Snapping objects issue (cable) - PVsyst 8

[David Bourdon]

Good Morning PVsyst support and PVsyst community,

I'm creating this thread as I've been struggling for several hours now trying to draw an overhead line in my 3D scene and use the snapping function (by pressing CTRL) of the cable object to connect both ends of the cable (I use PVsyst for years now, so it's not new to me and I've done it several times in the past without any issue).

For some reasons, the cable object is not able to recognize the edge of my second shading object to connect. I've tried several type of shading objects to see if it makes a difference but so far still not working (parallelepiped, composed object from parallelepiped, electric pylon) The start point is never a problem but the end point is never found and can't connect to my second shading object.

I've tried to remove the other objects from my 3D scene such as topography, ground image, even the modules and keeping only the two "pylones" that I want to connect but it's not changing anything.

I'm using PVsyst 8.0.13 and tried as well with 8.0.12, but same effect. If I place my cursor where I want to connect the end of the cursor and then press CTRL, the end point moves to another location with nothing visible. I've tried to manually place the cable between the poles but moving in 3D it's almost impossible to do something clean.

If I start a fresh new 3D scene for the same project and try to create basic parallelepiped and connect the cables it works...

If you have any idea or advise to solve this...

Thanks in advance !

Best regards

After trying several potential options to solve this I may have found a possible explanation (but not 100%).

I've saved my poles as shading selected objects and started a fresh new simulation with a random meteorological file to avoid any external effect of my 3D : no effect, still not snapping.

I've opened the shading selected objects in PVsyst 7.4.8 and again started a fresh new simulation : no effect, still not snapping.

Then I've noticed that the snapping was working for several poles at the same altitude so I've tried changing the altitude of my other poles and then it worked with no issue. It means that depending of the altitude (I don't know what the tolerance is), the snapping function is not able to find the edge to connect the end of the cable object.

1st picture, they are more or less at the same Z coordinates ; snapping is working perfectly

2nd picture, the poles are at a different altitude, not snapping, mainly X coordinates which is affected by the poles location

 

Now what I can't explain is that the snapping is working for another pole at a different altitude, mainly with a Y coordinates affected by the poles location...

 

I can share a *.SHO file with my poles position and cables snapping/not snapping to help identify the issue, if necessary.

Thanks for your feedback,
