It offers superior performance and the interface is better developed. Mirrored entities in a sketch are an instrumental part of establishing design intent. Two methods of mirroring items in a sketch are discussed here along with a method to make entities work as if they have been mirrored when in fact they were manually drawn. Mirror Entities Mirror Entities works by selecting the entities that you want to mirror along with a single centerline and clicking the Mirror Entities button on the Sketch toolbar. It is a simple and effective tool that you can use on existing geometry. This method is the fastest way to use the tool but there are other methods. You can preselect or post select using a dialog box to select the mirror line which does not need to be a centerline. One feature of Mirror Entities may sometimes cause unexpected results. For example in some situations Mirror Entities will mirror a line or an arc and merge the new element with the old one across the centerline. This happens in situations where the mirror and the original form a single line or a single arc. SolidWorks may delete certain relations and dimensions in these situations. Dynamic Mirror As the name suggests Dynamic Mirror mirrors sketch entities as they are created. You can activate it by selecting a centerline and clicking the button on the Sketch toolbar. Dynamic Mirror is not on the toolbar by default you need to select Tools C Customize C Commands to add it to the toolbar. You can also access Dynamic Mirror through the menus at Tools C Sketch Tools C Dynamic Mirror. When you activate this function the centerline displays with hatch marks on the ends and remains active until you turn it off or exit the sketch. .
