Hello!I'd like to move several objects from left of the drawing to the right. I also have got difficulty with setting the exact point of the left, bottom corner of the drawing with respect to global coordinate system. May somebody help me with these two things, please?The screen from my drawing is shown here: http://images50.fotosik.pl/511/20a12918710089e7.jpgRegards!

Maybe you could isolate those layers, then move?And the point you want to keep, could you freeze the layer the geometry is on?In reality, there's MANY ways to do what you ask...hope that helps!

Is this an Assignment or something? These rudimentary tasks you're having trouble with seem almost classroom like.

Hey, when a mans gotta move an object, its gotta move! LOL

Thanks for answers!I have started reading the book "AutoCAD No Experience Required", I have read about 400/1000 pages and then stopped for several months because other things were much more urgent. In other words, no practice but only theoretical knowledge from some time ago.Recently my friend asked me if I can prepare for him picture of some kind of furniture. He gave me oversimplified picture of that written on sheet of paper. I started creating this picture in AutoCAD and encountered some difficulties, even if those may seem very basic.I lack many of the dimensions so I've decided to follow some kind of approach based on layers and temporary, auxiliary lines. I've created layer for main rectangle, then I've tried to set left, bottom corner at the given point with respect to UCS. I didn't know how to do it, so I've created other layer, with some square beginning at 0,0 and applied dimensional and geometrical constraints, because I've already read about this way of applying limitations. It didn't work, later the square was destroyed by further actions and it does not correspond to 0,0 of UCS.I've also seen that it is somehow possible to change UCS from 3D to 2D view. I have done it (changing radio button from 3D to 2D) and I guess application now considers this UCS as two-dimensional, but as far as I remember the picture of these two arrows of UCS was somehow different in that book after change from 3D to 2D than what I've got. But it doesn't matter, that's only UCS symbol, not so important thing. I need 2D picture because I guess creating 3D pictures would require too much knowledge from me which I don't have yet.So, setting bottom, left corner of main rectangle is first of my difficulties. The other, minor, is properly choosing UCS symbol.I've got several different layers. One layer is for main rectangle, the other for auxiliary (and useless) rectangle near UCS. Third layer is responsible for auxiliary lines (after all I was able to change solid line to other line and force AutoCAD to redraw the picture, what was not so intuitive for me - how could I expect that AutoCAD doesn't redraw so basic and simple pictures automatically?). I connect geometry and dimensions of auxiliary lines with main rectangle.The fourt layer is for auxiliary rectangles (like this one in which four smaller rectangles on the left lay). The fifth for main rectangles - I've applied other constraints between layer with main rectangles and layer with auxiliary rectangles.The most difficult part of the drawing is its center. It contains three horizontal shelves, one at the very bottom of the central rectangle (central, i.e. horizontally in the middle and vertically in the middle). So the bottom shelf in that central rectangle would lie directly at the bottom of that central rectangle. This is just because of different materials used for walls of central rectangle and shelves (bottom, middle and top shelf in the central rectangle - wooden shelves).The central rectangle has also some other feature, i.e. its doors. There are three glass doors - left, middle and right. I don't quite know how he'd like to enable those glass doors to move. I've asked him about drawing of some little things which may be used together with the glass and furniture to let those two properly interact (i.e. to open and close glass door). From his explanation I cannot really visualize if that would be just three row, horizontal wholes in the shelf to put glass to it or if that would be done in more sophisticated way. This is what he is responsible of doing in his job, I don't know much about it. There may be many different ways of doing it, I guess. As far as I know this is just introductory drawing, so some of the details may change. Basically, the last layer may be connected with glass elements.I don't know much about furnitures but my friend recently has started creating shelves. He works as a person responsible for repairing flats (apartment buildings), things like electricity, wc, painting the walls and all the other things in the flats, he's got much experience. He has created one or two shelves in last quarter of previous year and client was satisfied. But he draws the pictures with pencil on the sheet of paper.Summing up, my first difficulty was to set the position of main rectangle with respect to the origin, i.e. UCS. The other thing is connected with moving those four rectangles. I'd like to move them from left to right but I don't want to have those constraints destroyed and I want them to be held in smart way.By the way, there are so many geometrical and dimensional constraints (parametrics) that when I choose "show all" I cannot see anything. I've noticed that choosing "show" and then clicking the element from which I'd like to see its constraints, doesn't help much because, surprisingly, it doesn't show all the constraints (parametrics) connected with that element. I also have got some difficulty with dimensioning (or whatever it is called in English), i.e. creating those additional lines to show what the height or width of the given element is.I can write more but I don't really want you to be bored because of this monologue :).Regards!

