Rhino8?

Hi all,

I get strange results when I use the Make2D.

First it’s based on a fairly complex model created in Rhino7.
And I also have to admit there are lots of net based step model downloads in the file.

Rhino 7 produces a hardly acceptable result using Make2D. Followed by several hours of fine tuning in case you want to avoid “poor quality” comments on your final drawing.

Now I tried Version 8 SR4 (8.4.24044.15001, 2024-02-13)

When I use clipping tools everything looks just like you have done a good job right from the start. Also the calculation time drops significantly. Congratulations to whomever :+1:

Is there a way to get colored results (keeping layers) using section tools?
If not I may ask for it right away?

But Make 2d turns out way different.

All lines are drawn invincible except for a few artifacts and 2 circles

which I can’t access for a move using a rectangle left to right.
Right to left works.
Most likely because the circles are accompanied by huge squares you realize when you do a zoom out.

Any idea what is going on here?
I used the same workflow like in Rhino7.

Are you able to post the file that you were using?

Sorry @Patt, unfortunately it is confidential and way to big for a forum post.

Hi Martin -

You can privately upload larger models from our upload page: Rhino - Upload to Support
I’m afraid we can’t really debug such issues from images.

Another approach would be to extract just a specific part of the model that illustrates the issue but doesn’t expose any of the confidential parts and post that or send it to McNeel. It’s a bit of extra work but might save time overall if you can get it solved.
