Query for X-Axis of a Plane

john_hauck

How do you create a query for the x-axis of a plane.
For example, create a linearPattern, where the directionOne is the x-axis of "plane".

Here is an example of my goal (search for "HELP").

My mistake, I misread your script. You'll want the first argument to those functions to be id + "sketch"

FeatureScript has two different kinds of "id" - operation ids use the Id type and are hierarchical arrays. Sketch ids are just plain strings. sketchEntityQuery wants one of each: the operation id of the sketch (id + "sketch") and the sketch id of a specific entity within the sketch (given by the skRectangle function... which just concatenates strings to make edges of "tile.left" etc.).

Your confusion here is, frankly, pretty valid. We'll make a priority of documenting various sketch functions to explain this behavior better.

For the pattern directions, one option is to use sketchEntityQuery(id + "tile", EntityType.EDGE, "tile.left") and sketchEntityQuery(id + "tile", EntityType.EDGE, "tile.bottom"). We should document skRectangle better to make it clear that this is possible. Another option is to use opPattern directly and make a list of transforms with a double for loop.

For identifying the different sketch regions, unfortunately the only option is to use something like qContainsPoint to disambiguate the regions. The regions that result from a sketch solve are not directly associated with the edges you create when sketching (for instance, a sketch with two rectangles and a line can produce up to six regions, each touching edges from all three operations). So if you put those operations in the same sketch, you need something like a point in space to specify the exact region you want.

Alternatively, you could distinguish the regions by simply putting the two rectangles in different sketches. Performance-wise, I suspect a single sketch would be faster, but only the profiler can say for sure.

For the pattern directions, I made the changes (lines 75, 79). It now fails to generate.

Is it because of the way I defined the Id for skRectangle: "tile" vs id + "tile"? (line 43)
Is it because there is an extrude with an Id of id + "tile"? (line 55)
I think I ruled out those possibilities, so I'm sorry but I might need another hint.
