You can easily rescale your drawing using the Land F/X Scale tool. It simply changes the number of "units" in the drawing to match the new scale we're about to set. In our example, changing the number of units in our line will not make the line longer or shorter – as long as we rescale the drawing correctly. This is the traditional method used with single-view drawings. 1 (ratio between 10 mm in paper space and 100 cm in model. Example: To set the viewport to a 1: 100 scale when the drawing is in centimeters and the layout is set to millimeters, enter 0. There are three methods used to create dimensions in a drawing layout: Dimension in model space for plotting in model space. Select an existing scale from the Standard scale option, In the Custom scale option, type the desired ratio between paper space units and model space units. That's exactly why you need to resize the objects in your drawing when changing the scale. Setting dimension scale depends on how you lay out your drawing. So for an object that was originally meant to measure 10 feet, changing your units to inches would then require the object to actually measure 120 units (in this case, 120 inches, or 10 feet). If you did, in fact, change your units, you would eventually need the line to be measured in the number of your new units that match its measurement in the original units. However, the issue of scale forces a new wrinkle into this perfect unitless world. Attaching an image file into your AutoCAD drawing only inserts it. Whether you change your units to inches, meters, millimeters, angstroms, or parsecs, the line will continue to measure 10 units. The DELOBJ variable can be set to one of the following settings in the image below (. For example, a line drawn from the coordinates 0,0 to 0,10 in Decimal Feet will be 10 "units" long.
Convert to Architectural Scale: Type 12, and press Enter.ĪutoCAD is technically a "unitless" system. Convert to Engineering Scale: Type 1/12, and press Enter. The Command line will prompt you to Specify Scale Factor. The Command line will prompt you to Specify base point. Select the entirety of your drawing in Model space. The Command line will prompt you to Select objects. In Model Space, type SCALE in the Command line, and press Enter. This step will apply your new scale to all objects that are currently in your drawing – from linework to plants, irrigation equipment, hatches – everything! Step 1: Resize All Objects in Your Drawing The scale in each of these viewports represents a ratio of the paper size to the size of the model in the viewport.You need to convert an existing drawing from Engineering Scale to Architectural Scale, or from Architectural Scale to Engineering Scale.įor example, you may have reached an advanced stage in your drawing, only to have a client, supervisor, or design committee request that you submit your plan in a different scale.įortunately, you can convert your scale quickly in just a few steps. The second is the scale of the model itself, which is displayed in layout viewports. The first affects the overall layout of the drawing, which usually is scaled 1:1, based on the paper size. In a layout, you work with two scales. This scale represents a ratio of plotted units to the world-size units you used to draw the model. From model space, you can establish the scale in the Plot dialog box. The method used to set the plot scale depends on whether you plot model space or a layout: In this Autocad tutorial, I talk about drawing scale in Autocad.You need to draw your project in 'real scale' or '1:1' scale. Most final drawings are plotted at a precise scale. Add items, or delete the items you no longer want. When you plot the drawing, you either specify a precise scale or fit the image to the paper. If you've been wondering where to set the default values for the scale list in AutoCAD, look no further. For example, if your unit of measurement is millimeters, then every unit in your drawing represents a millimeter. Autocad drawing scale settings how to#
That is, you decide how to interpret the size of a unit (an inch, a millimeter, a meter) and draw on a 1:1 scale. Usually, you draw objects at their actual size.
