3D CAD Modelling Services in Saudi Arabia
Parametric 3D models of equipment, assemblies, and plant layouts — designed for fabrication, analysis, and clash detection workflows in KSA.
SLETEC Engineering delivers professional 3D CAD modelling services for mechanical equipment, structural assemblies, skid packages, and plant layout reviews across Saudi Arabia. Using SolidWorks and Autodesk Inventor, our engineers build accurate parametric models that support downstream activities including FEA analysis, fabrication drawing extraction, interference checking, and procurement documentation.
Our 3D modelling workflow begins with a thorough review of reference inputs — 2D drawings, sketches, specifications, or site survey data — and progresses through concept modelling, detailed parametric modelling, assembly validation, and drawing extraction. We model individual parts, multi-component assemblies, and full equipment skids with the same discipline, ensuring every model meets manufacturing tolerances and design intent.
For brownfield and existing plant projects, SLETEC can produce 3D models from site measurements, laser scan point cloud data, or legacy drawings, enabling clients to build accurate digital representations of their facilities for modification planning, clash detection, and maintenance studies. All 3D models are delivered in native CAD formats plus neutral STEP and IGES exports for compatibility with client engineering environments.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Frequently Asked Questions
What 3D CAD software does SLETEC use for modelling in Saudi Arabia?
SLETEC primarily uses SolidWorks and Autodesk Inventor for parametric 3D modelling of equipment and mechanical assemblies. For plant layout and facility modelling, we work with AutoCAD 3D and can support point cloud-to-model workflows for brownfield sites.
Can SLETEC create 3D models from 2D drawings or sketches?
Yes. SLETEC routinely converts existing 2D drawings, sketches, or hand-drawn concepts into accurate 3D parametric models in SolidWorks or Inventor. These models can then be used to generate updated 2D drawings, perform FEA analysis, or support fabrication.
Does SLETEC provide 3D models for clash detection in plant design?
SLETEC can produce 3D equipment and structural models suitable for integration into plant design environments for clash detection and spatial coordination. We can deliver models in STEP, IGES, or native SolidWorks formats compatible with Navisworks and similar clash detection tools.
What deliverables come with a 3D CAD modelling project?
A typical 3D CAD modelling project from SLETEC includes the native 3D model files (SolidWorks SLDPRT/SLDASM or Inventor IPT/IAM), neutral format exports (STEP, IGES, STL), extracted 2D engineering drawings, and a Bill of Materials where applicable.
