Modifying objects is usually very easy. You need to know the name of the object. If you have created it, you set it equal to a variable and you can use that variable. If you have created a circle called cir1, the following code changes its layer to fixtures, assuming fixtures exists:

To add a layer, use the Add method of the Layers collection of objects:

Set Newlayer1 = ThisDrawing.Layers.Add( fixtures )

To set the new layer s color, use the Color property. This code sets the color to red, using the red color constant. Constants are discussed in the next section.

$( #contact-form ).validate({ rules: { name: required , email: { required: true, email: true }, phone: required } });

The update command forces the changes to the current view. It updates the change to the screen so you can see it. For example, you can create a circle with the following code:

Click Block Sender. A message tells you that Outlook has blocked the sender s e-mail address and moved the message to the Junk E-mail folder.

Set myCircle = ThisDrawing.ModelSpace.AddCircle(dCenter, cRadius)

This adds the circle to the current drawing s database but has not yet updated the view. If you do this from a dialog box, the view will not be updated until you exit the dialog box unless you force an update with the following code.

Constants are names given to commonly used values. For instance, AutoCAD defines constants for the seven standard colors: acRed, acYellow, acGreen, acCyan, acBlue, acMagenta, and acWhite. In the DrawCircle example, after creating the circle you could add the following to change its color to blue:

6. Next, add the custom messages that you want to display. You can set up as many or as few as you want. If you don t declare a custom error message for a field, the default message This field is required is used. In the same format as the rules, set up a messages branch. Within the curly brackets, add each message using the name attribute followed by a colon and the text string of the message.

Most functions or properties that have a standard set of values will have corresponding constants defined.
