PRODUCTS WE OFFER

AlarvyCAD - 3D CAD Modeler for Turned and Sheet Metal Parts - Price: $200

AlarvyCAD is India's first 3D CAD modeling software. It is a simple 3D CAD modeler with two modules.

  • Turn module - for creating turned parts
  • Sheet Metal module - for creating sheet metal parts

Unlike generic CAD modelers, which are suitable for creating any type of parts, AlarvyCAD is a specific CAD modeler with features specific to create turned parts and sheet metal parts. This reduces lot of unwanted functionalities and makes the user interface very simple. AlarvyCAD helps you to create detailed 3D models faster than any other modeler. AlarvyCAD reduces number of clicks extensively to create models with

  • Auto-dimensioning
  • Auto-constraints
  • Auto-expanding grid
  • Auto-view change for sketching
  • Sketch self intersecton checks
  • Smart checks for feature creation


Demo Video of ALARVY Beta

While creating features, AlarvyCAD automatically changes view for sketching. It applies auto-constraints like horizontal constraint, vertical constraint and grid snap to make sketching faster. Grid expands automatically when sketch points are outside grid limits. While sketching it auto-checks for sketch self-intersecton and invalid sketching profiles. It auto-dimensions the features thereby improving productivity to a great extent.

AlarvyCAD files are saved in simple json format and is an open file format based on feature data rather than B-Rep data. This makes AlarvyCAD files smart rather than dumb 3D models. This helps to facilitate easy integration with any CAM software and apply CNC routines specific to features. Detailed documentation of AlarvyCAD file format is available in help. The 3D models generated in AlarvyCAD can be saved in other formats such as STEP, STL(ASCII), STL(Binary), OBJ, GLTF, GLB files can also be saved.

OEM license for Machine tool manufactures and CAM ISVs are available.

Automobile Companies can showcase their products along with details of accessories and preferred vendors.


ALARVY 3D Part Recognizer

Alarvy 3D Part Recognizer is an AI/ML(Artificial Intelligence/Machine Learning) engine to automatically recognize parts in manufacturing using machine vision within milliseconds, which can be used for various downstream activities like

  • Assembly operations where multiple parts are to be recognized automatically and assembled.
  • Automatic part recognition and sorting for packaging, inspection, assembly, etc.
  • Automatic part segregation after 3D printing multiple parts.

Part recognition outputs by Alarvy 3D Part Recognizer

Alarvy 3D Part Recognizer is built using Convolutional Neural Network. The application is developed using python with OpenCV, PIL, Keras using TensorFlow as backend, ThreeJS is used for processing the 3D model and automatically creating training dataset for machine learning. The AI/ML Part Recognition Engine is designed to be rotational invariant in all the 3 axes, colour invariant and scale invariant. Hence, we can give images of the parts rotated in any orientation about any axis and with any size.

For the Alarvy 3D Part Recognizer, initially 3D models of the parts to be recognized are given as input. These models are used internally for creating recognition datasets without any user interaction to train the Neural Network. This is a one time flow and after that, just an image/photo of any part in any orientation can be given as input for part(s) recognition. The input image can consist of only one part to be recognized or can consist of more than one part to be recognized.

Based on the input image, Alarvy 3D Part Recognizer can automatically recognize the parts along with their part name within milliseconds.

Alarvy 3D Part Recognizer took 18 seconds to recognize 6300 images. It is able to complete this with an accuracy of 98.16%.
