spGate is the tool that provides powerful support for the process connector between CAD/CAM/CAE/CAT.

Not only can spGate convert a variety of 3D CAD data, spGate can run error check, make quality improvement such as CAD data modification to suite the process, and thereby spGate strongly supports the process cooperation.


What's new in spGate 2019.1

Note: This movie has sound.

Die & Mold

Check the existence of undercut in the specified direction.
The direction without undercut can also be determined automatically.

Check for surface deformation by indicating the direction.
You can also set the curvature range of CAD model automatically.

As a measure to cope with incomplete cutting of concave fillets, two features to modify concave fillet have been introduced.
1. Offset
2. Deform Fillet

Move the center of the geometry sheet in the Z+ direction and modify the entire shape of the model.
Thereby the pressure from the press die is homogenized.

For surface group models that are disconnected and not solid will be automatically set the outer to the front side.
Please use “Auto Correct Face Direction” just before CG rendering and pre-processing of inspection.


Simple Fillets and Corner Fillets can be removed automatically by specifying the radius value.


It is possible to simplify by removing in stages the complicated Fillet shape which is difficult to remove automatically.
Unlike the CAD system, there is no problem even if gaps and holes are created during the work process.


The chamfered shape part (cone, plane) can be recognized and removed automatically by specifying the angle.


Unnecessary Boss shape and Cutout can be removed by specifying the range.


Enables the multiple plane shapes such as CAE models to unite automatically. A significant reduction in the number of surfaces is possible.


It is a function to instantaneously remove the hidden (invisible) faces seen from any direction.
Even with data of about 10,000 faces, it is possible to remove hidden faces in a few seconds.
By significantly reducing the size of CAD data, it is possible to shorten the rendering time of models for CG and ensure the confidentiality of data to be taken outside the company.

It is a function to unfold outlines of the 3D surfaces to 2D.
Enable to use in a wide variety of fields including graphic decal design to be stuck on the cowl of a motorcycle and logo seal production on 3-dimensional surfaces.
It is also enable to suppress the expansion and contraction points or to simulate the final state of expansion and contraction by gradation display.
Outline data unfolded to 2D can be exported with IGES or DXF file.


Import polygon mesh data (STL) and surface data (IGES, STEP, etc.) at the same time and divide polygon mesh data with the surface.

Error Checking & Healing

With the automatic healing function, models with minor error are automatically corrected.
If the correction method is not uniquely determined and the judgement of the operator is necessary, the error part is detected using the check function and it is corrected manually.

Highly accurate examination of interference and collision between multiple parts.


“Fillet radius”, “Draft angle”, “Hole Diameter”, “Plane height”, “Plate thickness” and “Primitive surface” in the CAD model will be recognized instantly, and will be color-coded automatically.

Import the CAD models before and after design change and change of shape (hole position change, Boss position change, Fillet radius value change, with or without draft angle, etc.) can be confirmed in detail by gradation display.

Verified according by PDQ (Product Data Quality: Model Data Quality) Guidelines established by JAMA (Japan Automobile Manufacturers Association) and JAPIA (Japan Auto Parts Industries Association)

There are also spGate original error check items. Various error check patterns can be constructed and use them separately.


Minor errors can be corrected automatically.


Severe errors are fixed manually.
When modification is impossible, it is possible to remove an error surface and create new tangent continuous surface connect to adjacent surfaces.

3D Data Translation


spGate standardly equips 3D Native Files of CATIA V5, NX, Creo (Pro/E), Alias, Rhinoceros as well as IGES, JAMA-IS, STEP, Parasolid, ACIS, STL and OBJ.
spGate is a multi-translator that corresponds to most three-dimensional CAD data circulating in the world.
