To draw some transient graphics onto the AutoCAD drawing area is pretty simple, through calling the () method which needs a Drawable object and a few other parameters to specify the drawing conditions.Though the EntityJig or DrawJig can be used to jig the graphics, as we did a few times before, we use the Transient Graphics here to draw temporarily since it’s obvious that either the EntityJig or the DrawJig is over killed.We’d better use using to create the PointCollector to better utilize the above feature as we always do to the AutoCAD.The PointCollector is disposable and when its Dispose() method is called things will be cleaned up properly in a single place.We can convert them into WCS with a little additional effort for sure when necessary.Īpart from this nice feature, a lot of other good stuffs in such a succinct but cool coder. As mentioned before, if some code/command works fine with UCS we can be sure that it works fine with WCS too as WCS is a special UCS, but vise is not versa! So to repeat one more time, it is a good practice to test code in UCS instead of WCS because nothing reasonable enough should prevent users from trying it in some UCS.īy the way, the points returned by the CollectedPoints collection of the PointCollector are in UCS.

Here is a screenshot to show how it behaves in AutoCAD.Īs can be seen, the command runs well in a UCS, indicating our Point Collector honors UCS perfectly. Do anything else to the collected pointsĮd.WriteMessage(Environment.NewLine + ex.Message) Public Point3dCollection CollectedPoints ", ++i, pt.ToString())) Public class PointCollector : IDisposable Let us extend it to support polygon point pick as well. We created a nice little coder, Point Collector, to collect points visually to form a window and a fence before.

We can specify the UseBasePoint, BasePoint, and UseDashedLine properties of the PromptPointOptions for the Editor.GetPoint() method to connect the current cursor position with the previous point input, as we did to the Fence Selection before, but it’s far from user friendly, especially for selection options like window and polygon. To make entity selections, we need to collect some points to make a fence, window, polygon, or so.
