All models, which are located on the site were sent by the different authors or they laid out themselves for the free running off on the sites. If there is the author of model and it does not desire to see its model on my site - he writes me about this applying the confirmation of its authorship. If he wants the explicit indication of its authorship - he writes me about this and 4 this I make. If references are necessary - write, 4 with their pleasure I will place. In entire lifetime of the site of such it was 3 pritenzii and all models were without delay removed and brought izveneniya. I propose to go in this way. It obtained from your forum not of odnog of letter 4 also about such passions it learned randomly analyzing traffic. Apropos of models DWG - these are the freely extended models of firms - producers. Previously I please forgiveness for my English - this is machine transfer. With the respect Andrey Sergeev
