How can I check the existence of block by command?

Hello.

I'm making a macro program.

This function needs a block and if there's no block, the function doesn't work and block form pops.

So, I want to put in a command which checks the existence of block before main commands.

But I couldn't find the command or parameter.

Eventually, I check the type of the block and check its scalar parameters.

For example, if the type is 'box' then check X, Y and Z lengths are larger than 0 or not.

But I think this way is bizarre and not clean.

If there is a way to check the existence of block more cleaner, please let me know.

I would be glad if you reply.

Thank you.

Try this........

string BLK_TYPE = ""

$BLK_TYPE = block.type

REAL $X_range = $block.Limits.Xmax - $block.Limits.Xmin

REAL $Y_range = $block.Limits.Ymax - $block.Limits.Ymin

REAL $Z_range = $block.Limits.Zmax - $block.Limits.Zmin

IF ($X_range == 0) {

IF ($Y_range == 0) {

IF ($Z_range == 0) {

}

Message warn "No block exists"

} ELSE {

message info $block.type

}
