AutoCad :: Changing From National Grid Coordinates To Local Coords
Jun 19, 2013
My father in law is a civil engineer but works everything out on paper. I'm convinced there is a better way (using autocad). I'm competent with computers but never used autocad in my life and I'm not a civil engineer.Before starting setting out on site, he is given the proposed layout, based on 'National Grid Co-ordinates' (in the UK).
Currently he's working on a carpark which is a nice grid but on a different axis to the national grid coords. To make things easier, he picks a coordinate and labels it Easting 100.000 & Northing 100.000. From there he converts the coordinates given to values relative to this 100,100 coordinate. He does this on paper.
When i pick points from the drawing using the ID command i recieve a long and meaningless coordinate which is useless to me when setting out. How i can rotate my drawing so that firstly its aligned with my grid and secondly give it the same coordinates as my site based local coordinated grid?
The drawings I'm receiving from the architects are all set to the world coordinate system. So when it comes to setting out they coordinates are useless to me. So what I want to know is how can I rotate my drawing so it's aligned to my local grid?
What I have is northing/easting survey data starting at an arbitrary point. The rest of the points are measured from that.
I do know the global coordinate of the base point, but no other points.
My question is how can I take all of the points and create gloabl coordinates out of them. I assume this is possible because I know the global coordiane of our reference point, I just have no clue how to do it in CAD.
I am modelling (low poly) a human head whose z-axis is not vertical. Now the problem is when I orbit it (using alt + middle mouse button), the head doesn't stay upright, and this is really not handy !!
The problem would be solved if I could, either orbit around local coordinates (meaning left-right mouse movements would spin around local z-axis, not world z-axis), or maybe change orbit style (for example blender has another orbiting style where left-right mouse movements spins according to view)
There would be another solution, which would be applying a rotation modifier to the whole scene, and removing when I'm done with the head, but I don't know if this is possible...?
I often create points manually. You get that dialogue box where you choose the layer and the default local coordinates, etc etc.
The local coordinates setting always defaults to Northing/Easting. (ditto the grid coordinates).
I set it to Easting/Northing as is standard around these parts and do my points, but if I close the box, when I reopen it to add more points later, it is back to Northing/Easting.
I cannot find a variable to control this behaviour.
I never need points to have north first and would like it to default to Easting/Northing at all times. Yes I'm using the Metric template.
Understanding that composite volumes are typically more accurate, I have a reason to evaluate the volume between two surfaces via a grid volume. Easily created a grid volume surface using a 50' grid (50' is large for this site, but wanted to get a feel for calculation time).
Question: Can you change the grid size without creating a new grid surface? Ultimately I woud like to explore the difference in volumes based on grid sizing without creating a long list of surfaces. One would expect that you could chage the grid spacing in surface properties, but the values are non-editable.
Now i am working on setting up the grid system for drawings . My task is after setting the grid label the possition of equipments od Data Center( e.g ups, panels) on drawing. I am able to set the grid but i don't know how to get my grid coordinate identifiers(x coordinates and y coordinates) which will label the equipments.
Apply the transformed utm coordinates to grid coordinates to a structure table. the point tables have a grid coordinate selection but the pipe structure table does not.
I'm trying to define a grid based on polar coordinates.
Can be produced using the following MATLAB n=1:50000;r=sqrt(n);t=360/((sqrt(5)+1)/2)+1)*pi/180*n;plot(r.*cos(t),r.*sin(t),'o')
I need to insert points based on the polar coordinates defined by the equations. I knew a little bit of LISP 10 Years ago, now it's a total blank. I've been trying to write a script to make this work but after 5 days I'm still without sucess.
That program by default showed (x,y) coordinates for pretty much any tool. This was really helpful when trying to get a circle around an object precisely. Is there a way to get this displayed in PS?
I am using PS CS (Premium Suite-Educational version).
I'm having a small problem with some drawings that have been sent to me for setting out on site. Basically I have 3 separate sets of drawings from architects and engineers, all of the same building but all using a different co-ordinate system. I know that the engineers is using the correct grid for my setting out but unfortunately I only have it in pdf. so I can't copy and paste layers from the other drawings into it.
