I used to use Nanocad and just recently started using Autocad again. I sent a .dwg file to an engineer which is a drawing I had started in Nanocad and then imported and finished in Autocad 18 and he says he can't upload it. He says he gets a fatal error. Even though I saved the file as an AutocadLT 2013 format from the file save menu. I really would like to know if there is any Autocad or AutocadLT user with Architectural experience I could send a sample drawing to or can try the attached file so I can determine if the problem is really with my files or with the program or method the engineer is using to try to upload my drawing when I email it. Any assistance would be greatly appreciated. Thanks, PCS electrical FINAL ACADlite2013.dwg

Hello, Where I work we use a 0.25 arc length min and max. Whenever I get into a revision drawing for the first time, I am always having to resize the arc length no matter what. Why is this not something that can remain constant? I have to specify it on every sheet I work in. Is there a way to globally change this and have it be set every time? Is this something that the prototype drawing needs changed? If so, what is it?

Greetings, everyone ! May I introduce myself a bit : I'm Gauvain Boiché, I'm currently studying Video Games in Belgium. I am now in an internship in a small company. We usually use 3DS Max 2017 for modelling, but now I'm struggling on a problem, as I have to use AutoCAD 2018. And I am totally lost. To be honest, I'm not intended to use AutoCAD after that, so this is really a one-shot of despair It is for a very-very small problem. We have to sell some of my products for a bigger company, but they are asking it in DWG. And I have to convert my FBXes with Material IDs to DWG, with the good colors, to Revit. We found a "good" tutorial about it, here : Long story short : I don't speak Spanish ( or Portugese ) and the shower is not telling anything I can understand. Probably he is using a shortcut I can't translate. He lost me at 5:10 in the video. I managed to re-organize my workspace, which looks like this : http://i.imgur.com/IMhfktT.png Now, I'm really struggling, and I have basically no time to just learn about AutoCAD, and not even Revit then. So, my question is : - How did he select point on the object, bypassing in the process the unwanted ones ? And, to be shorter, if you know any way to just export an object from 3DS Max with material IDs and good color directly to Revit, I would be eternally grateful Thank you in advance for your time !

Guys, I had to re-scale a drawing and convert it to DXF so we can use in our cutting machine. The problem is when I try to open the DXF file on our factory computer there are missing some lines. But when I open the file on my computer, it is perfect. Do you guys now if this is a AutoCAD error when converting the file to DXF or its a problem with our factory's computer ?

G'day all I'm working on and editing a mapping project from photogrammetry. I have a block which indicates a square manhole cover. (File is attached to this post) My project area has hundreds of these manholes and my client needs each of them scaled and rotated to fit the exact size of the manhole. I had been manually doing this with the help of an ECW image in the background. But the process is rather tedious and not all that accurate. My operators can pick up a three point string showing the height and length of the manhole. Some manholes are square and some are rectangular. I have a few lisp routines that get the block in there. The block insertion point comes in at the first plotted point as required. Is there any similar LISP that will insert the attached block dwg file at the first point collected and scale it based on the 2nd and third point whilst keeping the elevation heights? I've attached two dwg files... One is the block itself and one is a diagram with a better explanation. I've also added a screen shot of what is required. Any help would be appreciated Cheers guys Manhole.dwg BlockSample.dwg

I'm working on a building a helmet, and I have completed a basic 3d model to help me visualize how I will build it. But I don't know how to flatten out a cone. the helm is made out of 5 pieces, a top, a top side piece and a bottom side(the sides are fabricated twice to make a full helm) I have a problem with the top sides and making them a flat layout.

