Polyline Pro

Polyline Pro is an easy to use yet powerful and intuitive tool which provides a clear and efficient user interface to create splines precisely with measurements and angles in a manner similar to AutoCAD. The main purpose of Polyline Pro is to bring the spline drawing in 3dsMax at a higher level.  

With Polyline Pro you can:
    • draw splines in Orthographic, Polar, Arc and Freehand mode
    • create points using Absolute or Relative coordinates
    • use direct distance entry - point in desired direction and type the length and/or the angle to create a segment
    • edit splines 
    • use guides and tooltips
    • use short commands for quick access to almost all of the features
    • use Object Snaps to mark certain points/lines and continue to draw in their projection or intersection
    • draw spline using World Coordinate System or User Coordiante System

  1. It's extremely useful and I recommend it to all who use Max. One small problem is that it occasionally becomes very unresponsive and locks my computer up. I'm using Max 2016. Other than that, I love it.

    1. Hi!
      I'm glad that you like Polyline Pro.
      Can you send me a mail with more iformation about the problem you have?

  2. Totally recommend this script. Using it on max 2016 since yesterday without issues. Only issue I had was after installing I don´t get any message the install was successful or not. But I know it was installed cause I have been using it and it works great with max 2016. Thx

  3. Dude, your scripts are great time savers,
    I like them so much that I just bought 3 Scripts from you.... looking forward to put them to good use.
    Nice work.

  4. Thank you for this piece of brilliant tool, It is very useful when you work precisely in 3DS Max. It works flawlessly in 3DS Max 2015.

  8. hi Kostadin Kotev,
    I am trying to install your polylinePro script you sent me on my email to 3dsmax2017 but I get unsupported 3dsmax version error. The file name is miauuPolylinePro_v_1_4.mzp. Do you have any updated installer for 3dsmax2017? I cant install the updates directly it needs the original installer first.

    1. Hi!

      Version 1.6 have to be used with 3dsMax 2017. If you want to have a full installer, please send me a mail to miau_u@yahoo.com.

  9. Hi~
    Can you write a script like "Bpoly" in AutoCAD ?
    That's the only reason I make 3d model in AutoCAD

    1. Do you mean BPOLY-Region method? Where the selected closed spline is converted to a polygon filled with quads?

    2. select shapes > click inside the shapes > Find the boundry > and create a new bpoly for extrude. So, I don't have to trace imported cad file again, (I hope you know What I mean.)
