Error using Grill Tool

khushank.ks — Wed, 10 Apr 2019 14:11:54 GMT

I am trying to make a grill out of a solid with a thickness of 0.05mm using the 'Rib' command.

The width and the depth of the ribs is also 0.05mm. However, I keep getting an error saying '... did not produce meaningful results. Try with different inputs'.

I am using Inventor 2018 Pro and the configuration of my pc is pretty nice.

Please suggest a solution. Thanks in advance. Part file is attached.

Before we get to the Grill tool: you must constrain your sketches, particularly the first one. Currently it is a rectangle with no dimensions at all, and not constrained to the origin. One little accidental nudge, and a complex grill feature like this might fail spectacularly.

Now, for the grill itself. After the same failure (I assume) that you experienced, I made the boundary sketch much shorter so as to work with fewer sketch lines, just to see if it could work. I was able to get the grill feature to work in this smaller area, as long as I left out one specific line (see below, the red one). I have no idea what it is about this line that is different from the others, but when I include it in the Rib profile selection, the Grill feature fails; when I exclude it, the feature works. The attached file is 2018 format.

Similar as Sam, I ran into troubles with Inventor's grill feature, and I didn't find an all-around way in Inventor.

I did some pingpong with STEPOut, opening in Rhino, extruding all curves to surfaces in a single operation, thickening and ending in more than 1000 solids.

Boolean unions seem to be not good in Rhino, so after that STEP transfer back to Inventor, and deriving to a simple body. After that cleaning up the result with a last STEP (attached)

Thanks for replying. This is exactly the grill i was trying to achieve.

But still this doesn't solve my problem as i have several other similar files to convert into grills.

Generally, this could have been done in Fusion 360, using the Web command.

But sad to see, that even a very simple test was failing.
