In Heal Model, you can fix all geometry errors, such as duplicated faces, small faces/edges, abundant vertices, holes. You can also modify any shape, such as replace edge from face, add vertex into edge, and so on.
To open Heal:
Click Heal(Geometry Tools toolbar) or click Geometry, Geometry Tools, Heal .
Heal contains four basic parts:
Face. It contains several methods to fix or modify faces.
Edge. It contains several methods to fix or modify edges on face, edges on wire or independent edges.
Vertex. It contains several methods to fix or modify vertices on edge.
Hole. It contains two methods to remove holes from face or shell.
The Face contains:
Duplicate. Search the duplicated or overlapped face pairs, and remove the small face.
Small Face. Search the small faces according to size threshold, and remove the searched faces.
The Edge contains:
Toggle. If one face can't be stitched well with neighbor face in Stitch dialog because the gap is larger than the tolerance, you can select the free edge to sew two faces together by a larger tolerance . Toggle is a manual stitching method.
Untoggle. If you want to make a shared edge from two faces into two free edges, you can use Untoggle to unstitch one shared edge.

a. raw shell |
b. toggle the gap by select one edge |
c. untoggle the top edge |
Replace. Replace the raw edge/wire with another edge/wire, the selected two edges/wires should locate at the same face.
a. Raw face and a projected wire on the face |
b. Replace the face bound wire with the projected wire |
a. Raw wire and an edge |
b. Replace the bottom edge |
a. raw two faces |
b. replace the right face's bound edge with the left face's bound edge |
Small Edges. Search the small edges by length and angle tolerance, and finally remove them from face.
a. Raw face |
b. Break points on the faces' bound |
Duplicate. Search the duplicated or overlapped edges.

a. Raw shell with two faces |
b. Tag the shared edge to suppressed edge |
c. Auto Mesh without using suppressed edge |
d. Auto Mesh using suppressed edge (Mesh across suppressed edges) |
The Vertex contains:
Add. Insert a vertex into a edge, it means break the edge into two sub edges according to the selected point position.
a. Raw face |
b. Add 3 vertices into the bound edges |
Move. Move a vertex on a edge to a specified position. The two vertex shouldn't be too far away.
a. Raw face |
b. New face after moving vertex |
a. Raw shell |
b. Shell after removing abundant vertices |
The Hole contains:
Inner Hole . Inner hole is the inner boundary of the face. Search the inner hole and remove it from face.
a. Raw faces |
b. Faces after removing inner holes |
Out Hole . Out hole is the outer boundary of the shell. Search the out hole and fill the gap of the shell.
a. Out hole of the shell |
b. Shell after filling out hole |
Hollow. Search hollow regions from shell or solid shape.
a. Solid contains many hollows |
b. Searching and removing hollows |
