Error report when exporting to Solidworks using .IGS format file.The problem is that in this case, some chamfered surfaces will be lost, but the .obj and X-T formats will not have this problem.

Hi, please can you reimport the IGES design file into Shapr, let’s see if this also happens in the app?

Hi @wangzhide, to exchange data between Solidworks and Shapr3D, please always use the Parasolid (x\_t) format. It’s guaranteed to work.

I tried what you said and re-import .igs into Shapr. The software works normally, and there is no problem of chamfering surface loss on the PC side. But the new discovery is that the color is lost. And I waited for about 10 minutes before importing successfully. The .igs file is about 50MB, and the program flashed back once during the process. This may be related to what I use is not iPad Pro.

感谢您的解答，我今后会这样做的，这种曲面丢失情况似乎是随机的，我使用.shapr的文件格式在两个Ipad之间交换数据也曾出现过这个问题，这其实更难以让人理解。

It’s a general issue when exchanging design files between CAD tools.
For Solidworks we will reccomend you share files in X\_T(Parasolid) format as Shapr and Solidworks both run on the Parasolid engine.
