Tip: Creating a drawing template with Fields in Bricscad

For those of you that are not familiar with fields, and how one might use them effectively . I’d like to show an example using Fields to create a more powerful, simpler to use drawing template. The main goal here, is to have as much drawing text as possible, be editable from a single source Ergo, reduce mistakes.

Basically a Field is a text property that can be inserted into Block Attributes, Leaders, Mtext or Table. A Field can be associated with a value, variable or expression, such as a lisp expression, system variable, an Entity’s property, or as in this example, a custom drawing property value.
For my template, I have created a new drawing using one of the standard templates that ship with Bricscad. I’ve inserted an existing title block with attributes, that I will be adding Fields to. Using the DWGPROPS command to show the Drawing properties dialog and under the custom properties tab, Click the add button to add in new values. I’ll add in a few commonly used text items, typical for a title block.clip_image002After I’ve added a few Custom Property keys, I’ll use the attribute editor to assign the corresponding fields. Note the values are still empty, so the fields will evaluate as empty or “—-“, we will fill these out later when we start our project drawing . While in the attribute editor, right click and choose “Insert Field” from the context menu.

Once the Field dialog is open, you can choose the key to associate the field text with.

I’ve added a field to each attribute in my title block, and assigned the corresponding field. For the page number attribute, I ‘ve assigned the system variable “CTAB”, so this field will match the paper space tab name. Now I will never need fill out this page number again : ) At this point I’ll save the my .DWG as a template, in the templates folder.

So now I am ready to start a new project using my new template. I’m a command line guy, so I’ll run the “New” command and choose my new template. Before I start drawing anything, I’ll want to run the DWGPROPS command and fill out the Values for the Custom Property keys I setup in the template.

Now, my title block is all filled out and evaluated, the text will be the same on each new paper space tab, and if I need to make a change, I only need to do it in one place. Really, this is only the tip of the iceberg to what you can do with Fields, so have a good look at them to see how they can make you more productive.
