5-2. Magnet function (Point-to-point adsorption function)

This section introduces the Magnet function that attracts points and points, which is useful for modeling.

Step 1 (Load model)

First, load the TV monitor model (SATURN_TV_SET) created in Chapter 2 before using the Magnet function.
[Get] → [Element] → [MODELS]
After loading, it should look like the figure below (Figure 5-9).

Figure 5-9 For TV monitor

Step 2 (Delete CRT polygon)

Change from OBJ mode to TAG mode, and add TAG to the points in the figure (Figure 5-10).

Figure 5-10 Add TAG

Then
[Delete] → [Selection]
Please run the. (Do not remove TAG yet)
The polygon corresponding to the CRT should have disappeared (Figure 5-11).

Step 3 (Put one polygon)

Then
[Get] → [Primitive] → [Grid] please choose. The “Create Rectangular Grid” window will appear (Figure 5-12).

Figure 5-12 Create Rectangular Grid setting screen

Enter “0.5” for “X Cell Size”, “0.5” for “Z Cell Size”, “1” for “X Cell Count”, and “1” for “Z Cell Count”.
Make sure “Polygon” is checked and click “OK”.

Then, the following figure appears, and one square polygon appears (Figure 5-13).

Figure 5-13 Creating a single polygon

How to put out one polygon

In the future, use [Get]-> [Primitive]-> [Grid] to get a single polygon like this.

Step 4 (Rotate 1 polygon)

I think that one polygon is currently selected, but here select OBJ mode and click the corner of the triangle in the “Rot” icon.
When the numeric input window opens, enter X: 90, Y: 0, Z: 0 and click “Set”. The selected single polygon rotates as shown below (Figure 5-14).

Figure 5-14 Single polygon rotation

[Effect] → [Freeze] → [Rotation]
Please run the.

Step 5 (Adsorption function setting)

The next thing to do is to fit this single polygon into the TV monitor with a hole. First, in this step, the adsorption function is set.

There is a ruler shaped icon in the bar on the Perspective screen (Figure 5-15).

Figure 5-15 Ruler type icon

Clicking this icon opens the “Layout Perspective” window as shown below (Figure 5-16).

Figure 5-16 Layout Perspective setting screen

There is an item "Magnet" in this.
I think that “Off” is checked by default, but check “On Point”. Make sure that “Unselected Objects” on the right is checked and click “OK”.

In the screen that has been set, try to pick an arbitrary point on a single polygon with the "M" key + any mouse button . Then, the point moves as shown in the figure (Figure 5-17).

Figure 5-17 Moving point with “M” key

If you try to move it, undo it for the time being ( "U" key + left mouse button ).

Magnet function

As you can see, the Magnet function is a function that attaches the picked point to a certain point. However, please note that this function works only in the set window.

“On Point” and “On Tag”:

While “On Point” picks the point you picked, it sticks to another point, while “On Tag” sticks to the TAG point.

“Unselected Objects” and “All visible Objects”:

“Unselected Objects” is a function that attaches the picked point to the point of the object that is not currently selected (in this case, the target is a TV monitor), and “All visible Objects” is a list of all visible objects. Attach to the point. In this case, not only the TV monitor,
