29.2 Graphics windows in paper space

Automatically, in the paper space we can see a presentation of the set of objects drawn in the model space. In appearance, both spaces are the same, except for the fact that we can see the outline of the sheet to be printed. That is, now the limits of the drawing are defined by it. However, we can also see that there is an outline around what is drawn. If we click on it, or if we select it with any of the methods we know, we will see that it presents grips, like any other object. This would imply that the outline of the drawing is, in turn, an editable object.
What happens is that said object is actually a Viewport. We can define these windows as display areas of the model from the presentation. These windows are also called “floating”, because we can not only modify their shape, but also their position within paper space. Also, in this space, we can add as many floating or graphical windows as we want to achieve presentation effects like the one we saw before the Opera House.
If we have two or more graphic windows in the paper space, each one will present a view of the model, even with different scales, perspectives and perspectives independent of each other, if desired.

To create a new graphic window we must use one of the options of the drop-down button of the section Graphical Presentation Windows of the Presentation tab. In previous versions of Autocad these options were available in the View tab, in the Graph Window section as you will see in the video (and its corresponding addendum). In any case, you will notice that we can create a graphic window in rectangular, irregular presentations with a closed polyline or using any other object, such as a circle or an ellipse.

Inside the newly created windows we can see the drawing as it is arranged at that moment in the model space. It is possible to select the graphic windows to present grips, which will allow us not only to move them, but also to apply some of the editing tools by grips that we studied in the 19 chapter, as we saw earlier.
We also have the option to create a presentation from a default graphic window arrangement. To do this, we use the Saved button in the same section and in the dialog box we use the New windows tab, where you will find a list of the different provisions that have already been given to save work. The disadvantage of these arrangements, if anything, is that in all cases they are rectangular graphic windows. The arrangement is concluded by indicating with the cursor the space that these windows will occupy.

Obviously, once an array of graphic windows has been created with this method, it is still possible to edit it using grips, resizing each window, moving it, deleting it, and so on.

So far we have seen how to create floating windows and even how to modify them, however, with that the window always presents the model in the same way, so now we must study how to modify the view of the model in the graphic window and, if it is necessary, to the model itself.
If we select a graphic window, we can use the scale control of the status bar. This is an exact method to determine the scale of the drawing in the paper space, important data in the drawing box. Once established, we can immobilize the view, to avoid accidental modifications. This option is also available in the status bar, or in the context menu when the window is selected, that is, when it presents grips.

Obviously, it is most likely that we will need not only to set the scale of the drawing inside the window and freeze that view, but also to be able to fit it within the limits of the window to highlight some detail or better center it. In the case of 3D drawings, it may also be necessary to use an isometric view, one of those that are preset in Autocad, within the graphic window. To do this, we can use all the Zoom tools we saw in Chapter 13 and Views in Chapter 14, but for them to take effect, we first need to double-click inside the viewport, which will “open” the viewport. the model space.

When a graphic window is highlighted in this way, we can even edit and modify the drawing of the model space, but in reality it is not recommended to make changes to the design from a floating graphic window, since it is finally a very limited area with respect to the model space in yes.
On the other hand, the advantage of being able to draw objects in the paper space, not residing in the model space, not only lies in the fact of being able to convert those objects into graphic windows, but also, to be able to add in our work elements that only have sense in the printing of plans, such as boxes and frames.

29.3 Graphic windows in model space

Graphic windows also exist for the model space, but their purpose is not to serve for the design of the print, but to make them an additional drawing tool, that is why they have some fundamental differences with their peers in the paper space.
First of all, model space viewports cannot be floating, but only “tiled”, with one of the preset arrangements in the “Viewports” dialog that we introduced on previous pages. And even in this mode, it is not possible to indicate any distance between windows.
As the purpose of these windows is to facilitate the drawing, just click on any of them so that we can add new objects to the drawing, which will be immediately reflected in the other windows. This, of course, is quite useful in the context of drawing 3D, since we can have each window with a different view.
Another difference with respect to the graphic windows of the paper space, is that we can choose another arrangement of graphic windows in mosaic and apply it to the active window. Let's see.
