VW2016 Crash on Extrude Along Path

[CarlJdP]

Hi all, I'm having trouble with extruding a 2d polygon along a nurbs curve.

The 2d polygon is one of many to be extruded along this path, so it is slightly offset from the path, and thus I select the [fix profile] option. I noticed that if I deselect [fix profile] the crash does not occur..

Every time I run this command I get 'VW 2016 needs to close down' ?

Does anyone else get the same crash as I do?

It crashes for me too. If I change the 2d polygon to a NURBS curve too I get an error message. If I switch the direction of the NURBS path it crashes again.

The profile has a stacked vertex where the top of the bread loaf meets the overhang. Delete the extra vertex and the EAP works as expected.

I hate it when those vertices stack up.

Hi,

File as was downloaded worked fine for me.

Windows. VW2016. SP2

Whoa, Alan - it didn't crash for you? The file crashed for me when opened then EAP.

Could this be a system config thang? My rig is OK - pro laptop, but nowhere near state of the art cpu/cores or memory. or Win/Mac? But CarlJdP is Win with Nvidia 780.

Anyway, looks like there is a workaround on the Mac side.

@Benson Shaw

Thank you, the stacked vertex explains it Would be nice though if Vectorworks could catch this exception.

@JimW / @MarissaF

Would be nice, with a lot of the tools, if the FAILED error message could state why the operation failed, or which objects caused it..

Adding this thread to the existing request for more informative solid modeling error messages.

It would also be nice to add a wish for a way to find/delete coincident points. This is a leading cause of geometry issues in VW yet there's no way to easily repair this issue. Its easy enough in a situation like this (+- 10 points) if you know what you're looking for. But when you have 100s of points it can be a nightmare.

Simplify Polys should do this. Usually the Minimum Deviation mode is what you'd want to use, at any setting greater than 0 but larger than the smallest rounding precision unit in the document stacked vertices should be removed.

[Kevin McAllister]

Thanks Jim. Great tip! Actually using the tooltips I discovered that a maximum deviation of 0 will remove collinear points which is a little simpler. (Often you need to only remove collinear points but not change a path's shape.)

I didn't know 0 would work! Ty, I'll make an article out of that actually for the kbase.

[Benson Shaw]

But you still have to know that coincident vertices are the problem for failed EAP or other fail. Currently, the stack shows a slightly darker vertex marker.

Could stack indication be enhanced with a different color or larger marker?

I would say a visual indicator would be a good wishlist item, I'll submit that. However, I would also say a pre-check might be in order so that an EAP could at the very least WARN a user about a stacked vertex, and ideally either fix it automatically or avoid it becoming an issue.
