Trouble having intersections for horizontal and vertical paths

[preetdesai]

[ FlexSim 24.0.1 ]

I am having trouble creating intersection when some paths and horizontal and some are vertical. Just like a mesh or rows and columns. I am not having success to create intersection between horizontal and vertical paths. I do not want to use elevators since the concept I am working is where small AGVs can travel horizontal as well as vertical. Horizontal and vertical paths are exactly align at X axis so there is no offset.

You can add a horizontal plane in your model. Draw normal path on it, which connects to other horizontal paths. Then you rotate the plane through a path as an axis.

This doesn't look to be a supported configuration of automatic intersections. You should be able to connect them when using a path between each intersection rather than two crossed paths. This means more effort but you can code automatic path creation based on intersection points.

Thanks Joerg! That was my next step but wanted to see if there is any better way than that. Thank you!

Hi Jason! I tried to do that but I am able to join them on one side but not on the other side. You mentioned I can do it via code, can you share example script? That would be very helpful. Like a two horizontal lines and two vertical lines having 4 intersections.

Just set up your table defining the paths

and then run this query in a script console:

Table.query("INSERT INTO Objects()  (Class, Name, StartLocation, EndLocation, AccumulationType, AGVOrientation, IsTwoWay) SELECT  Class, Name, StartLocation, EndLocation, AccumulationType, AGVOrientation, IsTwoWay FROM PathDefs")

giving:

Here's the example:

Hi @Jason Lightfoot creating the path worked but when I create controlpoints on each intersections and try to move AGV on them, agv is not able to find the destination.

[jason_lightfootVL7B4]

Was that part of your original question, and can you upload your test model?

[preetdesai]

Hi @Jason Lightfoot ! As I asked in the original question, I want the AGV to travel through this horizontal and vertical paths but I was able to have the intersections. Now, with your solution I have the intersection for 5 x 20 metrics that I created. (Similar to the single square path that you have in the attached model). However, when I create control points on each end and then give destination to AGV, it is unable to find the path. I double that the end of one path is not snapped to the end of another path. I also tried finalizeSpatialChanges function but it did not work. I am unable to share the model but you can assume that it has 5 rows and 20 columns of the example that you shared snapped together. Attaching the image.

What I want is I should be able to give any intersection destination and the AGV should be able to travel there.

[jason_lightfootVL7B4]

I believe your control points need to be on the horizontal sections. Also the AGV Navigator doesn't support routing to intersections - it resolves travel tasks to control points.

[preetdesai]

Hi @Jason Lightfoot ! I actually put the control points at each intersections. So the travel command always refer to the control points.

Hello @Preet, Is the issue the direction of paths? I don't see any paths in your picture that allow the AGV to go up the grid. Could you share the model?

[preetdesai]

Hi @Jeanette F ! I am attaching the sample model.

Script 1 creates the path

Script 2 creates control points

Script 3 has a command to move the AGV to a specific control point. The error I get is that the AGV is not able to find the path. I even tried finalizeSpatialChanges function. But that deletes all paths. I am sure I am missing something here.

sample model.fsm

Hi @Joerg Vogel I tried this method as well. As soon as I rotate the plane with respect to Y axis, I see that it lost the itersections and AGV cannot find the path. Attaching the model. Also attaching two images (before rotation and after rotation). You can see that the intersections are not carried over.sample model.fsm

@Jason Lightfoot @Jeanette F @Joerg Vogel I was able to accomplish the goal using networknodes instead of path and control points.
