Why I need polyline instead using just segments - I will need total length of polylines in one particular layer for calculation of amount of concrete side stones of the road (I tried to explain about them in my previous post) Thats why I would explode it first and then assemble agian. Because with the fillet tool in ArchiCAD I will fillet all segments of polyline with same radius, but I need many different raduses for different segments. *Here is one little problem, if you would ask me why I explode polyline. I just give on keyboard command "o", select by mouse pointer object, give numerical meaning of distance on keyboard, and point by mouse - which side should program create new object.Įlse, as I mentioned before, sometimes the contours of some objects are given by splines in this case I can make offset only in AutoCAD unfortunately. But, step 3 is easier and much faster in this particular case to do in AutoCAD. Steps 1 and 2 I can make in ArchiCAD without pain as easy as in AutoCAD, the sequence of my actions is identical. (This is specific of my job - drawing masterplans.*) Then when changes are ready I 2) assemble these primitives again into polyline and then - tadaaa! 3) I make offset for new border stones and pedestrian walks which are parallel to the road. What happens in my process: when changes of masterplan are announced, 1) I isolate layer with polylines for example - the contours of the road, then I explode the polyline, change basic points, directions, radiuses, crossroads, parking places, bus stops and so on - and yes it is easier to make with exploding to primitives. (when offset distance becomes greater then smallest radius of polyline segment - it will graphically just stop process of offsetting, AutoCAD in this case just ignores arc segment and takes it off from the offsetted copy of original polyline) "magicwanding" is cool but sometimes does not work properly. I don't understand - polylines are editable in AC (and one-heck-of-a-lot easier to edit than in ACAD), why would you need to draw a new one? What's so different about "magicwanding" a polyline to offset vs. I mean it is easier to make offset of ready polyline which is editable and I can change it many times then to draw new kilometer of brand new polyline and only then - make new offset I'm sorry if I misunderstood something and for I still don't use "offset" tool. And sometimes the shape of the road or horizontal mark of the relief is represented by spline. I mean it is easier to make offset of ready polyline which is editable and I can change it many times then to draw new kilometer of brand new polyline and only then - make new offset for border stones, for example. If there is change in the building shape I have to change some additional parallel lines and so on. Now every time senior architect changes the configuration of these objects on the plan - it is chain reaction I have to change all the configuration of "border stones", pedestrian walks that go parallel to the road, and in masterplans which I work with the common length of these lines is kilometers. Now I have to draw some additional lines that represent concrete frames around the road, so called in my country "border stones" - usually piece of concrete 300(height)x150(wide)x1000(length) mm AND - what is very common for masterplans - they change often - before I give out final version there is usually some 10 sub-versions. This is called in my explanation "masterplan", excuse my English. The situation usually is following: I have some configuration of roads, pedestrian walks and any other objects over the ground (2D). The way it works - not quite logical - maybe this is because I've started to draft in AutoCAD. Don't take offence I know there is tool called "Offset" in ArchiCAD, and it is right in front of me on the "tools" panel since I started using ArchiCAD many years ago, but I still use AutoCAD for drafting masterplans and this is one of the main reasons - it is still very uncomfortable for me to use it.
