\pard\ltrpar\nowidctlpar\fi-360\li360\tx360 -\tab With the selected beam, column or brace the material physical properties of that object should be displayed in a dialog. \par
|
|
\pard\ltrpar\nowidctlpar\fi-360\li360 -\tab Present all material types and their sub types to the user and then change the material type of the selected beam to the one chosen by the user. \f1\par
|
|
\f0 -\tab With a selected concrete beam, column or brace change its unit weight to 145 P/ft3. Warn that this will change all instances of the elements that use this material.\f1\par
|
|
\pard\ltrpar\nowidctlpar\fi-360\li360\tx360\f0 -\tab Columns, Beams and Braces are represented as FamilyInstance objects within the Revit database.\f1\par

\pard\ltrpar\nowidctlpar\f0 Implementations:\f1\par
|
|
\pard\ltrpar\nowidctlpar\fi-360\li360\tx360\f0 -\tab The material element can be retrieved from a Family Instance object using the parameter named \ldblquote Column Material\rdblquote . This can be accessed in the manner shown in the sample code named Physical Prop. Other types of family instance will have a different name for this parameter which can be found using the Element Properties dialog.\par
|
|
\pard\ltrpar\nowidctlpar\fi-360\li360 -\tab All the available materials can be found by iterating through the document elements\f1 .\par
|
|
\f0 -\tab The Material Type can be retrieved by using the PHY_MATERIAL_PARAM_TYPE BuildInParameter\f1 .\par
|
|
\f0 -\tab Choices for a material type can be found by comparing all the Material\rquote s material type with the desired material type.\par
|
|
-\tab Material changes can be applied back to the element by using the \ldblquote Column Material\rdblquote property or similar property for other types mentioned above.\par
|
|
-\tab Physical properties of the material can be retrieved from the Material using various parameters\f1 .\par
|
|
\f0 -\tab The unit weight can be found from the Material by using the PHY_MATERIAL_PARAM_UNIT_WEIGHT BuildInParameter.\par

|
\pard\ltrpar\nowidctlpar\fi-360\li360 2.\tab Select a beam, a column or a brace; Load and run the MaterialProperties.dll\f1 .\f0\par
|
|
3.\tab Select a material type and sub material type, click the \ldblquote\ul A\ulnone pply\rdblquote button, then the selected beam, column or brace\rquote s material type will be changed.\par
|
|
4.\tab With a selected concrete beam, column or brace change its unit weight to 14.50 KN/m3 in metric project by clicking the \ldblquote Change Unit Weight\rdblquote button.\par
