There is one other reference point above the center. The referent point at the center of the viewport can be used to move the viewport around on the layout. A selected viewport shows reference points at the corners which can be used to adjust the the size of the viewport. Just like other entities, viewports can be selected by clicking them. Viewports can be created using Draw > Viewport > Add Viewport Adjusting Viewports New layout blocks can be added as required using Block > Add Layout Block. The same data is shown twice, through two different viewports at two different scales.Įvery new drawing automatically has a layout block. However, there is no duplication of data. The detail B 1 shown in our example is shown twice in the layout: once in the overview at the left and again, at a larger scale at the right. The contents of a viewport can be hidden using the special viewport property "On". Note that the layer does not control the visibility of the viewport contents. The layer with the viewports is also usually made unplottable which means that the rectangular viewport borders are not printed. The layer with the viewports on it can be switched off to hide the rectangular viewport borders. The layer also controls the visibility of the viewport border.
The layer controls the appearance of the viewport rectangle (in our example orange and dashed). Just like any other entity, every viewport is placed on a layer. You can also think of a viewport as a special kind of a block reference that always references the model space block and is clipped at a given size. It shows a part of the drawing model in a layout. A viewport can be described as a window to the drawing model. The rectangular areas with a dashed orange border in the layout above are called viewports. These are the orange, dashed rectangles shown above. In addition, a layout usually contains viewports. A layout block can also contain any kind of own drawing elements, but usually contains a drawing border and a drawing header or legend. The objects shown inside the orange, dashed borders have not been copied or scaled and when the drawing model is changed at any point, the layout immediately reflects these changes. It is important to understand at this point, that this is still the same drawing. If you switch to the first layout (listed as "Layout (*Paper_Space)" in the block list), you can see that the same drawing has been re-arranged, a border has been added and a detail of the drawing is shown at a different scale: It is usually not arranged in the way the drawing should be printed. The geometry is typically arranged in any way that happened to be convenient for constructing it. When you open the drawing in QCAD, you can see the model space where all the geometry is created in real size. Each part of the drawing can be shown at a selected scale and angle.Ĭonsider the example " flange.dxf" which comes with every installation of QCAD.
A layout shows one or multiple parts of the drawing, often accompanied by a drawing border and drawing header. In other words, this is where you create the geometry of your drawing.Ī layout (also "layout block" or "paper space") is another special type of block that is usually used for printing a drawing or parts of a drawing. This is a special block which holds the main drawing in real size (1:1). When starting a new drawing in QCAD, the model space (also "model" or "drawing model") is shown. Use View > Block List to show the block list. The block list shows all blocks of a drawing, including the model space block and layout blocks. When working with layouts, make sure that the block list is shown.
A layout shows how the drawing will be printed. A layout is an arrangement of parts of the drawing, accompanied with a drawing border and possibly other elements. This tutorial introduces an advanced concept in QCAD to print drawings by creating a layout.
