Как да преместите чертежа надолу, за да добавите заглавие
Проблем: Как да преместите чертежа надолу, за да добавите заглавие (CADNET-980).
Съвети: За да постигнете това, създайте обект CadText с параметри, добавете този блок към чертежа, след това актуализирайте чертежа с новите размери с UpdateSize, добавете полилиния, която е рамка около чертежа, добавете полилинията към BlockEntities["*Model_Space"] и отново актуализирайте с UpdateSize.
