Keith, What are you really trying to do? I will give you a few options. 1. Are you wanting to work in metric units? Create metric geometry and dimensions? If so, there are metric templates you can use. These will allow you to create a new draft file for metric drawing. The default units and dimension styles will be set up for metric if these are used. When you install the software, one of the options during installation is which templates to you want to use by default (Englich or Metric). The installation will take the appropriate template and copy to the 'Solid Edge 2D Drafting V19/Template' folder and name it 'normal.dft'. If you selected English, the default, this will be a English template. Any new draft file created using this template will be English. You can create a metric file by selecting one of the delivered metric templates. Click File-New and click on the More tab at the top of the dialog. you will see a list of more templates. Click on one of the metric templates, Normmet.dft, and click OK. This will create a metric file. 2. Do you want to draw in English and create metric dimensions? There are a couple of things you can do. There are dimension styles delivered that allow English or metric dimension values. Draw a horizontal line. Click one of the dimension commands. On the dimension ribbon bar, you can change which style to use on the dimension with the first combo box to the left. Set it to ANSI. Place the dimension on the line. It will display an inch value. Change the style to ISO. Place another dimension on the line. It will display a metric value. The dimensions will look different because of the way options are set in the two styles. You can also change the style of an existing dimension by clicking on the dimension and changing the style in the same combo box. 3. Do you want to display both English and metric values on the diemnsions? You can do this by enabling dual unit display in the dimension style. Click Format-Style. With the proper style selected in the list, click the 'Modify' button. Click on the Secondary Units tab in the Modify Dimension Style dialog. Click the 'Dual unit display' check box. Click 'OK' and then 'Close'. your dimensions created with the ANSI style will display both inch and metric values. Go back and look at the things you can change in the dimension style that control how they display. If you want to make changes to styles that will be there for each new file you create, create your own template. Create a new draft file and make the changes to the styles. Save the file and move it to the 'Solid Edge 2D Drafting V19/Template' folder. Now when you create a new draft file it will show up in the File-New dialog. 4. Do you only want to display one dimension with different units? Right mouse click on the dimension you want to change. Click on 'Properties' at the bottom of the context menu. In the dimension properties dialog click on the Units tab. Change the Units. You may want to change the roundoff also. Hope this helps. Rick B.
