Solid Edge Lines Displayed as Hidden in Base View

Ryan7dash7 — Sat, 03 Sep 2016 18:54:08 GMT

I am having some trouble getting the base view in an IDW file to display properly. Specifically, some lines which should be solid are showing up as hidden. To keep the base view from becoming too cluttered, I want to use the "Hidden Line Removed" style. This causes some edges of the round flange to disappear as you can see in the image below. Interestingly, if I choose another view orientation the edges of the round flange show up correctly (for example in the back view at the bottom of the image).

I looked at this post (http://forums.autodesk.com/t5/inventor-general-discussion/solid-visible-parts-showing-up-as-hidden-lines-on-idw/td-p/2734533), but couldn't find a solution. I created the part in Inventor and tried the "Rebuild All" command to no avail. However, I noticed if I suppress the loft feature, the flanges display correctly. Does anyone have any idea what is going on and how to fix it? Thanks for the help!

Without the *.ipt file - I am going to guess that the Loft feature can be created in a better way.

What manufacturing process will be used for the feature?

Attach the file here and I will take a look at alternate technique.

Here is the IPT file. The transition will actually be made out of sheet metal using a press brake. I just used the loft feature as a quick way to show the overall dimensions.

Curious what you're seeing wrong ..attach maybe the idw ...

works fine for me

It's happen to me too ... interesting ... ? why is this all one piece?

Cleans up some left over rubbish on the inside. I expect issues when I see geometry that needs cleaning up like this.

When I get a chance - I will post alternate technique.

That's correct; I didn't know a better way to do it. I suspect an alternate technique may fix the issue. Here is the IDW as well.

By the way, thank you both for your replies! I wasn't really expecting anyone to respond over Labor Day Weekend.

Hi Ryan7dash7,

We have debugged the hidden-line computation and confirm this is a bug in Shape Manager (our internal reference for the bug is ASM-3544). Your model looks fine. Unfortunately I can't suggest a workaround.

Sorry for the inconvenience,

David Kershaw

Okay thanks for looking into it. I just submitted the drawing as is; it should have enough detail for it to be made correctly.
