Using Expand

This Tech Tip explains how to use the Expand function.

Adding an Additional Layer The Expand function allows you to automatically produce a detailed view within a box or circle. It can also be used as a "cut and paste" function if magnification is set to 1.

This function will give you the option to save the detailed view onto a separate layer. It is advisable that you do this, because otherwise it is easy to accidentally change the magnification of your drawing. Ensure you have created a layer to save the detailed view to before using Expand.

The first step is to create/add the layer for the expanded view.

Settings Menu › Layer Settings


A new layer is added.


Click on OK to continue.

Creating the Expanded View
Tools Menu › Expand


If you want the detailed view to appear inside a box, click on the YES button.

If you want the detailed view to appear inside a circle, click on the NO button.



If you would like the box or circle to be drawn around the detailed view, click on the YES button.


Otherwise, click on the NO button.


Detailed view in a box


Position the cursor at one corner of the area you want a detail of and press [Enter] or click. To position the cursor exactly onto a specific point, the various snaps modes can be used.


Position the cursor at a diagonally opposite corner of the area you want a detail of and press [Enter] or click.

Detailed view in a circle


Position the cursor at the centre of the area you want a detail of and press [Enter] or click.


Position the cursor at a position on the expand circle’s circumference and press [Enter] or click.


Type the magnification of the detailed view and select or press [Enter]


A box representing the size of the detailed view appears. Move this to a suitable position on the screen and press [Enter] or click. The detailed view is drawn.


This question is only asked if you have chosen to draw an expand circle rather than a box, and if you have drawn this circle around the detailed view. If you want to join the two circles with an arrow, click on the YES button, otherwise click on the NO button.

A dialog box with the heading Magnified Layer appears. Choose a layer for the detailed view to be copied into by clicking on the appropriate layer in the dialog box or by typing in the corresponding letter.


Enter new magnification for layer 'newlayer'


Anything that you subsequently draw onto the layer that the detailed view is on will have the magnification that you give here. For example, if the drawing scale is 1:1, and you give a magnification of 2, anything else that you draw on this layer will be drawn at a scale of 1:0.5.

If you have placed the detailed view onto the same layer as the rest of your drawing, it is important that you type a magnification of 1 so that anything else you draw on the layer is not drawn at the wrong scale.
