AutoCAD 2010 :: Merging Two Drawings Of Different Units
Feb 22, 2012
I sometimes am given drawings which are done in a software package called LSS of which I do not know much, these drawings are usually to show a model of a band, by using contours of a site on which I am working and are saved by LSS in a dxf format so I can then import them into my autocad drawing.
The problem I have is that I also have drawings of the same site from a surveyor which has the buildings new and existing, but they are in different units.
The surveyors drawing for instance the grid measures 100000mm whereas the LSS model drawings the grid is 100m.
This means the coordinates are different so it is difficult to match them up , the only way is I have found is to rescale the LSS drawing up by 1000, then find a common intersection i.e. corner of boundary line. This is not always very accurate.
The guys who do the LSS drawings tell me they cannot change the units to mm.
I am trying to bring an element (a building's floor plan) in one drawing into another drawing where it can be joined onto another building and the site plan.
The thing is, the UCS of the destination drawing is different from the first drawings. The Y-Axis in the destination drawing is pointing somewhere beyond the 3 O'clock position while it is still at 12 o'clock in the first drawing.
How do I determine the exact angle of the rotated UCS in order to insert the element at the right angle?
I have a problem with my autocad. The administrator started me out on AutoCAD 2012 global.
The problem existed then so. Now he has me on AutoCAD 2012 Imperial . The problem still exists.
When I open an existing drawing that I have never opened with my version of Autocad. It opens the drawing in Metric units. I do not want Metric units. I would like it in Imperial units. Every time I open an existing drawing, I have to change the units to Architectural.
I had tried to draw in different units in autcad other than inches, but fail to find i way. I tried going on tutorials, but all they say was to type in:
"Type in Unit in command
Press enter
A option will pop up
Change Units to whichever.
Okay so I tried this, and I change it to feets. The problem is, that whenever i draw a line, it would always be in inches. I want to find a way to draw in feets, so how I can do this.
So we have started some work overseas and I have been trying to make sense of the metric units in CAD. Metric units in general, make way more sense then imperial units but how they work in CAD has been confusing.
I am familiar with the UNITS command and have changed the drawing units to "decimal" and the insertion units to "unitless"
I know that when you draw a 1 unit line in model space it could represent a 1 millimeter line or a 1 meter line and that it is up to the drafter to decide what it will be. I also am familiar with setting up dim styles to dimension correctly based off of whether you are drawing in meters or millimeters.
I have set my Adobe pdf printer to A1 23.4" X 33.1" (594mm x 841mm). when I draw a 1 unit line in paper space and print the layout the 1 unit line measures 1 inch?
i have a number appear when a get the AREA of the attached rectangles shapes especially when i use SMD ucs.for instance see the rectangle C07 74 X 39=2886.00000000 BUT i get the area like 2886.000000003.why the precisions doesn't all 0...
I have a query on the units for Autocad, every time i start Autocad up it defaults to inches, i have to change the units manually to mm using in units. is there a way to set this that i don't have to keep doing this?
how to open AUtoCAD 2012 so the default units are set to imperial? I only have one autocad icon (as opposed to a metric and imperial icon which I have seen before).
a) can send me geological elements hatching patterns in .PAT format to g.jamalashvili@gmail.com (e.g. hatch for tuffs, basalt, tuff breccia, andesite, dacite, diabase, etc), or
b) Websites where I can dowload them or otherwise buy them quickly...
I'm using the exporttoautocad command to convert a 3D drawing with a proposed surface (a TIN object) into a drawing with just contours (polylines with elevations). My original drawing is in feet and has a NAD83 state plane coordinate system.
Everything seems great in the exported dwg, except it is converting the elevation units from feet to inches!? A contour that was originally at an elevation of 7.0 feet, ends up at 7 inches in the exported drawing. Spatial coordinates are preserved.
We have some machines which seem to work in imperial maesurement a dn others which work in metric. it is frustrating when trying to insert a map block that is metric and is inserting into a drawing which is set up as imperial. We have tried using the - dwgunits to change to mm, and then using insunits , insunitsdef source and insunitsdeftarget to 0, this works when the PC is currentyl in use. when shut down and restarted it reverts back to imperial setting.
Am i right in thinking this is something that needs to be done at the software installation stage to make it default to metric everytime?
I have a venue drawing that is in mm and I need to convert it to ft/inch so I can update and get dimensions from it. Can this be done so when I change the format in drawing units it will update the drawing units?
Current settings. Drawing units Length: Type - Decimal Percisin - 0
I want to chose the better, to start drawing. I use inches at work, but I want to use international system for myself for personal projects
I think there is a standard unit in files imported o r exported from another soft, smaller files, easier size to process by pc, quicker units to introduce, accurate, prototyping models soft compatibility, etc.
Any previous criteria for recommendation is perfect.
¿Which is the best measure units to use? Spoiler (Highlight to read)
I'm using Cad 2011,how do u generate 2D drawings from a 3D object,i know that the command only works on layout n on 2013 the command is "Base".So wat is it on 2011?
I am using 2D-AutoCAD, and trying to plot a drawing on a printer, the drawing is different colors and I want to print it black on white paper, I am unable to select the proper .ctb file from the Plot Style Table pulldown, it does not show up? I have plotted other drawing sets using this method but for some reason cant do it on this particular set.
