Nothing found on the face of it. Comment for your experiences

Hey everyone! I will try to keep this one short. I have a floor plan (2d plane), with some columns in it with different dimensions. I want to find the Center of Rotation of that particular floor using the command "MASSDROP".

I select the perimeter of the building, type "region" and then "mass drop" and auto cad finds the geometric center of mass (2d plane). I then move the CM to the origin, to set it to (0,0).

After that, I select the columns, let's say 9 per floor, and do the came thing but now for Moment of Inertia. I get the values with the command "massdop" but I get this message:

"Principal moments and X-Y directions about centroid:
I: 495.3251 along [0.9993 0.0382]"

That means that the Center of Rotation is [0.9993 0.0382] away from the Center of Mass at X,Y axes respectively?

Thank you in advance!

P.S. This is just a University project, NOT REAL LIFE BUILDING.

Hi, my question is if I can upload 3D models of lights to a map that people can use.

I am making 3D models of design lights, and I wanted to upload them to Autocad and SketchUp so architects and interior designers can click on a link and they can easily use those models on their modeling.

Is that possible? Or can you guys help me with a other solution?

Customer sent DXF I get "Error in drawing header on line 1. File is not valid DXF file. Invalid or incomplete DXF input--drawing discarded"

Does this happen because im on 2022 and they are 2024 version?

ive had several CAD jobs for the past 20 years, across several different disciplines (currently Architecture, started with E&I then piping ISO,), what i want to know, are classes people take for drafting teaching the real world use of autocad, Xref, Formatting borders and layouts for scale, i think i have worked with only 2 people that understood any of this. im self taught, my first E&I job was green, never used autocad in my life, they took me in and had one guy that was very good (but still limited in what he knew) got me started, 6 months later i was teaching him 3d modeling.
to the point, if anyone is willing to explain the things trained in classes (syllabus), i want to know whats missing for real work. im going to goto my local CC that has this class and talk to an instructor about improving classes so we can actually get competent drafters. im the only one at my job, that knows everything required to keep the business running. yes, even more that the owner, the most he does is hand draw plans. we need to hire another 1 or 2 people (yes im doing the work of 4), but i dont think anyone else i have worked with for the past decade knew enough to fake it.

Hello! I'm new to AutoCAD and I badly need some help with my first activity. I wanted to make this pattern inside of a 100x100 rectangle. The lines are 45° Diagonal and are offset to 10. The only problem I have with this is that the lines are intersecting just before it touches the sides of the rectangle. I wanted it to intersect on the side itself, I'm genuinely confused since the offset is 10 and the rectangle is actually a square so I was expecting that there wouldn't be any problem with this.

Edit: Just to be clear, the actuall offset value is really just 10, my only problem is the intersections.

Hey everyone I’m working on making a list of parts for making a PID. We want to make a list of every part and it’a description.

We have an excel sheet with all of the parts we use for every project we I have linked the excel sheet to a table in AutoCAD but I wander to be able to just copy or move the rows we need depending on the project.

Ideally I’d like to have almost a c lookup kinda thing.

Is this possible to do in cad?

My autocad can perfectly do a straight line using orthomode on before this. But somehow today even if i toggle the orthomode on the line is not straight anymore. And i cant find the solution on google

I cant attached a pic for you but i somehow look like the line below if you guys understand😅

Edit: got it! Thank you kind stranger 🥹

maybe i accidentally changed the view before this

Hey everyone. I’m using AutoCAD 2024 to create some 2D blueprints for my next house and I can’t figure out how to enable snapping to midpoints. I’ve used the built-in help function and tried moving my cursor from one endpoint to the other, then going to the middle, but CAD doesn’t show a snap point. Right now I’m having to draw a line from one end to the middle, use that endpoint for my new line, then delete it. Thanks!

A long time ago I stumbled across a post here that had some code examples for placing arbitrary text inside a closed polyline. I can't seem to find it and I'm looking for some inspiration on the best way to tackle this problem.

I know there are ways I can find the geometric center of a polyline and use that as an origin point, but for placing entities within the polyline this may fail on concave hulls. I'd also have to account for inner closed polylines (representing cutouts) to make sure the text doesn't land within them.

Anyone have any links to some examples to look over that will help with this problem?

Wondering if anyone knows a way to move/align objects using scale, but without changing the scale/size of the objects, only their insertion points.

When I go to print the dwg, program can’t fine aecstandard.stb. Where can I find the file and where do I place it in the program so I can print in b and w on plotter? Also, where do I put any hatch patterns I bought? Don’t show up in custom hatch?

Hello, all.

I have a .dim file, and I have a .dwg with a dimstyle i use often. I want to make a button on my toolbar that auto imports that dimstlye so that I dont have to manually set it up every time, but im lost as to what I need to do to achieve this.

