Introduction of Metasequoia 4's useful features
(4) Usage of Mirroring objects and Edit options

We continue to develop Metasequoia 4 to make it easier for more users.
However, new users or users who have used the software after a long time may miss Metasequoia's features.
In this article, we will introduce some of the features we haven't introduced in detail in the past.

Usage of Mirroring objects and Edit options

With [Mirroring] objects, you can easily create symmetrical objects.

[Mirroring] halves the effort of modeling symmetric objects. This is a commonly used technique for modeling human body etc..

When mirroring editing, the coordinates of the vertex that should be at the center of the object may deviate from X = 0. Then, cracks will be made in the mirror object surface.

Let's fix cracks easily. And set [Edit Option] to prevent unintentional shifting of the vertices.

Restring the position of shifted vertices

(a) Snap to Plane

If there are a little vertices to fix, it is solved by [Snap] to attach the vertices to the YZ plane(X-axis). Check [Snap > Plane] in [Edit Option]. And, click on the tool mark to open the settings dialog.

In [Plane Snapping] section, select [X] and press [OK]. While [Snap] is enabled, the edited vertex will be attached to the X = 0 plane (YZ plane).

Select the vertices that need to fix. Move a little by [Move] command. The vertex is automatically moved to the position of coordinate X = 0, and the crack is fixed.

After fix is completed, disable [Snap].

(b) Align the coordinates of multiple vertices

If there are many vertices to be corrected, change the coordinates at once using [Align vertices].

First, select the vertices on the centerline by [Route] selection of [Select] command. There is no problem if the selection contains vertices that do not require modification.

Select [Selected > Align Vertices] in menu.
Input coordinate 0 to [Position] of [X] and check [Apply]. Remove [Apply] of [Y] and [Z].

Click [OK] to align the coordinates of multiple vertices.

To prevent the deviation of the vertex X coordinates

Next, I will show you how to prevent the deviation of the X coordinate of the vertices as much as possible.

One way is to use [Snap]. However, if you use [Snap], vertices other than the center will be attached to X = 0 also.
You can restrict movement in the X-axis direction in [Edit Options] without [Snap].

The [X / Y / Z] button at the top of the [Edit Option] sets whether to allow editing in each axis direction. Click [X] and disable editing to X-axis direction.

Try moving a vertex by [Move] command. A vertex can not be moved to the X-axis direction. But it can be moved in other directions.

The same restrictions apply to vertices other than on the centerline. If you need to move to the X direction, use the red arrow handle for X-axis instead of the yellow square at the center of the handle. Arrow handles can be operated under restrictions.

Please use them according to the operation you want to do.
