Dúvidas sobre as bibliotecas de símbolos

As bibliotecas de símbolos DWG são grátis?
São. Toda biblioteca desta página é um download gratuito: um ZIP por arquivo DWG, com prévia de cada símbolo antes de baixar.
Como achar um símbolo rápido?
Digite o nome (“gate valve”), uma designação (“IPE 200”, “DN100”, “M8”) ou o nome de um bloco na caixa de busca. Os filtros à esquerda restringem as bibliotecas por setor, finalidade, norma e tipo, e a busca funciona dentro do que os filtros deixarem. Os nomes dos símbolos estão em inglês.
Que normas as bibliotecas seguem?
Cobrimos ISO, IEC, ISA, IEEE / ANSI, ASME, EN / DIN e AISC, por exemplo IEC 60617, ISA 5.1, ISO 10628-2, ISO 1219-1, ISO 1101 e ISO 14617. Onde não existe norma (arquitetura, HVAC, equipamentos de processo, tratamento de água, metalurgia), as bibliotecas seguem a prática comum da área e avisam isso na própria página.
Os símbolos são cópias certificadas das normas?
Não. Os símbolos são desenhos nossos, feitos a partir das formas usuais dessas normas; não são cópias das normas nem têm certificação de conformidade. Quando o cliente exigir conformidade estrita, confira as formas com a sua própria cópia da norma.
O que um bloco tem além do desenho?
Todo bloco leva atributos: uma tag visível e, ocultos, os dados que uma lista ou tabela de equipamentos precisa, como serviço, tamanho, classe, fabricante e modelo. Os símbolos de planta são desenhados em tamanho real, em milímetros; os símbolos esquemáticos, no tamanho de plotagem.
