The collapse transition of a single polymer chain in two and three dimensions was studied using the bond-fluctuation model. The obtained exponents ν of the scaling law ∼N2ν agree with values proposed in the literature as well as above, at and below the Θ-temperature TΘ. Transition curves and scaling analysis plots are presented. The scaling function α3SτN1/2 vs τN1/2 has a pronounced maximum before leveling off in the fully collapsed regime in accordance with the theory [α2S=/Θ, τ=|(T-TΘ)/TΘ|]. An analyzing of the subchain distances leads to disagreements with the blob model. The subchains are locally swollen for T>=TΘ and shrunken for T
