About this asset

This parametric Revit detail component provides a precise representation of an elongated slotted hole for technical documentation. The component is a 2D drafting element designed for use in Revit plan or section views to indicate slotted hole configurations. It features adjustable parameters for both hole length and hole diameter, allowing for rapid adaptation to various fastening or clearance requirements. The geometry is clean, consisting of two parallel lines connected by semi-circular arcs, and is defined by reference planes to ensure consistent placement and alignment within a project environment. This family serves as a lightweight, efficient tool for detailing connections or penetrations without the overhead of complex 3D geometry.

The download is a 297 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Users can load this family into a project and place it directly into drafting views or onto sheets as a detail component. The dimensions are controlled via type or instance parameters, allowing the user to modify the slot size dynamically within the properties palette. It is best used for standardising documentation across a set of construction drawings, ensuring that all slotted hole representations maintain a uniform graphic style throughout the project's technical documentation and site-specific installation details.

This detail component is essential for architects and structural engineers working on steel connections, mechanical equipment mounting, or custom joinery details. It is particularly useful when specifying adjustable fixing points in shop drawings or assembly instructions. Professionals searching for this asset will typically be creating construction documentation in Revit and require a quick, reliable way to represent mounting slots for bolts or service penetrations in steel plates, timber frames, or bespoke metalwork components throughout various project stages.
