why won't this work?

float boxcenter[3];

if (nodectr == 0)
boxcenter = {centerpt[0] + halfwidth/2.0, centerpt[1] + halfwidth/2.0,
centerpt[2] + halfwidth/2.0};

Because C doesn't do array assignments. You can, however, do a
declaration with initialization upon entering a block:

{
float boxcenter[3] = {centerpt[0] + halfwidth/2.0,
centerpt[1] + halfwidth/2.0,
centerpt[2] + halfwidth/2.0};

assuming that enterpt and halfwidth are defined on entry.
