How to limit the BATCH of b3dm in 3D tiles\_ The value of the LENGTH parameter, I only want to allow BATCH\_ LENGTH equals 1。  
for example ：b3dm DL € € {“BATCH\_LENGTH”:1} {“OBJECTID”:{“byteOffset”:0,“componentType”:“SHORT”,“type”:“SCALAR”},“hh”:{“byteOffset”:8,“componentType”:“DOUBLE”,“type”:“SCALAR”},“qsc”:{“byteOffset”:16,“componentType”:“DOUBLE”,“type”:“SCALAR”},“featuregui”:[“{2572F5BD-51AD-4481-9DA3-B0406A8DB504}”],“fh”:[“BG11”],“st\_perimet”:{“byteOffset”:24,“componentType”:“DOUBLE”,“type”:“SCALAR”},“SHAPE\_\_ID”:{“byteOffset”:32,“componentType”:“DOUBLE”,“type”:“SCALAR”},“zddm”:[“370212002523GB00051”],“zdguid”:[“{6450A86F-8C8E-4A0E-BA08-7B66A147EA12}”],“sctnjzmj”:{“byteOffset”:40,“componentType”:“DOUBLE”,“type”:“SCALAR”},“tnjzmj”:{“byteOffset”:48,“componentType”:“DOUBLE”,“type”:“SCALAR”},“scftjzmj”:{“byteOffset”:56,“componentType”:“DOUBLE”,“type”:“SCALAR”},“bdcdyh”:[“”],“hxh”:[“BG11”],“hguid”:[“{2572F5BD-51AD-4481-9DA3-B0406A8DB504}”],“ljzh”:[“1”],“scjzmj”:{“byteOffset”:64,“componentType”:“DOUBLE”,“type”:“SCALAR”}
