Hi there.
Is there a way to increase Make2D accuracy? Often output lines are overlapping, or they are not touching.
What is the issue related to?
Yours Sincerely,
Max.

Hi Max, Make2D partially works off of an internal pixel grid to initially determine whether points along a curve are transitioning to visible or hidden. If the pixel grid is too coarse it can affect accuracy - there is a "Resolution" option in the Make2D command options that controls this density, try setting it to a higher value like possibly 30 (this generates a 30 megapixel internal depth map) and see if that helps. Setting it higher does consume a lot more memory though.

If that does not help could you send me an example file where you are getting overlapping or non-touching lines?

Michael thank you,
Basically in every project. Usually my make2ds act on a scene of around 200 solids with a bounding box of around 3000x3000 units.

Here's a simple example of overlapping lines.

Hi Max,

re: Here's a simple example of overlapping lines.

So unfortunately that's the expected result currently - dealing with curves occluding other curves along silhouettes is a generally difficult area to handle.

There is some silhouette curve duplication prevention in the hidden line engine but currently it's limited to cases where the curve is completely covered up by another curve - that catches cases like a box or extrusion viewed from the extrusion direction, but won't catch cases with staggered partially hidden curves like you have here.

Currently there is somewhat more of a focus in the engine on trying not to have missing areas rather than trying very hard to remove all overlapping duplicated areas like you have here.

Possibly it's something that can be improved in the future but it will likely take quite a bit of work.