Hi friends, this is my first post here . I am relatively new to Autocad MEP . I recently got a job as Mechanical Engineer in an HVAC design and installation firm in a junior level, and I need to practice before joining. I tried learning the software by my own through youtube and several of my doubts have cleared through google. But some things cannot be solved by google search and hence I have arrived here. I have taken the autocad 2d plan of my own house from my Dad , and started practicing drawing and sizing the ducts . I have attached the dwg file here : Final file - https://www.dropbox.com/s/84lqro3b701m6lk/mukatra.dwg?dl=0 Used for Xref ground floor plan- https://www.dropbox.com/s/x8e241aat9pukye/Mukkatra%20mep%20ground.dwg?dl=0 Used for Xref first floor plan- https://www.dropbox.com/s/rqfe5xoyxwhe8r2/Mukkatra%20mep%20first.dwg?dl=0 These are my doubts: 1) I wish to know my duct modelling method is correct or not . I roughly estimated the flowrate required for each room , divided it by the number of diffusers that I wish to place , got the flow rate for each diffuser and assigned it to each diffuser after placing them in a room.I followed this step for all rooms . Then I started the duct drawing . I chose 2 line duct method and started from the major trunk , selected all diffusers of the same floor , got total flow rate and and duct size was obtained (medium pressure lane - velocity around 5m/s). Is this the right method ? 2) I roughly placed the diffusers just to practice drafting. In the professional way, how to place them at particular distance from walls? I know the array function only . May be this question is dump ,but trust me I am new to Autocad thts why. 3) I have assigned different layers for each floor , ie blue for ground floor ducts and red for 1st floor ducts. This was done hoping that I can hide them when needed to take print out . Sorry for my stupid idea , plz tell me which is the real method to take prints in 2d for each floor separately . 4) While taking the 2d view after hiding all other floors , some of my ducts and connectors are partially visible . Its like if some portion got erased with an eraser partially. How to fix this ? 5) This one might be the stupidest of all. Does layer color come in printout ? If I choose light green , Its barely visible ? like that? or all comes in black ? 6) In the schedule table , which I plan to create consisting of duct length and duct size , I wish to give them a series-name or tag . And I need these tags to appear in the drawing on each ducts or very near it. I have no idea how to create tags for ducts. I can only see tags for air terminals and some other stuffs. I need tags for all the things in my drawing. My wish is to make the drawing easy to understand. A simple numbering over the ducts or equipment will be enough . I will sort and group them in scheduling table. 7) Some say , autocad 2d is used for hvac drafting in most companies . Why dont they use Autocad MEP ? The standard library of autocad mep doesnt match with SMACNA standards? Or is it the difficulty to create custom equipment in the library ? Or is it the fact that even if we make in 3d , the printout will be always in 2d ? All the features in autocad 2d can be done in 3d anyway right? Is it possible to change the diameter of an air terminal like diffuser in our list of diffusers ? I know they have different diameters or l x b , but I wish to knw the method for modifying it. When I googled , I saw a big tough method to import a library list or something like this and copy the default list etc etc . I just need to create a new diffuser with a custom diameter with the existing design, possible ? 9) Usually , is schedule table printed along with the plan ? or is it just exported to excel and taken print ? Can the method of scheduling used to create bill of materials in excel ? Is this feature available in autocad 2d? This is a great advantage over autocad 2d? 10) The formula used in duct sizer is the same as the one in autocad mep right? duct sizer uses the simple formula - q= vA and darcy weibash equation right? the same with autocad right? 11) After I drafted , I didnt right click on my duct and choose - 'calculate duct sizes'. Since I had already sized the duct accordingly when drafting by the method described in point -1 . In the analysis tab - view by friction option was there. I was curious and tried it . But the all ducts were green in color despite I saw the duct friction loss higher than 0.7pa/m . Green was supposed to be Out of these questions , I wish to know about the right method to take print (mentioned in doubt 3) for duct plan in each floor separately and doubt 6 is very urgent and consumed my entire day. Please understand that I have been learning this for a week now by my own and many of my questions might be silly for you. The tutorials available in youtube is very less compared to some other software such as solidworks , catia , ansys or abaqus etc . So , each doubt takes a lot of time searching !! Please help guyz , Ill be really grateful . When I become expert in autocad , i will also be helping the new people , but I should master it first

Hi, I am an Electrical Engineer and I am drawing lighting plan on autocad. Can anybody do like this wiring lisp ?

while browsing the interwebs the other day i came across a few pages talking about using gaming keyboards and mice in conjunction with autocad. so i did a little bit of reading/research (things are slow at work) and found out it wasn't to difficult to do, and a new mouse was like $80. i thought why not give it a try. i took to amazon to get the logitech G600 for $49 w/prime shipping, i received it monday and tuesday i was off and running. the most difficult thing about it was choosing what commands to program on the thumb keys. it has the normal two mouse buttons and scroll wheel up, down, left and right, with third mouse button as a "shift key" for the 12 thumb buttons to make 24 individual keys, plus two other buttons with the scroll wheel that i believe select between profiles you can set. (haven't dove completely into it) after working with it for the better part of tuesday, this morning wednesday i reconfigured some commands on the thumb pad and printed out a cheat sheet to memorize. some of the commands like copy/past/cut work outside of Autocad which is a plus. it has helped in some areas of accuracy typing commands like move between 2 points (i mistype a lot) but slowed other processes down just because its new and still getting to the nuances of operation. i believe it will become second nature as long as i don't change the commands often as i feel which ones fit best or needed more. anyways i thought i would just throw this out there maybe it's something you would like to try or have some experience with or didn't know you could use. let me know if there is something else out there you have tried to work with. links: http://www.lifehacker.com.au/2015/05/why-i-started-using-gaming-peripherals-to-get-real-work-done/ http://blog.grabcad.com/blog/2010/08/28/best-for-cad-work-mouse-trackball-3d-device/ https://www.amazon.com/Logitech-G600-Gaming-Mouse-Black/dp/B0086UK7IQ/ref=sr_1_sc_1?ie=UTF8&qid=1486577758&sr=8-1-spell&keywords=logitehc+g600

Hello, guys! I need a lisp to rename the current open file. I already have a routine that takes the current file name and creates a string with the new file name (Just six numbers in the old name needs to change)...

Hi... I have a problem with the ObjectARX 2017 project creation on the Visual Studio 2015. I've downloaded the ObjectARX package from the Autodesk page and run it. It was unpacked in that folder: C:\Autodesk\Autodesk_ObjectARX_2017_Win_64_and_32_Bit. But there aren't any executable for the installation there. I've downloaded too a small utility called 'ObjectARXWizards', and run it. This programm ask me where is located the ObjectARX folder and AutoCAD folder, and after this, install the package. In that moment appear in the control panel appear in the VS2015, at the Visual C++ tab the Autodesk, with two options of ObjectARX project modelos: ObjectARX/DBX Project and ObjectARX/DBX/OMF Project. When I select any of these two project options, it give me a error like this: Creating project 'ArxProject1'... project creation failed. I did run the Visual Studio as administrator, from a user with administrator privilegies, with the UAC turned off and install using ObjectARX Wizard, but the project creation on the Visual Studio still not working. Always give me the same error. I really don't know what I need to do to work with. Anybody can help me?
