\pard\ltrpar\nowidctlpar\fi-420\li420\tx420\f2 -\tab\f0 The property Geometry can retrieve the geometric representation of the element. It will retrieve 3d representation of the element. Nothing will be returned for symbols, annotations or details. This involves extensive parsing or Revit's data structures, so try to minimize calls if performance is critical.\cf1\f1\par

\pard\ltrpar\nowidctlpar\fi-420\li420\tx420 1.\tab Draw an element first\par

\pard\ltrpar\nowidctlpar\fi-420\li420 2.\tab Then, select it.\par
|
|
3.\tab Run the external command. \par
|
|
4.\tab Expected result: It will show the element's geometry in a wireframe in a viewer.\par
|
|
\pard\ltrpar\nowidctlpar\qj Note: Some elements don\rquote t expose geometry, for example, curtain wall and dimension.\par
|
|
In case of a curtain wall, try selecting a whole wall by a window/box instead of a single pick. \par
|
|
So that internal components will be selected and its geometry will be able to be displayed.\par
