Overview

This tool may be used in the Drawing Editor or in Modeling to scale a reference drawing. In Modeling , this tool is especially useful for rescaling linked PDF plans.

In Modeling ...

  • You can scale any drawing that you can " Add " in the Reference Drawing Tools window. (That is, detail , job standard detail , reference drawing or 2D erection view drawings). This includes reference drawings created when you " Link " to external files.
  • When you scale a reference drawing, the actual drawing is rescaled. Use the ruler to scale part of the drawing in Modeling , then use the ruler to measure the same part of the reference drawing in the Drawing Editor -- you'll find that it is the same length in both programs.

In the Drawing Editor ...

  • You can only scale reference drawings .
  • You cannot, however, scale reference drawings that link to external files, such as those created when you " Link " to external files in Modeling .

Drawing Scaling Example :

Before using this tool in Modeling :

Optional: Verify that the reference point for the drawing that you want to scale is in the desired location

Before using this tool in the Drawing Editor :

Recommended: Unshorten if you are edting a shortened reference drawing.

1 . In Modeling , invoke Scale Drawing Single Axis . In the Drawing Editor , invoke Scale Drawing Single Axis .

2 . Left-click ( Draw ) to select the first point on the X- and Y- axes that you want to locate -- in this case, the bottom left corner of a drawing title block.

3 . Left-click ( Draw ) to select the second point on the X- and Y- axes that you want to locate -- in this case, the opposite corner of the title block that you selected in step 2.

4 . Check " Maintain Aspect Ratio " and enter a " New Measured Distance (X) ." The " New Measured Distance (Y) " field is automatically updated. (Here, ' 140-0 ' is the entered to " New ... Distance (X) ." 35:23 equals 140:92, so ' 92-0 ' is automatically entered.)

Tip: To resize the reference drawing to an exact scale, select points whose distance apart in the original drawing along the X- and Y-axes is known. In the example above, you select the corners of a title block border. That way, when you enter the " New Measured Distance (X) ," you can enter ' 140-0 ' (2'-11" × 48) to rescale the drawing to full size along it's X-axis, and enter ' 92-0 ' (1'-11" × 48) to the " New Measured Distance (Y) " to rescale the drawing to full size along it's Y-axis.

Step-by-step instructions (also see the example ) :

To accurately enter distances on a reference drawing that has been shortened, you may have to first Unshorten . The following instructions assume that you are using a 3-button mouse.

1 (optional) . Before using this tool in Modeling :

Verify that the reference point for the drawing that you want to scale is in the desired location, because the drawing will be scaled in reference to that insertion point . You can do this in Modeling by clicking the " Set Reference Point ' button on the Reference Drawing Tools window, or in the Drawing Editor by doing a Verify Reference Point . You can, however, set the reference point later, as well as press the " Move " button to relocate the drawing.

 
Before : The drawing is linked, and added to the drawing without being scaled.
  		  After : The drawing is scaled, but the reference point (shown green here) remains in the same location in the model.

2 . Invoke Scale Drawing Single Axis using any one (1) of the following methods:

Drawing Editor : Click the Scale Drawing Single Axis icon. The icon can be taken from the group named ' Tools '. and placed on a toolbar (classic) or the ribbon (lightning).

Modeling : Click the Reference Drawing Tools icon. The icon can be taken from the group named ' Model '. Highlight the desired drawing in the list, then press the Scale Drawing Single Axis button.

Drawing Editor & Modeling : Scale Drawing Single Axis ( Drawing Editor ) or Reference Drawing Tools (Modeling) can also be configured to be invoked using a keyboard shortcut , the context menu , or a mode . For the lightning interface, this configuration is done using Customize Interface .

3 . Draw - Move - Return mouse bindings become active along with various Locate options. The status line prompts you to " Select first point for x axis ." You will also select the first point along the Y-axis.

bindings

3a (optional) : Select the Locate icon that you want (if it's not selected already).