Hello!I still don't know how to set the left, bottom corner of the main rectangle to stay in one, given point, with respect to the origin of the system (i.e. UCS). May somebody help me with that?Regards!

Alright, to set a line at bottom left, clicky 'line' command. then type '0,0' and hit enter. your first line point is at system zero. go from there.And the UCS defines what plane in space you happen to be on, not either 2D or 3D. You will not see or deal with the Z axis until you change into a view that allows its display. by defualt, your looking at X,Y. no Z.Oh and I wouldnt be attempting to mess with geometric constraints. It will only confuse you (and me, I admit LOL). Constraints are handy in 3D modeling. Autodesk added them to make it ...feel.. more like Inventor, LOLso there basically useless (im sure someone will disagree) in 2D drawings

Thanks for your answer![QUOTE=tulip3D]Alright, to set a line at bottom left, clicky 'line' command. then type '0,0' and hit enter. your first line point is at system zero. go from there.And the UCS defines what plane in space you happen to be on, not either 2D or 3D.

I know how to start a line at the point of 0,0. I started my drawing at 100,150 or something of this kind. However, when applying constraints, it moved from that point to somewhere else (its position change to 100,50 or similar). This is why I wanted to "dock" the left bottom corner of main rectangle.The other similar thing which I'd like to do but I cannot is: I need to connect bottom, left corner of two rectangles of different size, which have got one common point.[QUOTE=tulip3D]Oh and I wouldnt be attempting to mess with geometric constraints. It will only confuse you (and me, I admit LOL). Constraints are handy in 3D modeling. Autodesk added them to make it ...feel.. more like Inventor, LOL so there basically useless (im sure someone will disagree) in 2D drawings[/QUOTE]It was explained in the book AutoCAD NER (No Experience Required) in the section about 2D drawings. I use it mainly because I don't know many dimensions of the drawing. I simply use some random values, which would fit the drawing more or less. I will edit those later with that friend of mine, but I don't want to spend much time on changing everything. This is why I've thought that constraints (parametrics) would be useful. That would simply mean changing three or four values and the rest would be done automatically by the application without my attention (just because of setting those parametrics).Regards!PS I have found that using "Insert -> Block -> Create" and then "Insert -> Block -> Insert" fits much better what I wanted to do:[QUOTE=tulip3D]Hey, when a mans gotta move an object, its gotta move!

Ok, can you ground a component? is there a 'fix' constraint? without these, using constraints will prove tricky, the geometry will 'move' around, as you stated. besides, all constraints do is keep stuff parallel and perpendicular, ect. not needed in Acad 2D. I suggest removing/not using constraints for anything in acad...prolly not what you wanted to hear....but its true...unless SOMEONE ELSE out there in the wide world of CAD can assist.. LOL

Thank you for answer!This is what I'm asking about - I don't quite know how to ground a component.I've encountered many difficulties while using those parametrics. But I need to be able to somehow force AutoCAD to treat rectangles as rectangles and not to degenerate them. That's not a problem to use geometric constraints because they look easy and intuitive. There is a problem with dimensional constraints.I need to be able to easily make changes to dimensions (height, width of some elements) without need to spend much time on that. I simply want to make those changes fastly and to spend most of the time before making those final changes. I want them to be done automatically, based on constraints which are done earlier, while knowing only some of the dimensions.Is there any other way to do it? If not, I can list some of my major difficulties while using parametrics. Maybe there is remedy to them. Basically it is about geometry "moving around", too many lines if I choose "show all" (I cannot see anything if there are too many parametrics) and some weird behaviour of "show (parametrics for particular element)" (it sometimes doesn't show what I think it should).I know it doesn't look impressing but this is what I've got now: http://i1191.photobucket.com/albums/z479/johnyjj2/szafa.jpg I just wonder what other way I should've chosen before proceeding with my first drawing in AutoCAD.Regards!

Proceed by forgetting about constraints, remove them all...thats my best and only recommendation at this point.

Thanks for advice!OK, I have deleted all the parametrics. May you answer my previous two questions, i.e.:1. How to make such a constraint that two rectangles always will share the same point?2. How to set beginning of the whole picture at one single place?It is shown here: http://i1191.photobucket.com/albums/z479/johnyjj2/constraints.jpgMy final result of previous work: http://i1191.photobucket.com/albums/z479/johnyjj2/szafa1-final.jpgRegards!
