Iterating on an Option

options generated by optioneer are a solid starting point, but they often require further refinement whether adjusting for efficiency, new constraints, or feedback from colleagues and stakeholders, iterating on options helps ensure they meet operational needs in optioneer, this is a four step process extracting centrelines buffering centrelines editing centrelines reevaluating centrelines 🌟 top tip make a copy of your option or polygon before editing it! this helps you track changes, maintain a clear record of your decisions, and easily share your progress with others 1️⃣ extracting centrelines navigate to the analysis tab if the options you'd like to edit are not currently part of your selection, click add to selection when they appear within the option selection panel, hover over one then select extract centreline from the ⋮ menu name the centreline we recommend reducing the accuracy from high to limit the number of vertices this may vary from 80% and below depending upon your use case navigate to data > lines hover over your line > ⋮ menu > copy copying the centreline means we can keep the initial extracted option for reference while making any edits in a separate space name the centreline this will be where you iterate, so including a description of what you plan on changing might be helpful too you can also use the point inspection tool to extract centrelines if the options are visible on the map, just select the option of interest, navigate to the point inspection tool in the bottom left of your screen > option of interest > ⋮ menu > extract centreline 2️⃣ buffering centrelines once you have edited your centreline, you need a buffer to replicate the desired route width that you'll continue exploring solutions within to buffer a centreline select your desired buffer width the buffer represents the distance from the centerline to one side e g for a total width of 500m, set the buffer to 250m your map updates automatically and the editor window will open on your screen note selecting custom lets you to set a custom buffer width the width must be greater than 5 metres and less than 50,000 metres to make additional edits, click anywhere inside the buffer area to open the point inspection tool then click the objects tab and locate your saved centreline under polygons hover over it > ⋮ menu > edit the editor window appears you can also access your edited centrelines under data > polygons note buffers are separate polygons that are not attached to the extracted centreline any edits to your centreline will not automatically update the buffer you will need to create a new buffer to reflect those changes 3️⃣ editing centrelines making edits to your copied centreline is similar to the process for editing a polygon laid out https //shared archbee space/doc/b0rmypunfnfmjhc4afytx/6bygfx3hagbq3dpjlaspf from data > lines hover over the extracted centreline > ⋮ icon > edit the editor window appears within the map on your map, click and drag the 🔴 red vertices to make larger adjustments to your line click and drag the 🟠 orange vertices to make additional vertices and finer changes the accuracy slider adjusts the number of vertices you can adjust higher accuracy makes the line more rounded and adds more vertices, increasing its complexity name your iterated line and give it a description, if needed click save to save your edits your iterated line is automatically added to the lines tab within data 🥳 top tip want to keep your team updates with the changes you're making? use https //howto optioneer ai/platform/tracking project decisions to notify them of your progress 4️⃣ reevaluating ce ntrelines re evaluating your centreline allows you to continue this refining process while initial options capture basic constraints—like avoiding designated no go areas or minimising length—they may not account for more specific priorities by manually adjusting and re evaluating the centreline, you can iteratively test alternative configurations and compare each version against key metrics to reevaluate a line open the setup tab > lines on the right hand panel select the name of your newly iterated line from the drop down menu then, click confirm features this step activates https //shared archbee space/doc/fmhwkrzrwmy8gdlwjw7f2/i32hezly1y1xutvvcjywk# text=between%20two%20points ,evaluation, %2d%20develops%20multiple%20routes if you navigate out of the setup tab while you are in this mode, you will lose any unsaved work if you have a corridor that you'd like to confine the search area too, choose it from the select corridors drop down under select configuration, select the configuration you'd like the line to be evaluated against then, select confirm configurations note at this point, you will most likely only have one configuration, set up by our customer success team these configs are the rules which tell optioneer's algorithm how to generate results enter a case name and a description this could be a good point to indicate the line is an iteration, and the changes you've made to it then, click evaluate this process usually takes 30 minutes you can check its progress from project home > case status preview if the case is successful, you'll find its associated results in the results library > results and within analysis > option selection drop down if the case is unsuccessful, use the c omposition chart in analysis > option comparison to examine which constraint(s) have been broken
