Definition


In KE-chain, a property defines a characteristic of a part. As with parts, properties can be split into two categories: property models, which are located under part models and property instances, which are used under part instances. For example, a part model "table top" could have a property model called "material". If a specific part instance would be instantiated from that part model, say Glasholm table top, the "material" property also exist under the part instance.

The following applies to properties:

  • A part model can contain an arbitrary number of properties
  • Properties exist in different types
  • Properties defined under a part model will be replicated under every part instance created based on that respective part model.
  • All property models have a default value, which can be left empty or can be filled in. Any filled in default value will be translated to the values of the property instances, but the property instance value can be changed anytime afterwards. If the default value is left empty, then the property instance will be instantiated with an empty value as well.
  • All property models have property validators. These are used to impose certain requirements on the property values to be filled in. Whenever such a property validator is used, the user will be notified that the property value is not respecting some of the requirements defined in the validator. The most common validator is the 'required value' validator, which notifies the user that the property value must be filled in. See below examples of how properties with such validators look inside KE-chain.

Panel

All properties have the following settable fields:

  • Display name
  • Description
  • Type
  • Value
  • Required property value validator

The display name, description and type must be specified on the property model and the property instances created based on them will copy the fields. Any subsequent edit of the name or description must occur on the property model. The type cannot be changed after creation.

As mentioned above, the default value can be specified on the property model and the property instances will copy that value on creation. The value of each individual property instance can be changed separately and is not linked to the property model default value after creation.

The integer and decimal propertiesalso have an unit field and a specific numeric field validator, where a minimum and maximum value can be set, as well as a stepsize. They also allow for the values to be displayed using thousand separators, which take into account the language the user is using and display the numbers accordingly (e.g. 123,456.78 for English language and 123.456,78 for Dutch).

The decimal property also has a display field, which can be used to either display the value as it is, restrict to only a certain number of decimal places, or present only a particular number of significant digits.

The single line text and multi line text also have a regex (regular expression) field, which is used to restrict the text inside to a certain pattern. The 2 format options currently are email, which, as the name implies, restricts the text to be in the standard email format, and custom, which the user can edit itself as it pleases. This custom feature is best handled by users with some minimum knowledge in regular expressions.

The link property allows the user to specify whether he wants to have the link open in the current tab or in a new one through a field called link target.

The single select list properties also have a list of items field, used to add the options that the user can select from. These options can also be displayed as either checkboxes, dropdown list or buttons.

The part reference properties need to be connected to a part model through the selected part model field. It also has a single reference validator, which restricts the property value to reference just a single part.

The attachment property allows the specification of a file extension as well as a maximum size for files that are to be uploaded to that property.


Types of properties



The following table shows the property types available. Each property type has a number of configurable options, of which some are optional and some are specific to the type of property.

The overview below shows all property types available in Property, and their specific details, if any.
