[Nella Mcnairy]

Inclassical geometry, a radius (pl.: radii or radiuses)[a] of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.[2] The typical abbreviation and mathematical variable name for radius is R or r. By extension, the diameter D is defined as twice the radius:[3]

If an object does not have a center, the term may refer to its circumradius, the radius of its circumscribed circle or circumscribed sphere. In either case, the radius may be more than half the diameter, which is usually defined as the maximum distance between any two points of the figure. The inradius of a geometric figure is usually the radius of the largest circle or sphere contained in it. The inner radius of a ring, tube or other hollow object is the radius of its cavity.

For regular polygons, the radius is the same as its circumradius.[4] The inradius of a regular polygon is also called apothem. In graph theory, the radius of a graph is the minimum over all vertices u of the maximum distance from u to any other vertex of the graph.[5]

In the cylindrical coordinate system, there is a chosen reference axis and a chosen reference plane perpendicular to that axis. The origin of the system is the point where all three coordinates can be given as zero. This is the intersection between the reference plane and the axis.

The axis is variously called the cylindrical or longitudinal axis, to differentiate it fromthe polar axis, which is the ray that lies in the reference plane, starting at the origin and pointing in the reference direction.

The distance from the axis may be called the radial distance or radius, while the angular coordinate is sometimes referred to as the angular position or as the azimuth.The radius and the azimuth are together called the polar coordinates, as they correspond to a two-dimensional polar coordinate system in the plane through the point, parallel to the reference plane.The third coordinate may be called the height or altitude (if the reference plane is considered horizontal), longitudinal position,[7] or axial position.[8]

In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.

Has anyone else here created a variable radius round, where you have a few different areas that you need to add and modify, and you spend forever and a day trying to drag the little circles around the intent edge to get it where you want it? Wouldn't it be much easier (and intuitive) if after right clicking on the chain to make it a variable radius, that you can just right click anywhere on the chain and add a radius? You can right click on the handle of an existing radius to add another one, but it never goes anywhere near where I want it and I wind up dragging (and waiting for the display to update with the spinning glow ring).

3. What I'd like to see when clicking near the purple dot is "Add Radius", instead of what's showing. (I know the dot is close to the 4.000 handle, I just used it to illustrate my point about the menu).

Dave; PTC is millennia behind others on fillet/round performance. The real time UI is a huge drag on CPU/GPU cycles. And the intuitive UI rating is near zero. I don't know how anyone can design plastics without some some real horsepower behind their workstation.

I know this is one area that SolidWorks just shines! Unfortunately, I think PTC is pretty much committed to this UI and algorithm. As with all thing marginal in Creo, we're going to have to live with it. Maybe Creo 3.0 (?)

One thing I would -really- like is to have draggers be more intelligent by adding a "jump size" limit. By this I mean that between GPU refresh cycles, the dragger will only change maybe 10-20% max of the current value. A .01 value shouldn't suddenly allow a 5.0 value. If that is what you want, you can type that in.

It's a pain alright, but I worked out how to get it to behave better. When you right-click and select "add radius", the next thing you do is hover your mouse over the edge reference in the vicinity of where you want that radius to be located, then right-click again. Your drop-down menu will show a line, "location reference". Click on that and your new radius point goes straight there. Way easier than trying to drag the thing over and over and over.

Hi Everyone!

This is a question of curiosity in regards to the 'dot1x' configuration for Juniper EX3*00 series.

We have a new datacenter and when migrating the the RADIUS-servers we also made a complete change of the guest-wired network by moving it to a differnet /16 network and sending it out on a different IP not associated with our company.

I set up 2 new RADIUS-Servers in the new network with identical configuration for clients, policies etc..

I then continued to add the new radius servers to the configuration and when we made the network changed inactivated the dot1x protocol shortly before bringing them upp and everything was fine and dandy, all 4 serves worked fine, deactivating the 2 previous ones to the test the new ones was no issue, so i went ahead and shut down the previous 2 servers.

And boy did that make for strange issues, suddenly our Elastic Search solution flooded with dot1x discards while the denied rate remained the same and the authenticated users dropped like a rock.

Thanks to the 'server-fail permit' config in the profile no users were kicked out.

I reviewed the different switches and could see that some still consided the old servers 'UP' and some 'DOWN' or 'UNREACHABLE' depending on ELS or not.

After scripting out to have the old servers removed from config everything was once again fine.

What could have caused this issue? I understand that JunOS uses the authentication-order but it seems like it has been flooding the down servers with requests and had issues with the other 2 in regards with that.

Is there a way to avoid this? i know there is a whole Tunda for radius-message configuration on JunOS but im not experienced enough in that area.

Thanks for your time,

Andreas

By default, JUNOS uses round-robin to balance authentication attempts between all configured RADIUS servers. When a server doesn't respond, it's marked as unreachable. After expiration of revert timer this server is marked as UP again (without any actual check for "liveness" of the server taking place), and this process goes on and on. The following KB describes the revert-timer configuration option:

One thing to consider, too, is that the resolution of 3D printers, especially the ones normal mortals can afford, is not something to write home about. So using a zillion segments for small circles is in most cases just a waste of computing resources as the printed result will be rough anyway.

Do I remember right that @jimhami42 was the person who posted a nifty way to calculate the optimum number of circle and arc segments for a given radius and printer resolution?

I just changed my settings from mm to cm, pretending to be working in mm. Pretty happy with the outcome so far. Creating components and scaling is unnecessary complex. Are the developers active on this forum?

I have been exploring the dronedeploy functions and are very impressed.

However, sometimes I encounter a error message telling me that the corner radius are invalid.

What is the cause and how could I avoid receiving this invalid radius message?

Thanks for this. It should be very helpful. Chase is no longer on the forum and I do not believe he works for DroneDeploy anymore. @Erika_Houseman may be able to assist from here. Just from my experience the rounded turns look more realistic particularly with the new rotational-drift method of turning which is another reason why I am surprised that this is coming up.

Hello ,

I am a user of the ImageJ program and I have a [300 X 300] image. I would like to subtract background of the image, but I have a problem in determining the appropriate radius for the rolling ball as the biggest radius is 0.2 to 5 maximum value and I also have a noise problem. It has a filter but still exists in the image !!!

I am trying and trying, occasionally I get a leaf shape but 90% of the time I get a circle and I cannot figure out what I am doing wrong. The corner radius slider shows PT not % - once I saw it change to % but I cannot figure out how to change it at all - so sad to be stuck right at the beginning of the tutorials!

hey I think I am having the same issue. The corner radius only work on the selected nodes if at least one of the selected nodes have been moved first (simply momentarely distort the shape before making it square again) , otherwise all the 4 corners get affected and turns into a circle.

Thanks for the reply, it seems awfully glitchy, I have managed to change it to percentage on a few occasions now, but it really is driving me mad; if something this basic is so hard at the beginning it puts me off proceeding in investing in the time to go further!

I am working on a dataset using empirical bayesian kriging . EDA suggests using Log Empirical trasformation and a K-Bessel detrended semivariogram type. Without further adjustment, I achieved the "best" results (concerning error statistics) when using a smooth circular neighborhood type.

There aren't a lot of criteria of what is a good search radius, but there is plenty about what is a bad search radius. It definitely should not be larger than the range of the semivariogram (as you noted), and it should be large enough that it captures at least 10 points everywhere in the data domain. Other than that, there aren't many recommendations other than comparing validation and crossvalidation statistics for different search radii.
