When purging a model in SketchUp or uploading it to the 3D Warehouse, unused materials will be removed. If your model contains a Dynamic Component, though, you may also lose textures in "Choose Options" or "OnClick" attributes. To avoid losing these textures, you'll need to embed them into the Dynamic Component:

OnClick FunctionsFunctionDescriptionExample(s)ALERT("message")The ALERT function displays the value of the message in an alert box.Example:  =ALERT("You Clicked Me!")

Logical Functions (for math-related use)FunctionDescriptionExample(s)AND(logicalValue1, logicalValue2, ...logicalValueN)The AND function returns TRUE if all arguments are TRUE. If any element is FALSE, this function returns the FALSE value.

Trig FunctionsFunctionDescriptionExample(s)ACOS(number)The ACOS function returns the inverse cosine of the number in degrees.View SketchUp Example<

This is a Pro only feature.The following HTML tags are supported within a Dynamic Component's Description and Summary fields:<a><b><i><u><strong><em><p><br><ol><ul><li><font>Any tag or version of a tag that is not in this list will be ignored. The following additional rules also apply:

Following is a list of all operators supported in dynamic component formulas.+ (add)- (subtract)* (multiply)/ (divide)< (less than)> (greater than)<= (less than or equal to)>= (greater than or equal to)= (equal)() (parentheses)<> (not equal to)

Following is a list of all functions supported within your dynamic components. Many of these functions are identical to functions found in spreadsheet applications such as the spreadsheet application that is a part of Google Docs. Math functions The following functions are for math-related use: ABS(number) The ABS function returns the absolute value of number.

This is a Pro only feature.Following is a list of all predefined attributes for use in creating your dynamic components.X, Y, ZThe X, Y, and Z attributes contain the value for the component's X (red), Y (green), or Z (blue) coordinate.LenX, LenY, LenZThe LenX, LenY, and LenZ attributes contain the length of the component in the X (red), Y (green), or Z (blue) direction.RotX, RotY, RotZThe RotX, RotY, and RotZ attributes contain the rotation about the X, Y, or Z axis, in degrees.
