Linear Releases with API

Anonymous — Thu, 07 Jun 2012 10:36:51 GMT

Hi,

I'm trying to script some linear releases using the Robot API in C#, but can't seem to get my head around it. Can you please post an example defining a linear release?

What I'm trying to achieve is releasing all edges shared by two panels, but only on one of the panels to avoid getting to many DOFs.

Hope you are able to help me out,

Andreas

I think I'm getting closer to an answer myself. The following code runs perfectly, but doesn't seem to produce any releases on the edges. What am I missing?

IRobotLabel linearReleaseLabel = robotApplication.Project.Structure.Labels.Create(IRobotLabelType.I_LT_LINEAR_RELEASE, this.name);

RobotLinearReleaseServerlinearReleaseServer = robotApplication.Project.Structure.Objects.LinearReleases;

RobotLinearReleaseData linearReleaseData = (RobotLinearReleaseData)linearReleaseLabel.Data;

linearReleaseData.HX =

this.HX;

linearReleaseData.KX =

this.KX;

linearReleaseData.KY =

this.KY;

linearReleaseData.KZ =

this.KZ;

linearReleaseData.RX = toRobotLinearReleaseDefinitionType(RX);

linearReleaseData.UX = toRobotLinearReleaseDefinitionType(UX);

linearReleaseData.UY = toRobotLinearReleaseDefinitionType(UY);

linearReleaseData.UZ = toRobotLinearReleaseDefinitionType(UZ);

robotApplication.Project.Structure.Labels.Store(linearReleaseLabel);

RobotObjObjectServerrobotObjObjectServer = robotApplication.Project.Structure.Objects;

for (inti = 0; i < panelIndices.Count; i++) {

IRobotObjObject robotObjObject = (RobotObjObject) robotObjObjectServer.Get(i+1);

RobotObjPartMain robotObjPartMain = (RobotObjPartMain) robotObjObject.Main;

RobotObjEdgeCollection objEdges = (RobotObjEdgeCollection) robotObjPartMain.Edges;

for (intj = 1; j <= objEdges.Count; j++) {

RobotObjEdge objEdge = (RobotObjEdge) objEdges.Get(j);

if (objEdge.HasLabel(IRobotLabelType.I_LT_LINEAR_RELEASE) == 0) {

objEdge.SetLabel(

IRobotLabelType.I_LT_LINEAR_RELEASE, this.name);

}

try to add

robotObjObject .Update
robotObjObject .Initialize

to the end of if

Hi Rafal,

Thanks for the reply... Unfortunatly it still doesn't work. The label is is created without any problems, nevertheless I tryed changing the label to a Robot native one:

objEdge.SetLabel(IRobotLabelType.I_LT_LINEAR_RELEASE, "pinned");

And I know for sure that the line of code is running, but it still doesn't work. Is this not the right way of applying a linerar release label to an edge?

Thanks again,

Andreas

I need develeopers to check why SETLABEL and HASLABEL do not work for linear releases.

Hi Rafal,

Have you got any clarification on this?

I have not checked yet but operation by labels (set , has) as you did works only for supports for objects.

For linear releases you should use:

robotApplication.Project.Structure.Objects.LinearReleases....
