New Vertex

Create Vertex

Found on the Geometry menu under Vertex > Create, the Create New Vertex dialog lets you create vertices one at a time by specifying their location in 3D space.

To create an individual vertex do the following:

1) On the Viewport Shading popup choose Visibility Options > Show Vertices.
2) On the Geometry menu choose Vertex > Create.
3) On the Create New Vertex floater, specify the X, Y and Z coordinates for the vertex location.
4) Click OK.

The vertex is visible in the 3D model View.


Set Position

Set Position

The 'Set Position' command lets users reposition an existing vertex (or many) to a specific position using numeric input, this option makes it easy to for instance center an entire loop of vertices on the zero position for a mirror operation. Set Position can be accessed from the 'Vertex' sub tab of the MODO toolbox (under Commands') or users can select the command from the manu bar under "Geometry > Vertex > Set Position". Simply select a number of vertices and invoke the command.

Axis: Determines the plane with which to position the vertices.

Value: Determines the position to assign to the selected vertices.

Work Plane/World Space: Users can assign the position value based off of the 'World Space' position, or users may also select the 'Work Plane' option and position the selected vertices based on the current 'Work Plane' position.



Align Vertices

The 'Align' option allows users to align a selection of vertices into a straight row, as a line between the first and last vertex selected.

Axis: Confines the movement of the repositioned vertices to one or 'All' axes, or an axial plane (XY, YZ or ZX).

Uniform: When this option is enabled, the vertices will be evenly (uniformly) spaced along the span.



Join Vertices

Join welds the select vertices to the last vertex chosen, and moves them all to that position. Join works on multiple vertices as well.

Available on the Vertex tab of the MODO Tools toolbar, the Join command launches the Join Vertices dialog.

Average: When this is turned on, the selected vertices are welded into a single vertex positioned at an averaged distance between the selected points.

Keep 1-Vertex Polygons: When this is turned off 1 vertex polygons are automatically deleted. When this is turned off, if the join operation leaves a single vertex behind, it is allowed to exist.


Join Averaged

Join average welds two vertices together at a central position between the two vertices. Join average can weld multiple vertices as well.

To Join Average multiple vertices do the following:

1) Select the vertices you wish to join together into one vertex.
2) On the MODO Tools toolbar, click the Vertex tab.
3) In the Commands section click Join Averaged.
4) In the Join Vertices dialog, you should see a message telling you how many vertices were joined into one. Press OK to close this dialog.



Geometry Remove deletes the selected vertices, edges or polygons from the 3D Model View.

You can use the Remove command from the Vertex or Edges Tab of the MODO Tools toolbar, or choose Geometry > Remove. You can use the Backspace key or Delete to also remove vertices, edges or polygons. Geometry Remove works on individual or selected vertices, edges or vertices.



The Collapse command removes the selected element without destroying the integrity of the geometry. Any select polygon, edge or vertex is deleted but no hole is left behind. Instead, the mesh heals, closing any gaps by merging the neighboring elements together.

The Collapse feature can be found as follows:

Vertex: On the Vertex tab of the MODO Tools toolbar > Commands > Collapse.
Edge: On the Edge tab of the MODO Tools toolbar > Commands > Collapse Edges.
Polygons: On the Polygons tab of the MODO Tools toolbar > Commands > Reduce > Collapse.

You can also select whatever geometry you wish to collapse and then choose Geometry > Collapse.



Split Vertices is the opposite of the Join Vertex Command. Instead of combining multiple vertices into a single vertex, it takes a single vertex and creates multiple vertices in the same location, based on the number of polygons that share the point.

Unlike the Join command, Split Vertices creates the multiple vertices in their original location, it doesn't move them apart. Select any polygon or edge and move that to separate the split vertices.

Split Vertices can be found on the Vertex tab of the MODO Tools toolbar, under the Commands section. Or you can select the vertices, then choose Geometry > Vertex > Split.



Merge Verts Dialogue

The Merge Vertices command measures the distance between vertices in the currently selected geometry to see if any fall within a specific distance threshold to one another. If any vertices are within that range, they are combined into a single vertex. The resulting vertex is positioned at the site of the most recently selected vertex of the vertices merged.

By default the merge vertices function uses a Range setting of Automatic. This means that only vertices that share the exact location on all three axes will be merged. To increase the distance allowed between two vertices to be merged, use the Fixed option. When the Fixed option is selected, the Distance field allows you to set a distance threshold. For example, if the Distance value is set to one meter, any points that fall within one meter of another point will be merged together.

The "Keep 1-Vertex Polygons" flag is active by default as well. Often when merging vertices within a certain threshold, polygons become flattened into only one vertex. In this case they become 1-vertex polygons. These single vertex polys can cause rendering anomalies, and other issues in the model file when exporting to other systems. You can simply disable this option and all resulting single vertex polys will be removed.

The Merge Vertex command is found on the Vertex tab of the MODO Tools toolbar in the Tools section.
