Please see this post which discusses changing the appearance of the vertex symbol. It was from a year ago, but if things haven't changed, you'd probably want something like: sketchViewModel.set("vertexSymbol.size", "20px");

The 4.29 implementation of MapView.goTo has changed in an undocumented way that produces different results than 4.28 and prior, particularly in regards to rotation. Our framework allows the user to change the map rotation via various means, and we use goTo in order to animate the change in rotation, rather than setting the rotation property directly (which causes an instant change). In code, it looks like this: view.goTo({rotation:rotation}); When doing this in 4.28 and prior, the map scale was preserved, but not the extent. Starting in 4.29, the extent is preserved, but not the scale. In order to visualize this, see the images below. The first one is the starting state, where rotation is zero (i.e. North is "up"): Now, let's say the user wants to rotate the map 90 degrees counter-clockwise so that East is "up". (In the code, we'd set the rotation value to 270.) Here's what it looks like in 4.28: We see the scale has stayed the same, which is the expected behavior. However, here's what it looks like in 4.29: We see that the map has zoomed out one level in this case. Were my browser maximized at the time, it would've zoomed out two levels instead. If the user were to repeat this process, the map would continue to zoom out each time. Fortunately, this is fairly easy to work around by adding the "center" and "scale" properties in the call to goTo: view.goTo({
rotation: rotation,
center: view.center.clone(),
scale: view.scale
}); On a side note, simply setting the rotation property directly continues to work as before, where scale is preserved.

@Noah-Sager thank you, I see the downloads are available now. However, the size of the 3.46 API download is suspiciously smaller than its predecessors, and after looking into it, I see a very substantial portion of the compact API is missing altogether, as shown in the screenshots below: 3.45 3.46 Any chance we can get this fixed?

Rather than using a SimpleMarkerSymbol, you might try something like this: Create a Circle with the 5 meter radius. Using the circle's extent, determine the four endpoints for the cross. Create a Polyline with 2 paths, one path being the vertical line, and one path being the horizontal line. Create a Graphic with the polyline as the geometry, and a SimpleLineSymbol as the symbol. Add the graphic to the view's graphics or some other GraphicsLayer. Whenever the mouse moves: Calculate the distance between the map location of the cursor and the center of the polyline's extent. Translate the polyline so it's centered at the mouse's location.

Get the TimeSlider date. The timeExtent value you choose depends on the mode. var timeSliderDate = timeSlider.timeExtent.endDate || timeSlider.timeExtent.startDate; Clone the date and zero out the time components: var baseDate = new Date(timeSliderDate.valueOf());
baseDate.setUTCMilliseconds(0);
baseDate.setUTCSeconds(0);
baseDate.setUTCMinutes(0);
baseDate.setUTCHours(0); Get the number of hours between the two date objects: var milliseconds = timeSliderDate.valueOf() - baseDate.valueOf();
var seconds = milliseconds / 1000;
var minutes = seconds / 60;
var hours = minutes / 60; Set the layer's request parameters: UM1_CLOUD_WMTSLayer.set("customLayerParameters.TIME", baseDate.toISOString());
UM1_CLOUD_WMTSLayer.set("customLayerParameters.DIM_FORECAST", Math.round(hours));

One of the main problems is that your measurements are in feet, but the coordinate system units for Web Mercator are meters. Even then, one might expect 100 meters to be 328.084 feet, but that's not what the screenshot shows either. I've used the logic below to generate rectangles based upon user-entered dimensions, and it works. The "getRectangle" function is the main one, while "getMapDistance" is just a helper. I suppose the efficiency of this particular workflow could be improved since the circle gets created twice, but it is what it is. function getMapDistance(mapPoint, radiusInFeet, ordinate) {
var circle = new Circle({
center: mapPoint,
geodesic: true,
radius: radiusInFeet,
radiusUnit: "feet"
});
return circle.extent[ordinate + "max"] - mapPoint[ordinate];
}
function getRectangle(length, width, centerPoint) {
var mapLength = getMapDistance(centerPoint, length / 2, "x");
var mapWidth = getMapDistance(centerPoint, width / 2, "y");
var xmin = centerPoint.x - mapLength;
var ymin = centerPoint.y - mapWidth;
var xmax = centerPoint.x + mapLength;
var ymax = centerPoint.y + mapWidth;
return Polygon.fromExtent(new Extent({xmin:xmin, ymin:ymin, xmax:xmax, ymax:ymax, spatialReference:centerPoint.spatialReference}));
}

It appears this is driven by the layer's displayField setting. Perhaps you can try setting it to a different field name and seeing if that makes a difference.

You can get the extent of all the graphics, and then expand it a bit: var extent = null;
graphicsLayer.graphics.forEach(function(graphic) {
if (graphic.geometry.type == "polygon") {
if (extent === null)
extent = graphic.geometry.extent.clone();
else
extent.union(graphic.geometry.extent);
}
});
if (extent !== null)
view.goTo(extent.expand(1.5));

</html> Note that adding and removing a highlight is redundant because the popup adds its own highlight as well. Therefore, in order to get rid of the popup's highlight, I added code to close the popup as well. I also commented out the part where the view zooms to the selected feature...otherwise, the popup would always appear over top of the feature, effectively hiding it.

There isn't native support for this in the SDK since polygon graphics only support horizontal labeling (see the LabelClass.labelPlacement property). That's not to say you can't pull this off with a little extra work though. One idea would be to maintain a separate polyline layer where the polygons have been converted to polylines, and those polylines labeled instead, since the SDK does support drawing labels alone lines. If you make those polylines transparent, it will appear as if the polygon edge is labeled. Below is a basic example: <html lang="en">
