I'd like to know if it's possible to increase the thickness of a brace.

The code



\newcommand{\veu}{\ve u}
\newcommand{\vev}{\ve v}

            q_1(\veu) \land q_1(\vev) &= \begin{vmatrix}
                u_2 & v_2\\
                u_3 & v_3
            \end{vmatrix} = u_2v_3 - u_3v_2 = 0\\[1.5em]
            q_2(\veu) \land q_2(\vev) &= \begin{vmatrix}
                u_1 & v_1\\
                u_3 & v_3
            \end{vmatrix} = u_1v_3 - u_3v_1 = 0\\[1.5em]
            q_3(\veu) \land q_3(\vev) &= \begin{vmatrix}
                u_1 & v_1\\
                u_3 & v_3
            \end{vmatrix} = u_1v_3 - u_3v_1 = 0

The result


I think the brace is a bit too thin, and I tried to replace cases with a manual \left\{ but that didn't work.

    Always post full minimal examples. Also cases already use \left\{ so it will not help much.

  • @daleif I think I posted a full minimal example. There's the template at the top so that it does not have to be repeated two times.

  • @daleif If that's the case, I'll change my question to: "How to make a thicker brace?"

    This answer by egreg, tex.stackexchange.com/questions/35891/…, also goes to the heart of it, though isn't quite the same as the earlier reference I gave. Mar 4, 2015 at 11:50
