Por Augusto Gon\u00e7alves<\/strong>, Autodesk Developer Network<\/a><\/p>\n

Neste post irei mostrar como numerar as curvas de bordo de um alinhamento utilizando VB.NET. \u00c9 necess\u00e1rio ter completado o exemplo do post anterior<\/a>.<\/p>\n

O objetivo geral \u00e9, em um dado alinhamento, por exemplo em verde na figura abaixo, localizar as curvas de bordo e escrever um texto indicativo numerado, por exemplo, \u201cCurva = 1\u201d.<\/p>\n

\"resultado_final\"<\/a><\/p>\n

Para numerar as curvas, \u00e9 necess\u00e1rio descobrir a ordem. Sempre que trabalhamos com programa\u00e7\u00e3o, temos que elaborar uma regra inequ\u00edvoca para determinar a quais curvas ser\u00e3o consideradas e a ordem.<\/p>\n

Ent\u00e3o algumas regras deve ser adotadas: deve existir um Alinhamento do Civil 3D como refer\u00eancia, as curvas de bordo devem ser do tipo Arco do AutoCAD, e estes arcos devem estar at\u00e9 uma dist\u00e2ncia m\u00e1xima do alinhamento. Estas regras definem quais arcos ser\u00e3o considerados.<\/p>\n

Para determinar a ordem iremos determinar qual a estaca mais pr\u00f3xima do centro do arco que representa a curva de bordo (ver figura abaixo). Esta ordem deve ser definida no sentido de crescimento das estacas. Desta maneira, independente do lado, a numera\u00e7\u00e3o dos arcos ser\u00e1 definida pela estaca onde o centro do arco est\u00e1 projetado.<\/p>\n

\"visao_geral_curvas\"<\/a><\/p>\n

Dica: embora possam parecer \u00f3bvias, as regras que ser\u00e3o implementadas em programa\u00e7\u00e3o devem ser o mais especificas poss\u00edveis. Regras fracas levam a rotinas que podem falhar (produzir resultados inesperados).<\/p>\n

Preparando para o c\u00f3digo!<\/span><\/strong><\/p>\n

Partindo do projeto do post anterior, inicie o Visual Basic 2010 Express, abra o projeto ProjetoCivil3DBR<\/strong>. Na janela de Solution Explorer<\/em>, clique com o bot\u00e3o direto no projeto e escolha Add,<\/em> em seguida a op\u00e7\u00e3o Class<\/em>. No formul\u00e1rio que se abrir\u00e1, digite o nome da classe, neste exemplo CurvasBordo<\/strong>.<\/p>\n

\"menu_add_class\"<\/a><\/p>\n

\"classe_curvas_bordo\"<\/a><\/p>\n

Na pr\u00e1tica n\u00e3o \u00e9 necess\u00e1rio criar uma classe para cada novo comando, mas iremos adotar esta abordagem para facilitar a organiza\u00e7\u00e3o. A nova classe ser\u00e1 criada em um novo arquivo .vb do projeto.<\/p>\n

API de busca e ordena\u00e7\u00e3o<\/span><\/strong><\/p>\n

Na pr\u00e1tica vamos sempre assumir que uma lista de qualquer coisa estar\u00e1 fora da ordem desejada. Para este exemplo, temos que selecionar todos os arcos, filtrar pelos que est\u00e3o at\u00e9 uma determinada dist\u00e2ncia m\u00e1xima do alinhamento, e orden\u00e1-los pela estaca.<\/p>\n

A API do Civil 3D n\u00e3o incluir m\u00e9todos para filtros muito espec\u00edficos ou ordena\u00e7\u00e3o, mas por se tratar de uma API .NET, podemos utilizar recursos nativos da plataforma VB.NET. E isto vale para (praticamente) todos as maravilhas do .NET! Espetacular!<\/p>\n

Para filtro e ordena\u00e7\u00e3o, dentre outros, temos uma API do .NET chamada LINQ (Language-Integrated Query<\/a>), que existe desde a vers\u00e3o 3.5 e \u00e9 extremamente \u00fatil. Vale a pena estudar um pouco.<\/p>\n

Nota<\/strong>: Civil 3D 2012, 2013 e 2014 usam .NET 4.0.<\/p>\n

Hora do c\u00f3digo!<\/span><\/strong><\/p>\n

Como no exemplo anterior, todas a linhas de c\u00f3digo que come\u00e7am com \u2018 (aspas simples) s\u00e3o coment\u00e1rios e ficam verde no Visual Basic 2010 Express. Utilizamos coment\u00e1rios para explicar o que um conjunto de linhas de c\u00f3digo ir\u00e1 executar. N\u00e3o \u00e9 necess\u00e1rio, ou pr\u00e1tico, comentar todas a linhas de c\u00f3digo, apenas o que for necess\u00e1rio.<\/p>\n

O c\u00f3digo abaixo come\u00e7a de maneira similar ao c\u00f3digo do post anterior, com CommandMethod. <\/em>Esta marca\u00e7\u00e3o (atributo em .NET) define o nome do comando no AutoCAD Civil 3D. Ou seja, sempre que digitarmos N<\/strong>UMERARC<\/strong>URVAB<\/strong>ORDO na linha de comando, iremos executar a rotina deste comando.<\/p>\n

Este comando requer que o usu\u00e1rio selecione um alinhamento e digite uma dist\u00e2ncia. Temos que garantir que isso ocorra, caso contr\u00e1rio o comando n\u00e3o pode prosseguir. Observe o Exit Sub<\/em> quando o resultado da sele\u00e7\u00e3o n\u00e3o \u00e9 OK (o c\u00f3digo <> significa diferente).<\/p>\n

Em seguida selecionamos todos os arcos do model space<\/em>. Estes arcos ser\u00e3o filtrados pela distancia m\u00e1xima e ordenados pelo estaca, resultando na cole\u00e7\u00e3o curvasBordoFiltrada<\/em>. Esta cole\u00e7\u00e3o ser\u00e1 utilizada para a cria\u00e7\u00e3o dos textos indicativos (similares ao label<\/em>).<\/p>\n

Agora copie o c\u00f3digo abaixo, cole no arquivo CurvaBordo.vb<\/span> aberto no Visual Basic 2010 Express. O resultado deve ser como na imagem abaixo. Retire eventuais linhas em branco.<\/p>\n

Agora com o c\u00f3digo inserido no Visual Basic 2010 Express, v\u00e1 ao menu Debug, <\/em>escolha a op\u00e7\u00e3o Build ProjetoCivil3DBR, <\/em>da mesma forma que foi feito para o exemplo do primeiro post.<\/p>\n

\"build_DLL\"<\/a><\/p>\n

Finalmente abra o Civil 3D, execute o comando NETLOAD, escolha a DLL na pasta Release<\/em>. Assim como no exemplo do primeiro post, a DLL deve estar na pasta:<\/p>\n

\u2026\\ProjetoCivil3DBR\\ProjetoCivil3DBR\\bin\\Release\\ProjetoCivil3DBR.dll<\/strong><\/p>\n

O novo comando est\u00e1 pronto, execute N<\/strong>UMERARC<\/strong>URVAB<\/strong>ORDO, selecione o alinhamento, especifique a distancia m\u00e1xima e pronto. O textos ser\u00e3o desenhados no projeto do Civil 3D.<\/p>\n

No pr\u00f3ximo post iremos incrementar este comando para desenhar uma tabela de curvas, com raio, comprimento, PC e PT.<\/p>\n
