It is a modified G-pen that allows you to draw straight lines freehand. Even if I draw a slightly distorted line, I try to correct it straight by aligning the start and end points.
It is useful when drawing objects with many straight lines, such as firearms, weapons, buildings, and three-dimensional objects.
フリーハンドで直線を描ける改造Gペンです。少し歪んだ線を描いても、始点と終点の位置合わせで真っ直ぐに補正が効くようにしています。
銃器や武器、建物、立体物など直線が多いものを描くときに役立ちます。
