Drawing an Angled Line

[ChrisGrady]

Hi All - Please excuse my naivety I have only just started using Autocad and have only had some very basic training!!

 

I am trying to design a car park for our club shop and there is an arc which I need to put some spaces at a 45 degree angle and as the polyline is not horizontal or vertical I cannot get the angle right - can it be done when the original line is at an angle?

 

I hope that this makes sense!!!

There are a couple of options. One is Polar-Tracking and the other is direct distance entry. DDE input requires the length of the line and the angle. Ex. - 20

[ChrisGrady]

Thanks for the reply - I will have a go!!

[ChrisGrady]

Still can't get it for some reason - I must b missing something!! I have tried the DDE and although the angle is correct coming off a straight line it's not correct coming off the angled line!!

 

Hope you can help as I need to get this in today

Your best bet is to stick with Polar Tracking. It's kind of tough to explain here in a few short words. You might want to check your AutoCAD Help files. What you are looking for are the "settings" option.

 

What angle is the line drawn at that you are starting from and what angle is the new line that will be drawn from it going to be?

[ChrisGrady]

Because it's a polyline I can't find the angle of it - not sure how either! I will check the help files to see what there is.

 

The line I need to draw should be at 45 degrees

Nice graphic but you do not indicate what line your new line is being drawn from. I think that info might be helpful don't you?

 

Is the new line going to be perpendicular to this polyline?

 

Hmmm....are you putting these parking spaces along that line between the words "in" and "out"? Is that line curved or is it constructed from a series of straight segments?

[ChrisGrady]

Too true!! oops - sorry!! Is this better? it's between point A and B (obviously!!)

 

[ChrisGrady]

You are correct I will be putting the spaces on the line that I have highlighted - I took measurements every 4 metres from the horizontal line below the club shop doors and plotted the measurements in a vertical line then I joined the lines by using a polyline hence the angled line (the line actually represents bollards)

Try making a block of your parking stripe (at 45 degrees; maybe 135, 225 or 315 depending on the direction that the polyline was drawn) and use the Measure or Divide command

I might agree with this but it appears there are a number of line segments and the OP might not get the desired results.

 

Could the OP reorient his UCS with each line segment then draw the new line at whatever angle he was going to use?

 

What angle will be used?

Oh, I agree with that- garbage in garbage out. Seems to me it should be a curve (or a series of curves)

Yep, he could do that... the angle would be dependent on the direction of traffic flow. I would probably use Polar Tracking set at 45 as suggested earlier.

Thanks. The last question was really for the OP but you are correct.

you can set your SNAPANG to 45 and just draw lines. Basic. REmeber to reset SNAPANG to 0 when you finish

Sounds dubious at best since the "curb" in this case meanders along a curve comprised of line segments. Each line drawn would have to take into account the portion of the "curve" it is being connected to.

ReMark. I was pointing out at a very basic level of drawing you can just change the SNAPANG and draw. I have used this for 20 year. It is a very quick ( & dirty, maybe) way. I have a PIKSNAP (little lisp code) command too, allowing you to set your SNAPANG to that of a line in your drawing.

 

I'd have made a block with the parking spaces set for a "square" lot and insert it for best fit to the traffic flow and curbing - But then I am only an Electro/Mechanical draftsman, so what do I know of Civil works

[ReMark]

Sounds like you know what you're talking about. No offense intended.

none taken

[ChrisGrady]

Just wanted to say thanks to all of you for your comments - with my very very basic knowledge I have just submitted a rough drawing of the spaces and they seemed happy with that although I will be trying your replies for my own peace of mind!! Think I might need to go on a proper training course though!!

[Slaraffenmann]

I agree with cadvision.

I would also use snapang in this case.
