[3ds Max Script] miauu's Scalpel

miauu

miauu's Scalpel allows you to interactively subdivide (cut up) geometry by drawing lines.

When you make a cut, it has to originate from a vertex or an edge. You can't create vertices inside faces.

With miauu's Scalpel you can:

• Snap the cut point to the nearest(to the mouse cursor) vertex (Auto and Manual mode provided).
• Snap the cut point to the center(midpoint) of the nearest edge(Auto and Manual mode provided).
• Snap the cut point along edge's length to set a precise cut location(in percentages of edge's length). The smallest percentage that can be set is 0.5%.
• Snap the cut point along edge's length to set a precise cut location(using the system units). The smallest value that can be set is 0.01 units.

• Make perpendicular cut from vertex to edge or from one edge to another using two different options:
  • the cut line is perpendicular to the snapped edge
  • the cut line is perpendicular to the edges from which the cut starts

• Use the default QuickSlice with snapping to predefined angles.
• Use a small heads up display of data related to the current cut point as a position along the edge as a percentage, the two distance values indicating the distance to either point in the cut edge, and the total length of the edge.
• See the options for the tool in the Prompt line.
• Change the values of the Snap Step and the Snap Angle while you cut.

Known Issues:

• The mouse cursor must be over the object you cut when you click with the mouse buttons. Otherwise the clicks will not be detected.
• While you are performing a cut the Snap Step can be changed only using the spinner's arrows.

Works with Editable Poly objects and Edit Poly modifier.

Cool stuff! very similar to multi cut in maya

Noors

Does it fix the half assed default cut tool behavior, which has been creating, AFAIR, stupid edges basically everywhere but where you mean to ?

I would also like to know this, I'd buy this if it just fixed that one issue where it makes random verts in between each edge you cut in. Which somehow is still a problem in Max 2020.

@Noors, @zachagreg can you show me an example of this problem? A sample scene, video, steps how to get the same results with the default cut tool?

@demigodss, thank you.

Noors

Create a cube, delete one face, flip normals, backface cull.

Try to cut the opposite face.

I have tried this tool and yes it fix the max default cut tool. So there is no half splited edges or unprecision resulting in vertices I’m the middle of nowhere.

I approve that tool ! It should replace totally the default cut tool or default paint connect tool.

miauu

I will make a video to show you what happens.

Edit:

The video is here:

As far as I can see the cut lines depends of how the objects i spositioned.

Quick update. Please watch this video:

If someone wants I can upload the scene so you can check it.

In the update next week - perpendicular cut from vertex to edge.

That is genius !

You mean the next update?

Thank you.

Both, the quick update for backface fix, the next update and the reactivity

Thank you.

Quick comparison of default Cut tool and miauu's Scalpel using the Box with flipped polygons and Backface Cull ON, as Noors suggested.

miauu’s Scalpel version 1.5 is available.

Changelog:

• New Perpendicular cut - the cut line is perpendicular to the edges from which the cut starts. To activate it, hold down the Ctrl and Shift key. In the prompt line this Perpendicular cut is named “Shift + Alt - Perpendicular cut EE”. If perpendicular cut is possible, you will see an icon over the vertex from which the cut starts. This icon shows where the 90° angle is located.

• To activate the QuickSlice you have to press the Q key on your keyboard.
