Current best practices - Reducing the amount of vertices on shapes

[christian_paulsen98V29]

Hello everyone, I wasn't sure if this would be best to put in this forum or the AutoLISP forum but this is where I ended up.

I'm sure we've all ran into scenarios where we have a shape (usually arcs or curves) that just has too many vertices. Sometimes times these arcs aren't really acts at all but instead are just hundreds or tiny straight lines all put together. I've recently been receiving files of shapes that were created in adobe illustrator and running into this issue a lot.

Which leads me to my question:

What are the current best practices everyone's been using to deal with these situations???

Personally I've used 3rd party programs such as signlab or some cnc softwares, but these can be expensive. I've also found some LISP files such as one called PLDiet (id credit the guy who created it but i don't remember his name) which seems to work good at reducing the amount of vertices but still does not give you a smooth edge. This LISP was created years ago though and is probably a bit outdated now. Then there's always the option of tracing or redrawing something but that can be time consuming and isn't always accurate.

Does anyone have any new lisps that work for this? Or maybe a AutoCAD extension, addon, or plugin? Any cheap and easy 3rd party softwares? I'm open to any and all ideas. My current process has been working but I'm sure someone out there smarter than me has an even better way or doing this.

You can follow this LINK and find out the guy that really can help.

try this also and experiment with inputs

it's really sad that AutoCAD doesn't have a command like this, but more enhanced, like to keep arcs and splines intact, just to remove excess vertices...

all current solutions transform every curved object to strait parts

[AVCPlugins]

The AVC ASimp plugin was created specifically to remove unnecessary vertices in polylines. It can also combine linear segments into an arc if the breaks are very small.
A more powerful program, AVC Outside Loop (OSP), searches for joined lines and arcs and builds polylines based on them.

Both programs support setting tolerances by which it can deviate from the original lines.

Autodesk does not change anything in the software if not enough people ask for it: do your part to ask/demand over here, and remember to encourage a few hundred other subscribers to do the same. Here is the link https://www.autodesk.com/company/contact-us/product-feedback
