BIM3DGIS model format converter with Draco compression is here, automatic surface reduction is even better!

How to directly import .dgn format model generated by Bentley software into Unity3D for presentation and logic processing? How to import 3D models generated by industrial CAD software Solidworks directly into Three.js or Cesium to build digital twin applications?
How to convert BIM/industrial 3D model format, but also export the model structure/attribute data simultaneously?
You will definitely look for various conversion tools on the Internet, keep downloading/installing to try and step on the pit, which is time-consuming and labour-intensive, and the result is often unsatisfactory.

Now, Opt Converter product helps you to solve the above needs easily!!!!

    The 3D/BIM/GIS software or model formats that Opt Converter supports to import include:

    (1) BIM format: Revit, Bentley, Tekla, Sketchup, Rhino3D, Nwc/Nwd;
    (2) 3D formats: CatiaV5, Solidworks, Siemens Nx (UG), Creo (proE), Inventor, stp/step, fbx
    (3) Process industry: PDMS, SP3D; 
    (4) GIS formats: Osgb (oblique photographic model), tif, shp, Las (point cloud);
    Opt Converter can export formats including: gltf/glb, standard 3Dtiles, fbx, obj, slpk.
    It can meet the format requirements for digital twin applications of Unity3D, Unreal (UE), Cesium, ThreeJS, Arcgis and other 3D/BIM/GIS platforms.
    Format conversion is just the base, Opt Converter can also perform automatic surface reduction of standard piping components in 3D/BIM models! Meanwhile, for the first time, the standard Draco compression technology is applied to the output of gltf, glb, and standard 3Dtiles formats, which greatly reduces the number of triangular facets in 3D/BIM models, and makes rendering of 3D/BIM models on open source platforms faster and smoother.
    Not only that, Opt Converter can also output 3D/BIM component IDs into the converted format (fbx, gltf/glb, 3dtiles, obj) geometry data, and realise one-to-one correspondence with 3D/BIM source model structure/attribute data outputted as DB data files.
    3D/BIM model file less than 100M free online conversion! If you have the need for model data confidentiality, we can also provide you with a local server deployment version according to your needs!
