Cimatron E11 ^new^ May 2026

Cimatron E11 is a bit older (released around 2013), but it is still widely used, especially for mold & die and 3-axis milling. A "useful post" for E11 depends heavily on your machine + controller (Fanuc, Heidenhain, Siemens, Mazak, etc.) and machine type (mill, mill-turn, wire EDM).

Here’s a breakdown of how to get a useful post for Cimatron E11, what works well, and common pitfalls. cimatron e11

Cimatron E11: Quick Reference & Workflow Guide

Step 2: Creating Features

Extrude: Select a sketch profile. Define direction and height.
Revolve: Select sketch profile + an axis line.
Round/Fillet: Select edges. In E11, you can toggle between "Constant Radius" and "Variable Radius" in the wizard.
Draft: Essential for mold makers. Tilt faces for extraction.

Part 7: The Legacy – Is Cimatron E11 still relevant?

The short answer is: Yes, for specific niches. Cimatron E11 is a bit older (released around

Used Machinery Market: Many shops purchase a used CNC machine (like a 1999 Mazak or a 2005 Fadal) and need a CAM system that understands the machine's limitations. E11 fits perfectly here.
Repair Shops: If you are only modifying mold inserts or repairing damaged cavities, you don't need generative AI design. You need reliable surface milling. E11 provides that without expensive annual maintenance fees.
Learning: Because Cimatron E11 is widely available on the second-hand market (licenses often sell for $500-$1500 on forums), it is an excellent tool for a machining student to learn the logic of 3D CAM without cloud subscriptions.

However, for high-efficiency shops running 5-axis simultaneous, robotic automation, or complex lattice structures, modern alternatives (Cimatron 15/16, NX CAM, or Mastercam 2025) are objectively superior due to processing speed and collision avoidance. Extrude: Select a sketch profile

1. The Hybrid Modeling Environment

Unlike parametric-only tools (like SolidWorks), E11 uses a hybrid kernel. It allows users to work with solids, surfaces, and wireframes in the same environment without switching modes. This is critical for mold repair where an engineer might need to convert an imported STEP file (surfaces) into a solid to add a draft angle.

Direct Editing: E11 introduced advanced direct editing tools for modifying imported geometries without a history tree.
Parasolid Kernel: Full compatibility with Siemens NX and SolidWorks via native .x_t files.

The "Cons" (Challenges of using it today)

No Support: 3D Systems has long since ended support for E11. No bug fixes, no driver updates for Windows 11.
File Compatibility: Reading STEP files from modern 2025 CAD packages (SolidWorks 2024, Catia V6) can result in "dumb solids" with missing faces. You often need to export as older IGES or Parasolid V24.
Multithreading Limitations: Modern computers have 32 cores. Cimatron E11 was designed for dual-core processors. Toolpath calculations for complex 3D finishing will only use 1 or 2 cores, making it slower than modern versions on the same hardware.
