Revit coordinate system is very confusing. The UCSVP (UCS viewports) system variable controls whether the UCS in a viewport is fixed (UCSVP ON) or changes to match the UCS in the current. An orthographic UCS has its origin at the WCS origin. If the UCSORTHO system variable is ON an orthographic UCS is restored automatically when the related orthographic view is restored by the -VIEW command or selected on the Look From control.
Differentiate Between Ucs And Wcs In Autocad How To Properly UseYou will learn how to properly use the True North and the Project North. You will learn about the mysterious, super secret Revit Internal Origin. This post covers a lot of ground.![]() Read our post about the update. Edit 2: Are you using Revit There has been a few changes to coordinates. The World Coordinate System (WCS) is the internal, high accuracy (10 digits) and absolute coordinate system.Good luck. What is the difference between WCS and UCS in AutoCAD The UCS (User Coordinate System) is the system in which you are working. You can use w2u to find the WCS origin in terms of the current UCS: w2u(0,0,0) Filtering the X, Y, and Z Components of. Zwift forumIt is usually placed relatively to the Site. That means it's location is most useful when exporting and importing files. It can also be used to set the angle difference between the True North and the Project North. It is represented by a blue circle with a cross in the middle. The next step is to select the project base point and click on the clip icon.A red dash should appear on the icon. Actually, you should locate it in your Revit Template so you will be able to track it's location for all new projects. By default, importing or exporting a CAD or Revit file will be made relatively to this super secret point, therefore confusing many people.Now that you are aware of this super secret internal origin, you should locate it in a plan view using reference planes. Most users don't even know it exists. Best shhoting games for macAutoCAD Precise Input: Specifying Point CoordinateIf you have 5 feet length object, then draw 5 feet length line. First, let us discuss how we should draw in your AutoCAD drawing, relevant to your scale.We draw our object in real size. In this tutorial, we will discuss how we can give precise input when AutoCAD asking us for a point location. You will need to define points eventually. Some AutoCAD tools ask your confirmation for settings before asking you for a point. Well, I know this is not true. We only use scale for plotting purpose.We are drawing in a limitless area. They have cm length object, and because they plan to plot it to scale, they draw it 1 cm length. Click the dynamic input button in drafting settings group. We can use other units like feet, cm, or m, but I recommend you to use inch or mm for the first time.If you or someone turn it off, try to turn it on. So AutoCAD only recognize mm and inch? Only for plot purpose. So if you work in metric, and you want to draw 1 m length line, draw it mm. AutoCAD only has 2 units by default: inch imperial and mm metric for plotting.So we better use that two units to avoid confusion when we plot later about this. AutoCAD uses these keyboard coordinate entry formats. The most direct way to enter points precisely is to type numbers with the keyboard. In most 2D drawings, the Z-coordinate value is 0. You can find out the X,Y location of the crosshairs by moving them around in the drawing area and reading the coordinate values at the left end of the status bar.The X,Y coordinates should change as you move the crosshairs. Note in particular how the first two coordinate pairs use the same numbers 2,1 but the second pair defines a different point because of the leading symbol. AutoCAD locates absolute X,Y coordinates with respect to the 0,0 point of the drawing — usually, its lower-left corner.AutoCAD locates relative X,Y coordinates and relative polar coordinates with respect to the previous point you picked or typed. This non—world coordinate system, known as a user coordinate systemis so widely used that UCS now refers to every coordinate system in AutoCAD.Why would you want to diverge from the standard WCS? Although originally intended for 3D work, a UCS can be useful on either two dimensions or three.The WCS assumes that the north direction is straight up, but you may be working on a building layout where one wing is at a Then drag the icon by its grips to set a new UCS. He has spent a lifetime in the engineering field. To type a coordinate or distance that contains fractional inches, you must enter a dash — not a space — between the whole number of inches and the fraction. Here are some guidelines for entering numeric values when you work with feet and inches.When you enter coordinates and distances, both the dash and the inch mark are optional. If you start a command such as Line, pick a point, and then click the Coordinates area a few times, the display changes from coordinates Off to live absolute coordinates to live polar coordinates.Displaying live polar coordinates is the most informative mode most of the time. Clicking the coordinates readout cycles through these modes. ![]() X and Y co-ordinates increase in the direction indicated by the UCS icon. As your cursor moves over the screen area you can see the change in X and Y co-ordinates by watching the co-ordinate status area at the bottom left of the screen X,Y,Z. Second, the icon contains a figure Y and an arrow head which points from bottom to top along the left hand side of the screen.These first two parts of the icon indicate the position and direction of the X and Y axes. First, the icon contains a figure X and an arrow which points from left to right along the bottom of the screen. The 2D drawing plane that you see in plan when you first start AutoCAD can be thought of as the ground under your feet.This plane is known as the XY plane. You can think of the World Co-ordinate System as representing the real world. If you have just opened a new drawing the Z co-ordinate will appear as "0.The third piece of information contained in the UCS icon is the letter W. By moving the XY plane you are by definition changing the co-ordinate system. For example, to draw a circle on the vertical face of a box you would need to move the XY plane in such a way that it lay coplanar in the same plane with the vertical face of the box. No actual drawing was done in 3D.This method works very well for simple 3D objects, but say you wanted to draw a circle on one of the vertical faces of the box you have just drawn. To produce a 3D effect all you have to do is to change one of the 2D rectangles parameters i. Notice that to produce this 3D box you have only worked in 2D. Note that the pull-down menu allows direct access to all of these options.You can also gain direct access to the options from the fly-out UCS buttons on the standard toolbar or from the UCS toolbar. When you start the UCS command from the keyboard or from the toolbar you are presented with lots of options on the command line. All of these options are available to you when you use the UCS command. To move the XY plane the user i.As you can see from the two illustrations above, the UCS icon shifts its position to indicate the orientation of the current User Co-ordinate System. Notice that the background color is different grey which is good so that you remember that you are in the block editor and not in a drawing space model or paper. Your block will now open in the magical world of the block editor. The first point will become the origin of the new co-ordinate system.In the picture below, the scenario is that I have multiple instances of a block that contains attributes and the insertion point for this block is located at an odd location.Or an easier way is to. The three points represent three positions in the new XY plane. The 3point option prompts you to pick 3 points in space which it uses to define the position of the new XY plane.
