What elements must be highlighted to effectively place structural columns in Revit?

To effectively place structural columns in Revit, highlighting grid lines is essential. Grid lines serve as a fundamental guide for positioning various structural elements within a model. When using grid lines, collinear alignment can be maintained, ensuring that the columns are placed accurately within the defined coordinate system of the structure.

Grid lines also offer a visual reference, allowing designers to organize and coordinate the placement of columns in relation to other structural and architectural elements. When columns are aligned with grid lines, it enhances consistency and helps in maintaining the overall geometric integrity of the building layout. By using grid lines effectively, you can ensure that the columns are positioned precisely where they are needed according to the design intentions and structural requirements.