I need to have two people working in the same dwg, basically at the same time. We call it an Assembly Plan. Everything is done in model space. I want to be able to have each of them basically work in the same dwg and at the end of the day, BOTH of their work is saved in one dwg, but no double lines, etc.
What is the best way to get 2D drawings from a 3D model? Flatshot will give a flat view but it does everything in the entire drawing and brings every line with it.
Is there an easy way to get a 2d drawing from one thing in a 3D model? We only have Autocad, no extras like Revit.
Where the majority of people annotate their drawings. A major improvement I recommended to the plans was to place our annotations in our XREF drawings instead of placing them in model space of our sheet sets. (Our sheet sets are our drawings that have our titlblocks that we plot from ). So, I am asking where do the majority of CAD users like to add annotations to there drawings? PaperSpace, model space, xref’s, etc. and why they do it that way?
I should also state that we are transitioning from 2012 software to Civil3d 2014 software too.
I have been trying to figure out how to copy a Layout from one DWG to another. I know there are several threads about this, and I have tried the methods they reccomend, but I am having an unusual problem.
I have been trying to open a Layout by using the "from Template" option for creating a new Layout, then opening the DWG containing the desired Layout. It works, but everything drawn in model space ends up compressed into the lower left corner and there is nothing in model space. So, the paper space information from the Layout is being imported, but the drawing info is getting mixed up somehow.
I have tried using the Design Center with identical results.
I have built a 3D turbine that combined more than 50 3D parts. Now I want an assembly drawings to show our clients how to put those parts together. Any autodesk software? Some people recommended Inventor and I have never used it. Is this a right software to do some kinds like this project?
Recently I started using AutoCAD 2012 and I ran into one problem which I didn't encounter before.
The problem is that when I try to paste objects from another drawing (through clipboard - usually another instance of AutoCAD) I can't paste them in some drawings only.
The following things happen:
-Autocad behaves normally like when I usually paste objects except there is nothing inserted. -When I save the drawing after unsuccessful insert, even if I canceled inserting, drawing size increases dramatically (for about 2-4MB). -If I open new drawing, I can insert objects there. -Also when I copy to clipboard, autocad takes a lot of time even if it is only few lines.
I tried these thing to fix issue:
-I checked if there are any layers turned off. -I tried to copy with COPYBASE -I restarted autocad (sometimes it works but only for some moments or for one insert). -I did PURGE and AUDIT -I tried to copy paste in same instance of AutoCAD but that didn't work.
I'm usually using t least 2 instances of AutoCAD (I hope that is not the problem).
I am doing electrical drawings with the architect giving me an exported DWG from Vectorworks. I have XREF the background drawing that when opened is about 6 blocks of the building background and 2 blocks of the electrical devices.
Here is the problem: The architect sent me an updated DWG that only has the electrical updates without any backgrounds. My thought was to purge all and then select all the items and then copy with basepoint. Then open the original architects XREF drawing. Select those two electrical block, erase them (or move them to the size a fixed distance). Then paste as block from the other file. Then move the block to the correct location, explode, done.
Big problem: I just tons of this error in the command line referencing different block group numbers being ignored:
Duplicate definition of block Group-1265-1 ignored.
Then the block that was pasted added a background that wasn't in the old drawing and many of the items in that block was either missing or still had the old symbols. Can't figure out how to update the background with confidence that it is really updated with new information and not keeping old.
If I open a new drawing and paste that block in, everything comes in perfectly
We are a small company with two PCs - 1 laptop and a server. We are having problems using xref drawings across the network. The laptop is mapped to the Z drive and the reference file is on the server (D drive). Each time we open a drawing on the laptop (Z drive) the xref files which is saved on the server (D drive) cannot be seen. We reattached the file and it works fine until we closed and reopen the drawing. When the drawing is opened on the laptop the xref is not loaded on the screen. However, the file extension can be seen but no drawing is visible.
In summary how can we tell get the laptop to permanently reference xref files saved on the server without them dropping out?
When I receive my background drawings from an Architect who is basically exporting to DWG from their VectorWorks program I seem to have difficulty using their PaperSpace Sheets. Usually the border is a block so I just save the block as a file and then XREF it back in and then erase the block. From there it is a mess and can't figure out what is going on or how to fix it. First: I can't find any viewport to modify or scale, but if I click in the right spot I get multiple X-Y references as show in attatched file which are always scaled at 1:1 and as the 2nd attached picture shows is a location for three different viewports that I can't access. The attached picture is shown with the XREF backgrounds turned off so you can see the X-Y locations versus when they are on. How to actually make these in to editable viewports or at least erase them and start over?
We are using AutoCAD 2011 and AutoCAD 2012 on the same drawings. It is slowing the drawings down in AutoCAD 2011. There is at least one person that only has AutoCAD 2012 on their machine.
Is there any way to close a drawing that is open on another user's computer, from my computer?
We have a problem with engineers opening a drawing, printing and marking up that drawing, then taking the print to a drafter to make changes to the drawing, but failing to close the electronic drawing file.
Normally, we just call the engineer and ask them to close the drawing. If they were away from their desk, we could just walk over and close the drawing ourselves. Now that's not possible. We have a new security protocol which locks the user's computer after ten minutes of non-use. We each create our own password which we're not supposed to share with others. I just want to be able to log into the server and close a drawing that someone else has open.
