3DAce can be operated fairly intuitively to a certain extent,

but there are some unique operations,

so if you are using 3DAce for the first time,

please read this first.

■ First, Try Moving Things Around Freely ■

When you start it, there is an object in the center from the beginning (it's fine to delete it), try clicking around in the locator window or clicking toolbar buttons and playing around. You should be able to move things fairly intuitively.

Then, you will probably have questions or requests about the operations. (Likely, symmetric points, selection-related, and camera-related things will catch you.)

So, I want you to know the following first.

　

[Symmetric Points]

In 3DAce, there are symmetric points where if you move one point, etc., the other point moves symmetrically with respect to the X-axis to match it. This is a very convenient feature where when creating left-right symmetric objects, you only need to create one side, and the other side's object is created in real time automatically.

　

Separate from symmetric points, there are independent points, which are ordinary points that do not affect other points.

You can switch between symmetric points and independent points at any time.

　

If you select symmetric points together, you cannot move in the X-axis direction (because of left-right symmetry, there is no way to move). Similarly, rotation, scaling, etc. become strange when selecting symmetric points together. (That said, once you get used to the quirks, you can operate normally.)

　

■ When movement or other actions do not behave as expected, it is almost always because you have selected symmetric points together.

　

[During Selection]

In 3DAce, while holding Shift key for selection inversion, Shift + Ctrl for selection addition, Ctrl for selection deselection.

　

When performing [Move] [Rotate] [Scale] [Normal Move], if you directly select selected items while holding Ctrl or Shift, it will not deselect, but instead perform extrusion (extension) or quick copy.

For deselection etc., do not select directly; use range selection state for inversion or deselection.

　

■ Symptoms like points increasing without noticing midway are almost always caused by this, so be careful.

　

[Camera]

If the object goes somewhere off-screen, perform [Full Range Zoom] (the button with a gray square on the right side of the toolbar. Shortcut is A). It will zoom so that the object fits within the screen range.

　

If you want to rotate centered on the selected object, perform [Selected Point Zoom] (the button with a white square on the right side of the toolbar. Shortcut is Shift + A). It zooms so that the selected object fits in the screen, and the camera rotates centered on that object.

　

If you lose track of which way you are facing, double-click the locator (double-click in camera state, or Alt + double-click in the window is also OK). It faces front.

　

If you want to rotate the camera exactly to an axis, roughly align the direction that way, then single-click the locator. (Single-click in camera state, or Alt + single-click in the window is also OK.) It faces the axis direction closest to the current viewpoint.

　

■ If you know just these operations, you shouldn't have to worry about camera-related things for the time being.