Is there a way that I can alter the co-ordinates of the other 2 drawings in model space to shift them to the correct grid system?
I have a drawing at AutoCad and i want to change its coordinate like that
X'= X Y'= -Z Z'= Y
I know how to do it with the points (export their coordinates in a text and then transform the text and then import again at an Autocad) . But thus i loose all the line, arcs, etc .
There's a box, I've set it to 0,0 coords, but it will not stick to the top of the artboard. I've tried align to pixel grid on and off (It would not move off 0.318px when I had align pixel grid on, which confused me too!). When I turn align to pixel grid off the box stays closer to the top, BUT when I export for web it sticks a white line in at the very top of the artwork.
After upgrading to 3.6 I noticed that LR is creating duplicated folders if the name contains international characters, but only in the database - in the file system there is still only one folder.
In this case I had an existing folder "åre". I dragged some photos into it, but instead of them being added to the existing one, another folder with the same name showed up. It is impossible to move photos between the two "åre", as there is only one folder on disk and LR detects that the file is already there..
Random objects on my artboard tend to change dimensions and/or coordinates on its own. The difference is by a few thousandth of a decimal. I'm not sure when this happens but it's usually happening to objects I'm not working on in the moment. And once and a while an object would refuse to comply when I try to readjust the dimension or coordinates.
Why this keeps happening and what I can do to stop it?
I have excel tables that contain 4 columns of data.
The Y co-ords pf the required object The X co-ords pf the required object The rotation of the required object The object number
What would I need to do to insert a block at the coordinates to the rotation shown then have a leader with the point number labeling the block (but the text not be rotated to the angle of the main block.
My (previously wonderful) local adjustment brush has apparently quit working. Whenever I attempt to make local adjustments - using either the standard presets or custom settings - all the adjustments made are applied to the entire image, not just locally. Density and flow are set to my typical values and Show Selected Mask Overlay shows the extent of the applied effect, but whatever adjustment I make is applied generally, over the entire photo, rather than to the selected adjustment area.
URLs....every tool useless without closing and restarting Photoshop.It always happens for me after the computer has been in sleep mode, although I have seen it occur out of nowhere from a fresh boot.I'm using a completely generic 3 button MS optical mouse with the generic MS driver, no other programs on my machine suffer from completely random mouse coords, including Photoshop CS3.
For replying with 'check your drivers': URL....
Here is the full system info for my machine:

I have an ai file containing a U.S. map with each state on its own layer and path. I need to be able to create the poly coords for each state for use in an image map.
I've created a 2-point persective grid on top of a cube (see image below). I'm tyring to recreate the cube and have started by inserting some purple squares into the right side of the perspective grid. I've drawn an ellipse at the corner of the original cube that I'm trying to copy, to indicate where I need my squares to stretch to.
How I can stretch my purple squares in perspective so that they match the end of the orignal cube as indicated in the image below? I've tried skewing but this doesn't skew in perspective.
How do I custom change the Canvas Colour? I don't want to use Transparency Grid hacks, I want to custom change the canvas colour so that it suits my other works.
btw, who forgot to implement the use of Illustrators colours into the transparency grid feature, leaving it using the Mac OS X UI colour pickers is a bizarre choice.
I was expecting that existing artwork on a perspective grid would move/adapt when changing grid properties like vanishing point etc. but it looks like the artwork just stays unchanged.
I couldn't find anything on the net - is there a way to change the artwork accordingly with the perspective grid?

I'm a GIS analyst trying to learn Cad. I'd like to place a single point in autocad model space at a specific Northing/Easting position. After reading several forum threads I don't think CAD allows me to change the coordinate system of model space from map coords to northing easting coords, as we can in GIS.
I have a user and when he's in sketch mode he trys to draw a line but it keeps on snapping to a grid. Both snap and grid setting are switched off. I can't find any settings he has different from my own set-up so I'm finding it hard to fox this problem. FYI, this user is a bit of a problem and tends to change settings without even realising he's doing it.
I was working on some isometric drawings for my CAD class and I can't seem to figure out how to get the grid back to the standard 2D grid view that I used to get when opening CAD. I now jusr get this dotted grid every time:
