一个关于ug表达式的问题

mfcad

这个是一个错误的表达式，该如何写？

double origin[3] = {0.0,0.0,0.0};
char *hight_exp = "hight=500.0";

UF_MODL_create_exp(hight_exp);
char *diam[2] = {"base=60.0","top=20.0"};
double direction[3] = {0.0,0.0,1.0};

tag_t cone_tag;

UF_MODL_create_cone1(UF_NULLSIGN,origin,hight_exp,diam,direction,&cone_tag);
