How to Set Points at Angle and Distance in 2d Drawing
March 26, 2020, 03:29:50 PM
This seems like it should be pretty simple, but the only ways I can figure out how to do it are kind of cumbersome.

I'm setting a transit up on a baseline and locating points by turning angles from the baseline and measuring respective distances.

I want to plot the resulting points in a 2d drawing, using TC 2018.  I can do it with a series of angular, perpendicular and parallel construction lines.  Then erasing the construction lines.  Or, by drawing a line that extends an angle and distance - and then erasing the line after I establish the point.  Not difficult to do, but seems cumbersome for a program with all the TC features.

Is there a simpler way to do this?  I have a vague recollection of my DesignCad program allowing me to set a point at an angle and distance.  Can't find such a feature  in TC.

Down on Inspectorbar, open the selector property and make sure they are checked.
I dont believe you can do it with Points, but it will work wit Polyline in example.

Maybe try inserting Point Objects, while in Relative Coordinates mode.

Polylines are drawn with successive relative angular vectors.  You could export the polyline's vertices to .xyz file with TC Coordinates palette and use Ruby to import that file as x,y,z points.

There's delta distance and delta angle the last two items on the inspector bar.  Draw your first point, select it and use those fields with "make copy", the selection focus moves with the copy, so tab successively through into the fields and re-enter.  Takes 19 tabs to cycle through for full IB, but you can go to the selector 2D or 3D properties and pare down to only those two fields uncheck all of the other option fields, and then tab takes you straight back into the distance field after enter, like you'd draw a polyline. It's repetitive vector copy, really.

If I'm correct in inferring that the transit remains fixed, then the Polar Coordinates mode will do the job. I'd never played with that before my previous post and I had to experiment a bit to learn how to use it, even with "help" from Help.

The OP refers to baseline, you refer to transit, Henry.  You think the vectors refer to a single origin?  If that's the case, it can be done with vector copy set to repeat, place a point on the origin and leave the cursor hovering over the origin, invoke pickup of the point's CoE with the E SEKE, tab through distance and angle IB fields, enter, repeat.

After some stumbling around with the Help feature, Polar Coordinates looks like it will do the trick.  I can relocate the origin to the point where my transit was set and mark points at angles and distances just like I measured them on the ground.  Then go to the next transit setup point and repeat.

I don't think it was called Polar Coordinates in DesignCad, but this does the trick.  Thanks!

You don't need to be in Polar Coords.

Lets say you want a point 3 units at 45 degrees from 0.

> hit enter

In Design CAd it's called Point Polar and comes with a few more options.

That's good, Murray. I never have Delta Distance and Delta Angle enabled on the IBar and I'd forgotten that these options existed.

When I do this, the X and Y fields are set for distances.  How do I make the Y field recognize an angle entry?

Oops.  I missed the ">" in front of the Y entry.  Yep, that works also.

This technique worked great!  My first backsight was parallel to the X axis of the WCS, so I was able to turn the angles directly from my transit readings.

My second backsight was at an angle to the WCS X axis.  After a bit of reading I figured out how to use Workplane by 3 Points to establish a UCS X axis to again turn the angles directly from my transit readings.

You can also use @ in those boxes to make a value relative to the previous point instead of absolute.

Cool.  And Useful.  As Henry said-- the trick is to remember to remember to use these Murray's tips.
