Any VB code sample on real time 3D surface drag like the "bulge" feature?

[liminma8458]

Hi,

I notice there is a new "bulge" feature in Inventor 2018 release which was also introduced by Brian Ekins some years ago. I want to achieve something similar in our Inventor program. Is there any VB.net or VBA code sample on this topic? such as real time drag on 3D point grid or 3D spline or surface. A real time drag as follow.

Thanks

Hi @liminma8458,

Can you please demonstrate the same in Inventor 2018 through UI or manually?

Thanks and regards,

Hi, Chandra,

"Bulge" feature first appears in Inventor Pro 2017 as shown in attached file.

Brian also made some demo in the minute 1:19 in this video: http://au.autodesk.com/au-online/classes-on-demand/class-catalog/2016/inventor-professional/sd17917#...

Just wonder whether do we have any similar Inventor API code to do this animation for 3D sweep and surface?

Thanks

Hi @liminma8458,

I checked with Brian Ekins. Bulge feature is in the process of implementation.

Bulge feature needs computation of NURB surface (bulged face). Each time the user moves the mouse needs to re-compute a new surface, create a transient surface body and then draw that body using client graphics. It will be done over and over to dynamically show the shape.

Currently, "Bulge feature" is not available in Inventor.

So, Inventor API does not support "Bulge feature".

Thanks and regards,

I just want to point out that Inventor has "freeform" faces which can be interactively modified.  Not exactly the same as the "bulge" feature, but maybe interesting.

Hi, Chandra and Jon:

Thank you very much! now I understand a bit of mechanism behind "bulge". You are very helpful.