3b : Place the mouse pointer ( ) so that the point location target ( ) snaps to the first point on the X-axis that you want to locate, then left-click ( Draw ).

Note: It doesn't matter whether the first point that you select is the leftmost or rightmost X-axis point, or the topmost or bottommost Y-axis point -- the " Measured Distance (X) " and the " Measured Distance (Y) " will always be positive.

4 . Draw - Move - Return mouse bindings continue to be active. The status line prompts you to " Select second point for x axis ." As in step 3, you will also select the second point along the Y-axis.

bindings

4a (optional) : Select the Locate icon that you want (if it's not selected already).

4b : Place the mouse pointer ( ) so that the point location target ( ) snaps to the second point on the X-axis that you want to locate, then left-click ( Draw ).

Note: It doesn't matter whether the point you enter is exactly parallel to the X- or the Y-axis -- only the horizontal distance between the two points along the X-axis is entered as the " Measured Distance (X) ," and only the vertical distance between the two points along the Y-axis is entered as the " Measured Distance (Y) ."

5 . The Adjust Drawing Scale window opens. The Scale Drawing Single Axis tool reports absolute value of the difference between the X coordinates of the points located in steps 3 and 4 and reports that distance (in the primary dimension " Units ") on the " Measured Distance (X) " field of the Distance Ruler window. Similarly, it reports the difference between the Y coordinates of those points on the " Measured Distance (Y) " field.

5a (optional) : Adjust the " New Measured Distance (X) " to rescale the drawing, so that any part of the drawing that was previously the meaured distance along its X-axis is scaled to the distance you enter.

5b (optional) : Adjust the " New Measured Distance (Y) " to rescale the drawing, so that any part of the drawing that was previously the meaured distance along its Y-axis is scaled to the distance you enter.

Alternative : If the drawing is proportional before you scale it -- that is, if a unit of measurement in the X-axis already equals a unit in the Y-axis in the drawing -- you may check " Maintain Aspect Ratio " to "lock" the two fields together so that the X- and Y-axis values remain proportional. When checked, if you make an entry to a " New Measured Distance... " field, the other " New Measured Distance... " field is updated automatically.

Note: If you skip both steps (5a and 5b), the drawing will not be scaled.

6 . To close the Adjust Drawing Scale window, press " OK " or " Cancel ."

"OK" (or the Enter key) closes this window and scales the drawing about its reference point, if you adjusted the " New Measured Distance (X) " or " ...(Y) " entries in step 5.

"Cancel" (or the Esc key) closes this window without scaling the drawing.

Note: In Modeling , you can " Move " the reference drawing to better coordinate the drawing with the 3D model.

------ Current Measurements ------

Measured Distance (X): This read-only information field reports the absolute value of the difference between the X coordinates of the points that you select. The global coordinate system is used to calculate the distance (in the primary dimension " Units " or other units ) between the points.

Measured Distance (Y): This read-only information field reports the absolute value of the difference between the Y coordinates of the points that you select. The global coordinate system is used to calculate the distance (in the primary dimension " Units " or other units ) between the points.

------ New Scaling Dimension ------

New Measured Distance (X): The distance (in the primary dimension " Units " or other units ) to which the " Measured Distance (X) " will be scaled along the X-axis of the global coordinate system when you press " OK ."

New Measured Distance (Y): The distance (in the primary dimension " Units " or other units ) to which the " Measured Distance (Y) " will be scaled along the Y-axis of the global coordinate system when you press " OK ."

Maintain Aspect Ratio: or . This ensures that the drawing remains proportional when you make entries to the " New Measured Distance (X) " and " New Measured Distance (Y) " fields.

If this box is checked ( ), when you enter a new value into a " New Measured Distance... " field, the other " New Measured Distance... " field is updated automatically, so that their X- and Y-axis values remain proportional.

If this box is not checked ( ), when you enter a new value into a " New Measured Distance... " field, the other " New Measured Distance... " field is not automatically updated.
