You can download the dynamo file and the corresponding family for labeling the axis grid here. here<\/a> download. For the definition to take effect, the family must be loaded in the project and explicitly selected in Dynamo.<\/p>\n The Dynamo file has already been commented on, but here is a brief summary of the logic behind it:<\/p>\n The first part of the definition queries all grid lines from the project and then converts them into lines that can be further processed by Dynamo - to generate model lines in Revit, as in this case.<\/p>\n This means that the grid is already visible in Revit, but without the labeling - of course we are not satisfied with this and will see how we can get the grid names:<\/p>\n Querying the names of the grid lines is not a problem in itself, as you can use GetParamterValueByName<\/strong> to get them out very easily. But how do we display them in the 3D view in the project?<\/p>\n My first idea was the model text, for which there is also a node in Dynamo - but unfortunately this can only be used to create model text in the family editor and not in the project environment.<\/p>\n For this reason, I have created my own family in which I have inserted a model text and linked its value to a parameter.<\/p>\n We want to fill this parameter with the help of Dynamo and give it the value that we previously received from the grid line. Now we just need to place the family with the help of Dynamo:<\/p>\n With FamilySymbol.ByName<\/strong> we can call up a family loaded in the project - simply write the exact name in a string node. Once the family has been called, it can be called via FamilyInstance.ByPoint<\/strong> can be placed at any point in the project environment. I will come back to the topic of point selection below.<\/p>\n In our case, we must also fill the \"Gridname\" parameter defined in the family with the name of the grid line - this is done with the help of SetParameterByName<\/strong>.<\/p>\n Now let's see where the grid designations should be placed:<\/p>\n Logically, we would like to place our axis designation at the beginning (and possibly also at the end) of the axis line. The nodes EndPoint<\/strong> and StartPoint<\/strong> but unfortunately in this case the font would overlap with the line, which is not particularly attractive.<\/p>\n For this reason, we are making a small workaround:<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
