i creat a house, then built it (map), using this format help me spend short time than using block, so what wrong?how this way?....please show me some idea....

What exactly are you asking? You created a map entity (house) and then?

You created a House in .map format?,using UnrealEd/Quake...what Editor?. You need to be specific...try to explain.Many people here will help you including myself.

it's mean: i use map for house in my world, map usually use for door, transport...but i use map for house, building, stair...in my world. Do you understand? why i ask this? because before i make house,floor,wall...when i build level, i spent long time to build it. But when i use map format it need short time to build...It same time to build a model very very short, before i need 1hours to build but using map format i need only 2 or 3 munite. Sorry everyone, my question not clearning....very very sorry..because i'm vietnames...i learning english not much.......so very bad....sorry

Thats because map entities are already compiled, when you compile map in wed build button, you are compiling the objects you select like geometry (blocks), models, etc, thus its loading time is short in the level. You may check the manual in the entities section, where it explains the pros and contras of each format and when each format should be used.
