To make a dynamic frame and ensure that it is the same scale as the drawing, you can follow these steps:
Open AutoCAD 2020 and load the drawings you need to make a dynamic frame.
Enter the LAYOUT space, type the “LAYOUT” command, and then press Enter. Select an existing layout or create a new one.
Determine the scale of the drawing. For example, if the scale of the drawing is 1:100, it means that 1 unit of length represents the actual 100 units of length in the drawing.
Enter the “UNITS” command and press Enter to open the unit setup dialog. In the dialog box, select the correct linear unit, such as millimeter, inch, etc., and set the scale.
Enter the “PAPER” command and press Enter to enter the drawing space.
Draw the shape and size of the animation frame you want. You can use basic drawing commands such as lines, circles, and rectangles to create photo frames.
Ensure that frame objects are drawn to true scale. You can use a measurement tool, such as the “DIST” command, to check that the length of the line segment in the plot box matches the desired scale.
Create title bars and other necessary comments or labels.
Combine frame objects into a block as needed. Type the “BLOCK” command and press Enter. Select the frame object and set the appropriate block name.
Type the “LAYOUTREGENALL” command and press Enter to force a refresh of the views in the layout.
Return to the layout space, type the “-INSERT” command, and then press Enter. Select the box block created earlier and insert it into the layout.
Adjust the scale and position of the rack as necessary to make it consistent with the drawing scale.
Save drawings and apply them to other drawings as needed.
