Can I skip the value from the label to mark it?

[soo]

Hi

I'm making a label for Finishing materials.

there is a problem to solve that I want to skip the value named AIR but i don't know how to skip it.

For example, in this picture Even if the slab contains 4 materials, I don't want to label the material named AIR.

this is the scripts i used.

for i = 1 to numText

if (fra(MATthk[n]*1000) > -eps and fra(MATthk[n]*1000) < eps) then
thk = str("%.0mm", MATthk[n])
else
thk = str("%.1mm", MATthk[n])
endif

autotxt[i] = "T" + thk + " " + MATname[n]
autoTHK[i] = MATthk[n]

I don't see how to exclude the value MATname[n] = "AIR" in the middle of this root.

Even if i force it to make it by removing the value, it was only marked as zero, but it was not completely removed.

I want only three expressions: AA, BB, and CC on my label.

Like this picture.

Please help me to solve this problem.

thank you.

a simple if statement inside the loop should do the trick:

if (MATname[n] = "Air") then

autotxt[i] =""

else

autotxt[i] = "T" + thk + " " + MATname[n]
autoTHK[i] = MATthk[n]

endif

After that I asume you loop over autotext[] to get the lines of the label, so you can check for autotext[i] lenght and if it is less than 1 you can skip it.
