A guide to the downloadable CAD and STEP library, organized by application, so you can pull the right model and detail for sheet piling, seawalls, abutments, MSE walls, channels, and box culverts and drop it straight into your drawings.
Detailing a weep hole filter is faster when you start from verified geometry. The Engineering Hub hosts downloadable CAD and STEP files for every JET Filter™ and GEOJET model, plus application-specific installation guides and detail drawings. This guide explains the file formats, walks through the application library, and offers a few tips for getting the units into your CAD and BIM environment cleanly.
Every model in the library ships as verified, dimensioned geometry ready for your drawings.
Which File Format to Use
Each model is available in four download types. Two are drawings and two are data, and which you reach for depends on whether you are detailing in 2D or modeling in 3D.
The Four Download Types
CAD Files. 2D drawing geometry for placement into plan, section, and detail sheets.
STEP Files. 3D solid models for BIM coordination and clash detection, scaled to the real unit.
Cut Sheets. Dimensioned reference in imperial and metric for callouts and submittals.
Product Specs. Tested flow, material grade, surface area, and intervals to support the detail.
STEP files drop the unit into your 3D model at the correct scale for coordination and clash detection.
The Application Detail Library
Beyond per-model files, the Hub includes installation guides and detail drawings organized by structure type. Start from the one that matches your project and adapt the detail to your wall section.
Sheet Piling. Installing filters in steel and vinyl sheet pile walls, including combined concrete and sheet piling applications.
Concrete Seawalls & Bulkheads. Step-by-step installation for concrete coastal structures.
Bridge Abutments & Wing Walls. Installation details for bridge infrastructure applications.
MSE Retaining Walls. Technical guidance for mechanically stabilized earth wall applications.
Trapezoidal Concrete Lined Channels. Installation procedures for lined drainage channels.
Box Culverts. Installation procedures for box culvert drainage applications.
French Drain Details. Behind highway approach ramps and retaining walls, sheet piling waterfront walls, and concrete coastal seawalls.
Pick the Model Before You Pull the File
The library covers all 13 models in sizes from 2.5 to 6 inches, with check valve (CVLV) versions for tidal and backflow conditions. Size to your design flow, then download the matching CAD and STEP files. GEOJET models, engineered for hydrocarbon capture, share the same housings and footprints as their JET Filter™ counterparts.
| Size | Standard Model | Check Valve Model | Typical Use |
|---|---|---|---|
| 2.5″ | JF2.5ABS | – | Protected freshwater, light duty |
| 3″ | JF3SS / GEO3SS | JF3SSCVLV / GEO3SSCVLV | Standard walls, moderate flow |
| 4″ | JF4SS / GEO4SS | JF4SSCVLV / GEO4SSCVLV | Higher flow, DOT and marine |
| 6″ | JF6SS / GEO6SS | JF6SSCVLV / GEO6SSCVLV | Highest flow, fewer penetrations |
All stainless models use 316L-grade housing with a 100+ year service life. For tested flow data by model and condition, see the Complete Weep Hole Specification Reference Guide.
Getting the Files Into Your Model Cleanly
Confirm units on import. STEP files carry their own units; verify scale against the cut sheet dimensions after importing.
Place at the penetration. Use the STEP solid to check fit against reinforcing, embeds, and wall thickness before the detail is fixed.
Reference the cut sheet in callouts. Keep the 2D CAD detail tied to the model number and the dimensioned cut sheet so the contractor orders the right unit.
Carry the spec into the submittal. Pair the detail with the product spec and compliance documentation from the Hub for a complete package.
Pull the Files for Your Next Detail
CAD files, STEP models, application detail guides, and cut sheets for all 13 models are available through the Engineering Hub at no cost.
