Week 5 Challenge

1. Aim:-To Create a dgn file where we are able to apply varios methods to draw tangent and insert curves between them.

Procedure:-

(a) Line Betwen Arcs:-In this method we have to draw 2 circle first,Now click on the line between arcs option from geometry tool bar.From where we can select these 2 circles with offset or without offset and trim both or none as well to draw tangent between them.Where it shows the solution used the Alt key of keyboard to apply and done.

(a) Arcs Betwen Points:-This method is used to draw an arc between two taken points as per drawing need,i.e. start/radius is the placement method.click on the first point then second and draw the tangent between them.

(b) Arcs To The Element:-Arc to element is used to draw an arc between arc and the elemet.first we have to draw arc upon a circle and now select the arc to draw a tangent through them.

(c) Arcs Betwen Arcs:-As the name imlpies that,First we have to draw two arcs in reverse direction to draw arcs between them.Now click on the tool arc between arcs and select these two arcs with zero offset and reverse option not compound,i.e compound is used in same direction arcs.Then trim and extend both apply and see the arc between them,where it extends to create complete Arc.

(d) Arcs from Element:-In this method we can draw arcs between two element ,simple arc and 2 point arcs where line not connected each of them.Arc between element and many more option to draw arcs from there.here we can see the point of curvature and point of tangency as well when trim and extend both option applied on that.

(e) Complex Transition between Element and Arc:-Here we can used any element and arc or both the arc as well to draw the tangent between them to see the ditch line as well

Please see the attachment

Result:-Hence We applied the different arc method to obtained the desirable tangent with radius as well.

2. Aim:-To Draw a square with different feature defination and used the ORD tools to draw fillet and champher at the corners as well.

Procedure:-At first we have to draw line between points of distance 500' and used single offset entire element toolbar to make inside 5' and outside 20' as well.Now all the element has to be complex using complex by element toolbar and apply feature defination on it to complete the job as per need.

Please see the attachment.

Result:-Hence We applied the different feature to make square with fillet and champher on different corners at required offset.

3. Aim:-To create point featured element using the point tools.

Procedure:-A point tool is a simple tool to insert point such i.e. signage ,utility,sample-point using feature defination.Through point along the element or between any 2 points.we can used the point tool to insert utility or E-inlet along the road at equal interval or spacing with desirable offset from road shoulder as well.Locate the point using angle resection or transverse method to set the element at required angles from utility point as well.We may also apply the "terrain model mesh" using the terrain contours to apply the point through out the located point element.We can Modify points changing the elevation and rotation as per need for drain and Utilities.

Please see the attachment.

Result:-Hence we can use different points feature to draw the utility,drainage,signage,Inlet along the road with accurate offset and rotaion too.
