零件环境中的 TikZ 图形

我想在parts- 环境中显示 TikZ 图形，但图形出现在 (a) 部分上方而不是下方。我怎样才能让图片跟随 (a)？感谢您的帮助！

图片与其底部（基线）对齐。\savebox 用于计算图片的高度，以便将其降低到 a 部分以下。

\newsavebox{\hold}
\newlength{\holdht}
\newcommand{\lowerit}[1]{% #1 = picture
\savebox{\hold}{#1}%
\settoheight{\holdht}{\usebox{\hold}}%
\raisebox{-\holdht}{\usebox{\hold}}%
