Could somebody describe to me the variations between thé UCS ánd WCS please.? Consumer Coordinate Program (UCS) Globe Coordinate System (WCS) Typically, when I translate a stage it is definitely because my present view (.plan control) provides been rotated about the vicinity of my project I feel functioning. As I work in Civil, particularly transportation, I often rotate my watch to orient my images appropriately. That stated, the interpretation is needed because my UCS provides also been recently rotated and balanced to suite my present view, i.elizabeth., UCS Beginning = (10 4 0.0000), and WCS Source = (0 0 0) So what 's the advantage or the needs of transforming óf them?

Autocad Ucs Vs Wcs

Understand the World Coordinate System (WCS) All objects in a drawing are defined by their coordinates in the World Coordinate System (WCS), which cannot be moved or rotated. The WCS and the UCS are initially coincident in new drawings. This non–world coordinate system. It isn’t easy if you stay in the WCS, but AutoCAD lets you set a new UCS based on that sloping surface.

A advantage if having the capability to translate a put together into another fit system. Obvious, I know, so here's an example: No matter what your UCS is usually arranged to, the vIax-curve-getstartpoint function results a fit in the WCS. Being able to convert this WCS point into your current UCS is of great advantage. Hope that helps!. Thanks a lot RENDERMAN. I have got a small question please. I rotate the ucs ( X 180 degrees ) and placed a text message with these data, and it is inserted normally; (command '.text' (trans '(0 0 0) 0 1) ' ' 'this can be a text') And I inserted another text as sticking with, and it is usually also regular.

(order '.text' (trans '(0 0 0) 1 0) ' ' 'this is usually a text message') BUT when I went back with the UCS to Globe, I imply as the defauIt ucs of Autócad, the over two texts are rotated 180 levels. I am i am sorry, I could not recognize the make use of of TRANS functionality.:( Any little hint once again please. You're pleasant.:) Therefore if I recognize you properly. You have a painting (right-side up) You rotate the UCS 180 levels (upside down) Location some text (furthermore upside down) After that rotate the drawing back again 180 degrees (making the painting right-side up again).and today your text message is upside lower.?:?

Seemingly simple solution, don't rotate your UCS before making the text message.:wink: As fór the trans functionality, let's try this instance. If you wished to place some text at the start point of a series, and used vlax-curve-getstartpoint to get the coordinates for that stage, but your UCS was spun 90 levels, and it'h origin has been displaced from the WCS origins, then inserting text message at the coordinates came back from the vIax-curve-getstartpoint function (in WCS) would effect in a text object away from in space somewhere.

Whereas, if you use (trans (vlax-curvé-getstartpoint vla-óbj) 0 1) your WCS installation stage, would today be transformed to your current UCS (exactly where you stipulated). I hope that wasn'testosterone levels too confusing for you?:unsure: If therefore let me know and I'll observe if I can come up with a simpler example for you. Right here is definitely a great read: Also some information in this twine: As a extremely quick illustration of the outcomes of not really making use of trans, try each of thése: Wow:shock: GREAT. That exactly was what I am searching for to know. The second routine is definitely performing mainly because well as we expect while intending to place points.:D.

The first routine can be consuming my inserted factors a way from me.:Iol:. So the insérted points would transform the points to the angular degree of the present UCS without taking the account of factors' installation clicks.

Feel I right?:unsuré:. LEE with yóur two programs I got it quite well. Say thanks to you soooooo very much. Greatly appreciated. So the inserted factors would change the factors to the angular degree of the present UCS without using the thought of factors' insertion clicks.

Not very - The chosen points have coordinates essential contraindications to the UCS (Consumer Coordinate Program), whereas, the éndpoints of the collection enterprise must be defined in WCS (or probably OCS for some other entities such as LWPolyline). Therefore we must transform the UCS factors to be comparative to thé WCS. This cán end up being done possibly by make use of of a appropriate change matrix if we understand the UCS rotation, normal and displacement - ór via the tráns functionality.
