Drawing Circles

mdanbury
Hi,  Whenever I try and draw a cicle librecad just inserts one with a radius of 1, if you are doing a large drawing and move the mouse even slightly you then can't find it as it seems to be only one pixel across which I then can't see on the screen so I have to zoom in until I can then find it so that I can then set the correct radius via modify properties and then zoom out again.  Is there a better way of doing this?

Regards

Mike

The command line asks for the radius.

When I use the circle/radius command, I select a center point but the command box does not advance to the radius input.  If I use the enter key, the operation is completed with a predetermined radius with no opportunity to input my value.  What do I need to do to have the program recognize to that I have used the mouse to select the center and advance the command input for the radius?

FYI, to get that display, I had to turn on tool options in the toolbar menu.

Again, thank you.

How did you install LibreCAD?
What is your OS?
Usually the tool option bar should be enabled by default.

I installed from an internet download.
I am running Windows 10.
It may have been enabled by default, but I have tried to remove some toolbars to free up some screen space, so I may have turned it off not knowing what its function was.

Your response was very helpful when I was working with the circle command.  I have years of experience with AutoCAD and Draftsight.  I expected that executing these commands would be intuitively obvious, but it is not working for me.  You guided me thru using the circle command.  I just tested it again, and it is working as you described.  I am now trying to use the offset command.  I initiate the command and select the line that I want to offset.  How do I move forward from there?  I need to specify which side and the offset distance.  What do I need to do to advance from the selection step?

Thank You,

John Walvoord.

Close selection with Enter (you can select several entities), set the distance at the Tool Options bar and click into the screen at the desired side.

What is the syntax for specifying an x,y coordinate on the command line?

Absolute location: x,y
Relative to the last point (small red circle with cross): @x,y

I did this successfully with two positive points, but it gives me an error if I enter a negative number.   ?

@-100,-100 for second point works for me.

How did you write it?

What was the error or error message?

I wrote 16,-12 and got the error message.   Is it possible that I have the drawing limits set to only positive limits?   If so, how do I change it?

16,-12 works for me when specifying a point for a line
About positive limits on the drawing:
If you can draw a line with the mouse on the negative area, then no, there are not positive limits in your drawing.

It would be interesting to know what exactly the error message is so somebody could search its text inside the sources.
Also what exactly did you to get that error, something in the style of "click on the line 2 points icon" then "click on the commandline widget" then "write 16,-12  and hit enter"
and maybe also the version of LibreCAD you use

Re: Circle Drawing with radius command.

Thank you for your response.  I am going to try to make this as detailed as possible and respond to all of your points.

  • I can use the snap selections to draw the items I want anywhere on the drawing.
  • The version I am running is image.png
  • One operation that I used that gave the error is simply a circle command with center and radius.
  • I entered 16,-12 and pressed enter resulting in the following:  image.png
Thank you for your help.  I look forward to hearing from you.

Best Regards,

John.

Re: Circle Drawing with radius command.

OK, let's try again. I have the same version running as you.
Initiate the operation with Tools - Circle - Center, Radius.

In the Tool Options bar above the drawing area an input box for the radius appears. Set your radius there. I decide for 20. A circle with radius 20 will immediately hang at the drawing cursor.

At the same time you are asked to specify the circle center in the Status bar at the bottom and in the separate bar under the command line window. Click into that bar and you get a blinking cursor there indicating activated and ready for input.

Type in:  16,-12  and press Enter.

     


It can happen that you don't close a previous command completely, it expects a repeated, continuous execution. But you may think you are doing a new command. This might produce confusion about the syntax. So if not sure end the previous command with a double Escape.

Re: Circle Drawing with radius command.

jww153@gmail.com
So, I experimented using a circle, radius command with the radius set to 0.125.  I entered the center location as 1,1 and it worked fine, 2,2 worked fine, 4,4 worked fine, but -4,4 gave the error as shown.

1,1

2,2

4,4

-4,4

Expression Syntax Error


I am starting to wonder if there is just a bug in my installation that does not recognize my "-" key.  Any thoughts?
