![]() The Manifold drawing tools are pretty good. I know this looks difficult when set out in words, but it only takes seconds in practice. The new point A' is the end of the specified arc. The new position of the line is A'B (A has moved to A', with B fixed). (You might want to make a copy of the line first, or draw some anchor points.) Then use the transform Rotate. To do the rotation from A, using just the GUI, select both the line AB and the circle about B. 936.3 / 5751.44 is 0.1674885 of the whole circumference (to 6 places), so the rotation angle is 0.1674885 * 360 or 60.296°, counterclockwise in this case so negative. What angle of rotation is that? The whole circumference is 2 * pi * 915.37, or 5751.44 (to 2 places). The circle has radius 915.37 feet, and we need to move 936.3 feet along the circumference from A. We could do this in SQL (using the LinePoint() function), but why not stay in the GUI for a change. METES AND BOUNDS GOOGLE EARTH WINDOWSHigh quality maps can be printed on any Windows compatible printer, or saved as graphics files, including PDF. Straight lines, curves (chords or tangents), acreage calculations, gap calculations, balancing. We need to proceed along the arc of the circle 936.3 feet, beginning by moving west. Informatik Mapdraw is an easy-to-use, powerful deed plotting system for land title insurance, real estate, legal and land survey professionals. Draw a circle with centre at B and point A on its circumference (NB not the reverse). Go to the far end of the line, point B, and activate the Insert Circle on Centre tool, and also Snap to Lines. (*The centre must be to the south of A, so that the circle will include an arc proceeding "westerly to southwesterly" from point A.) This gives the centre of the circle for drawing the arc. Click Add, Then Finish.Ĭall the far end of the line point B. In the Angle/Distance section, enter an angle of 180 (south*) and a distance of 915.37 (assuming the drawing is in feet). Activate the Insert Line tool and click once at A to start the line, then hit Insert to go to Dialog Mode. In a drawing, begin at the start point (i.e. Is there an easy way to use this information to draw the curve? Let me see if I have understood (since we never have to deal with this sort of thing here). Is there an easy way to use this information to draw the curve?Įven so, it looks as if we can follow those instructions to just draw the arc, then follow it. I picked a weird example because with such large curves, there's absolutely no way they can measure it to the 100ths of a foot, but anyway, that's the general idea. a distance of 936.3 feet to end of the curve. Thence in a westerly to a southwesterly direction along the arc of a circular curve to the left having a radius of 915.37 feet. The metes reads, for example, as follows: If this wasn't becoming a legal issue I would ignore it. The current deed I'm reading is for a road which does nothing but go from one curve to the next with few straight lines. However, the older surveyors used the distance around an arc with a certain radius. Modern surveyors have added a work-around for me by using the chord of a curve with chord length and direction written in the familiar metes style. In fact my current job requires that from 5 to 15 times a day. Ever since Tim Osborn created the amazing Plot Traverse add-in for Manifold, I've been using it daily. I've been successfully avoiding this issue for.hmmm.11 years now since I first started using Manifold. ![]()
