Técnicas Autocad:
Sistema de Impressão em ADT 2.0 De entre os dispositivos de impressão podemos usar impressoras e plotters (dispositivos de hardware) ou de software (formatos de imagem por pontos de écran, ou DWF).
A impressão para DWF constitui-se na criação de um ficheiro com a extensão DWF, o qual é visto com um plug-in para o IE, chamado Volo view. O resultado desta operação é um ficheiro dependente do DWG que lhe deu origem, assumindo gráficamente a expressão determinada no page setup, mantendo algumas funcionalidades do Autocad, nomeadamente a possibilidade de manipular a visibilidade de layers, e de fazer zoom.
A relação de escala obtem-se diferentemente no modelspace e no paperspace, sabendo que para ambos os casos a unidade de referencia é o mm.

Cortes em superfícies After attaching a drawing as an xref or inserting a block, you can define a clipping boundary by using XCLIP. A clipping boundary can define a portion of a block or xref while suppressing the display of geometry outside of the boundary. Clipping applies to an individual instance of an xref, not the xref definition itself. The portion of the xref or block within the clipped boundary remains visible, and the remainder of the xref or block becomes invisible. The referenced geometry is not altered, only the display of the xref is edited. You can use XCLIP to create a new clipping boundary, delete an existing boundary, or generate a polyline object coincident with vertices of the clipping boundary. Xref clipping can be turned on or off. When a clipping boundary is turned off, the boundary is not displayed and the entire xref is visible, provided that the geometry is on a layer that is on and thawed. When a clipping boundary is turned off, it still exists and can be turned on. However, deleting a clipping boundary is permanent. For more information about XCLIP, see the Command Reference. After an xref or block has been clipped, it can be edited, moved, or copied just like an unclipped xref or block. The boundary moves with the reference. If an xref contains nested clipped xrefs, they appear clipped in the drawing. If the parent xref is clipped, the nested xrefs are also clipped. If you want to see the clipping boundary, you can turn on the XCLIPFRAME system variable. XCLIPFRAME determines whether the clipping boundary frame is displayed. When the clipping frame is on (set to 1), it can be selected as part of the object and plotted. For more information about XCLIPFRAME
