3D PDF Reader Customer Insights

1. I am nearly a layperson in that the majority of my CAD work lacked the computer part, and was just a drafting class taken in high school a long time ago, so while I don't need my hand held, I need something that just works without me doing a lot of tricks.

2. I have not found any other Android 3D viewer that works anywhere near as well as 3D PDF Reader! Keep up the great work!!Steller app! I use eDrawings 3D files a lot, their Android App is marginal.

3. This work perfect!The PDF loads correctly and is smooth enough, just one issue the app doesn't exit when I press the back button consistently need to minimize and force clear from memory directly.Does exactly what I need it to do.

4. Good for simple shapes but not super complex.To be perfect I need to be able to pull some dimensions (distances ,angles) and be able to save it.

5. Anyway, I want to do a project and need to examine small electrical parts before I order them.

6. I have downloaded it to open files exported to 3D pdf from Solidworks, but it can not open any of them.

7. My only request would be to add the ability to open files from Onedrive.

8. Then i downloaded this app just to view the 3d pdf and was amazed to know that it actually supports STEP files too.

9. Using this reader, I can show them my progress and have them comment on the design.

10. I was assuming it is only for 3D PDF buti could view igs, stp and other files also.

11. Fails with error code -10300It doesnt open anything more than 200kb.
