PlyEdit: G - Mark

Marking lets you select faces in various ways for later hiding, smoothing or removal. There are several marking operations, all accessed via the <G> key. Marked faces are drawn green, that's why the <G> key is used.

Figure 1. Marking Menu

Figure 1 shows you what you get once you have hit the <G> key; a handy reference to the various operations towards the bottom of the window.

Marking Inside a Box - <LMB>

You can draw out a box by holding down the <LMB> while dragging the mouse. Let go of the mouse button and all faces inside the drawn box will be marked (see Figure 2). This includes faces that might be on the other side of the object, obscured behind the faces at the front. Hidden faces will not be marked.

Figure 2. Marking Inside a Box

Unmarking Inside a Box - <RMB>

Draw out a box using the <RMB> and all faces inside the box will be unmarked (see Figure 3).

Painting - <G> key

You can use the mouse pointer to mark faces in a more interactive way using the painting method. By typing <G> a second time you'll paint a single dot under the mouse pointer. Unlike the box selection method, only the faces you can see are marked; the painting doesn't go all the way through the object.

Figure 4. Painting

If you want to paint more than one dot, just hold down the <G> key and faces will be marked wherever you move the mouse pointer (see Figure 4). When you want to stop painting, let go of the <G> key.

If you want to unmark using the painting method, use <Shift-G> instead.

Brush radius - <-> and <{{{1}}}> keys

You can change the size of the painting brush with the <-> and <{{{1}}}> keys. Aim the mouse pointer at some part of the mesh so you can see what effect these keys have on the size of the brush.

Filling - <F> key

To mark an area of unmarked faces in a flood fill fashion, move the mouse pointer into some part of that area (see left side Figure 5) and type <F>. The flood fill will not cross a boundary of already marked or hidden faces ( see right side Figure 5).

Figure 5. Filling

In Figure 5 the smile of the face has been extended to fully encircle the ankle, before filling, otherwise the whole leg would have been marked.

You can unmark using the flood fill method by just pointing the mouse pointer at an area of marked faces before filling.

Swapping - <S> key

To swap the marked and unmarked status of all visible faces, type <S> (see Figure 6).

Figure 6. After Swapping

Unmarking - <U> key

To unmark all visible faces, type <U>.
