Methodology Number 1 of 2 | |
| Command: | 5 |
| Alpha Alias: | Arc Arc |
| Description: | Computes point of intersection of two arcs |
| Data Format: | 5 Set RadiusPt1 RadiusPt2 NearPt Radius1 Radius2 {[Radius1 Radius2] ... } ; |
| Problem: | Given point 19 as the radius point of a curve having a radius of 200 feet and point number 20 as the radius point of a curve having a radius of 150.10 feet. Set point number 21 at the intersection of the two arcs. |
| Solution: | 5 21 19 20 18
200 150.1 ; |
Data Description
| Command | 5 | Sets the point of intersection for two or more intersecting curves.
Only one point is computed even though the curves intersect at two locations. You must indicate your required point of intersection by specifying a point number that is located nearer to the solution to be retained. If you use the repeating feature of this command to compute the point of intersection of more than two arcs, be sure to enter a Near point that will define all the required solutions. If the curves do not intersect at all, an error message will be printed. The radius points of the two arcs may be entered in any order as long as their respective radius lengths are entered in the same order. |
| Set | 21 | Point number of the initial point to be computed. |
| RadiusPt1 | 19 | Point number of a previously computed radius point. |
| RadiusPt2 | 20 | Point number of a previously computed radius point. |
| NearPt | 18 | Point number that is located nearer to the required solution than the alternate solution. |
| Radius1 | 200 | Radius length from RadiusPt1. |
| Radius2 | 150.1 | Radius length from RadiusPt2. |
| {[Radius1
Radius2] ... } | | Repeating feature of this command. See Methodology 2 for more information. |
| End Command | ; | All commands end with a semi-colon. |
