3D SCANNING AND REVERSE ENGINEERING SOLUTIONS

Leios


Fast and Reliable

Leios is an easy, fast, powerful and convenient software to switch from 3D scanning to CAD, which makes the processing of 3D scans and the editing of triangular meshes as easy as ever. 

With Leios it is possible to acquire data from any type of 3D scanner, to transform the point cloud into a mathematical NURBS model in an easy and fast way with a complete control of each phase and to analyze the results with powerful control tools.

Simplified Workflow

Leios, EGS’ proprietary reverse engineering software, offers numerous benefits such as optimized workflow: 

  • Scan Data
  • Mesh Elaboration
  • Mesh modeling
  • Reconstruction by Fitting
  • Surfacing and Inspection
  • Export
Scanner Integration

The direct integration between the best 3D scanners on the market and dedicated tools allow rapid optimization of point and mesh clouds and full support for textures and huge sets of raw data.  

One-click procedures optimize your point and mesh clouds for CAD processing and export your surfaces to IGES and STEP, with direct integration with most CAD solutions on the market.  

The new 2D sketc function allows direct editing of sections in arcs, lines, NURBS curves to create precise profiles. Leios2 is the perfect link between the scanner and the CAD of your choice.

Modeling Tools

Add

Add material to the mesh by controlling the area of influence and the density of added material. 

Remove

Remove material from the mesh by checking the influence area and weight of the chisel. 

Smooth

Smooth the entire mesh, a selection, or locally with a brush. 

Freeform deformation

Deform the mesh dynamically using an elliptical tool. 

Deformation by grid

Deform the mesh using control points ordered by grid, allowing precise deformation of the model. 

Edge optimization

Optimize and reconstruct the damaged edges on the mesh, priceless when working with mechanical parts.

FAQ Leios


How do I install the demo?

To install the demo of Leios just follow these few simple steps:

  1.  Download Leios 2 installer from the link on email received after submission;
  2.  During Leios 2 installation, choose “Keycode Protection” option when asked;
  3.  At the end of the installation procedure, click with the right mouse button on Leios icon on Desktop and select “Run as administrator”
  4.  Then navigate the main manu to the Preferences > License Registration command;
  5.  In the emerging window locate the “hardware fingerprint” information and send it to service.eng@egsolutions.com
  6. EGS support will send you the activation key.
What are “cloud points” and “.STL files”?

The points cloud is the resulting product from the scan: is a set of millions of points arranged and measured in a 3D environment. The scanner is able to capture millions of points in few seconds. The final scan can be viewed using special software that joins the points by forming millions of triangles connected: the .STL file.

What does “step by step” mean?

It is our philosophy because we have created Leios software step by step. It is always step by step that we keep developing and improving it to keep up with the times and the needs of users. This is the reason why the software is clear and easy to use and accompany the user during every stage of the process via a “step by step” path, the strength of our methology.

Is it possible to make measurements of the imported models?

Yes, it is possible. In the info menu you can find some measuring instruments (distance between points, angular measurements, volume, surface, etc.)

How is the texture managed in Leios?

You can import and display textured models.

You can not keep the texture if you make substantial changes on the mesh (i.e. extrusions, closed holes, etc.)

How can I select the model?

Check in the “select mode” (by default in on the left above the menu “management model”) if the correct selector [point cloud – mesh – surfaces] is turned on.

How can I zoom in/out the model?

To zoom in/out the model you need to use the mouse scroll wheel.

How can I shift the model?

To shift the model you need to:

Hold down the CTRL on your keyboard

Hold down the mouse scroll wheel

Move the mouse.

How can I rotate the model?

Hold down the CTRL on your keyboard

Hold down the left mouse button

Move the mouse.

Where should I insert the dongle with Leios license?

The dongle must be plugged into a USB 2.0 (black port).
