Repair a mesh body

00:04

After you insert or tessellate a mesh body in the design workspace,

00:08

the mesh body may contain errors that need to be repaired.

00:12

In addition to minor surface imperfections,

00:14

there are three primary errors you may need to repair

00:17

in order to use the mesh and downstream workflows.

00:21

A warning icon appears next to the mesh body

00:24

in the browser to indicate it contains errors.

00:27

If you hover over the warning icon, the relevant errors display

00:32

the mesh is not closed error displays when one or more holes

00:35

or missing faces prevent the mesh body from being water tight.

00:40

The mesh is not oriented error displays when one or more faces is

00:44

flipped in the opposite direction from the rest of the mesh body.

00:49

The mesh does not have positive volume error

00:51

displays when the majority of faces are oriented in a

00:54

direction that cannot produce a mesh body with positive volume.

00:58

For instance,

00:59

if the mesh is inside out,

01:02

you can click the warning icon to start

01:04

the repair command directly from the browser.

01:08

Let's use the repair command to repair a mesh body

01:12

on the toolbar, navigate to the mesh tab.

01:15

Then on the prepare panel, click repair

01:19

in the canvas, select the mesh body you want to repair,

01:23

you can check the preview box to display a preview of the repaired result.

01:27

Based on the current repair settings,

01:30

there are four repair types,

01:32

close holes, stitch and remove

01:35

wrap

01:36

and rebuild.

01:38

They range from minimal repairs with relatively short compute time

01:42

to a full rebuild of the mesh with longer

01:44

compute times based on the complexity of the mesh body

01:48

stitch and remove is selected by default.

01:52

The close holes. Repair type closes any holes it finds on the mesh body

01:56

and flips any faces that are reversed.

01:59

The stitch and remove repair type makes the same changes as close holes

02:04

and also stitches faces, removes double faces, removes,

02:08

degenerated faces and removes tiny shells.

02:12

Click OK to complete the repair command,

02:16

the mesh body is repaired.

02:18

The errors disappear from the browser

02:20

and a repair feature displays in the time line.

02:25

If you need to adjust the repair settings as you evolve your parametric design,

02:29

you can edit the repair feature and the mesh body will update to reflect your changes

02:35

in the timeline. Right. Click the repair feature.

02:39

The edit feature, dialog displays with your existing repair settings.

02:44

Set the repair type to wrap

02:46

the wrap repair type makes the same changes as stitch and remove

02:50

and also wraps the surface of the mesh body to ensure its water tight.

02:55

If the mesh body contains any interior

02:58

structures like unwanted holes supports or lattices,

03:02

they are removed.

03:04

Click. Ok.

03:05

And the converted mesh body updates in the canvas to reflect your changes,

03:11

you can also add multiple repair features to a parametric design.

03:14

If you want to perform a light repair first

03:17

and then a more targeted rebuild repair afterward,

03:21

set the repair type to rebuild

03:23

which reconstructs the entire mesh body using one of four rebuild types.

03:29

The fast rebuild type rebuilds the mesh body quickly but not accurately.

03:34

In any of the four rebuild types,

03:36

you can adjust the density value to increase or decrease

03:39

the number of faces on the repaired mesh body.

03:44

The preserved sharp edges rebuild type maintains any sharp edges from

03:48

the original mesh body to provide a slightly more accurate result.

03:54

The accurate rebuild type provides a more accurate

03:57

result but takes a bit longer to compute.

04:00

In addition to density,

04:02

you can also offset the repaired mesh body from

04:05

the original mesh body by a specific distance.

04:09

The blocky rebuild type reconstructs the original mesh in a blocky style

04:16

when you're happy with the result. Click. Ok.

04:19

And the mesh body updates in the canvas to reflect the new repair.

04:23

A second repair feature displays in the timeline.

04:26

So you can always edit its settings separately from the first repair feature.