Any help is appreciated!

Morning all, hopefully, someone can help.

Recently migrated to a new work machine, and I've reinstalled AutoCAD LT. It's hard to pinpoint exactly what's wrong with the text, but it is blurry. I can read everything else fine, PDFs, Chrome, emails, etc, but the actual program text looks like it's operating at a lesser resolution.

I've tried taking a screenshot but it's not giving the full picture. Side by side I can tell it's more blurry, the screenshot doesn't do it justice.

Has anyone had this before? I've tried googling, most if not all of the info relates to certain files or plotting to PDF.

Very new to AutoLISP and am trying some simple things with it.

Trying to use a lisp to set the layer of the first object, offset it a certain amount, and set this new object to a certain layer, then draw in the miter lines between the corners of these 2 objects.

What would I add to the code for the miter lines?

(Defun C:setandoffset (/ p1 ob1)

(command "_.chprop" (setq ob1 (entsel)) "" "_layer" "Frame" ""

"_.offset" 1.1401 ob1 (setq p1 (getpoint)) ""

"_.chprop" "_last" "" "_layer" "Glass" ""

); command

(princ)

);

I used AutoCAD for many years and am trying to pick up side jobs but I have lost the ability to use my left arm and hand. I have always used my left hand for shift etc. and I can't figure out a work around. Does anyone have any tips? Thank you in advance.

I'm a beginner hitting up against a strange issue and I'm hoping someone has a tip to help figure this out.

When I'm in a layout of my drawing and try panning to center a different view in the viewport, the "new" view is copying and superimposing itself right on top of the "old view."

I'm really just trying to "reframe" the drawing, not superimpose it. Is there a box somewhere in settings that I need to uncheck? Many thanks!

So Microsoft word has an option for words to wrap around objects, images, etc. is there any option for that in AutoCAD?

So I’m a CAD drafter at my company but our administration team who don’t have Autocad but have Autodesk Design Review so that they have access to DWF files for printing are not showing the centerline symbol on their prints.

Does anyone know what the symbol code is that they need to download (and preferably where they need to download it from) so that we can eliminate this issue?

Thanks in advance.

Hello all,
I have a user with ACAD LT 2024. They have dynamic input turned on, but they can't see dimension preview. Is there a variable or something that needs to be turned on for this? I have other users with the same year who don't have this problem...

The dimension preview I am referring to is the one that pops up when you highlight over the endpoint of a line or another vertex in a polyline.

Below is what I’ve found from my job on organization. Is this what you use? Or do you use a different format/numbering system?

01 - Civil

02 - Landscaping

03 - Architectural

04 - Structural

05 - Mechanical

06 - Electrical

07 - Plumbing

08 - Signage

09 - Technology

10 - Fire Alarm

11 - Demolition

12 - Misc Notes & Drawings

13 - Interior

14 - Field Drawings

So this has been bothering me for some time, but finally fed up and trying to figure an actual solution.

When publishing the FIRST time, it goes through A-ok. But after that initial one, it always sends WARNING: Incompatible or missing plot style. After this, I resort to PLOT command each individual page as a work around.

Please help.

I draw custom homes, and until now have always worked in 2D. I've started playing around with 3D for some of my more complex designs, but I'm struggling with the curved shapes. Right now I've used solids to create the house, and have been playing with surfaces and solids to try and reflect the ground outside. It's a walkout basement with a smooth slope from the front to the back of the house. I can get the basic shape using boxes and wedges, but it's obviously not a smooth hill.

How can I get a more rounded, realistic shape?

Hi mates. I'm trying to get information out of a Navisworks file, but the model is georeferenced. The steps to get a DWG are NWD (Navisworks) > FBX (3ds max) > DWG. But as the model is georeferenced, 3ds has some trouble rendering almost anything that far from the origin, and I don't want to lose the coordinates.

Is there another program to export FBX to DWG??

Thanks in advance!

I am working on a very large project.

I will soon be creating a drawing that will have about 2,000 to 4,000 blocks per floor. ( IT. ) And multiple floors.

Each block will require to have a minimum of Block number / item type acronym. ( sequential numbering )

• ideally each block also has attributes that do not need to be in the plan but updated manually per block and shown in a dynamic table. This entails about 8 codes such as:

Item height/ function/ tem code, sub-codes

The drawing will change multiple times, so I would like to be able to add/ remove blocks, and reset the numbering and update the overall quantities.

I am concerned about file size and trying to reduce re-work workload

Any suggestions for a strong startup strategy ?

( if using autocad elec rather then arch might be better, that is also an option )

Primarily grain storage in the form of various sizes, shapes, and types of bins. Also conveyors and structures. I have a full version of AutoCAD that I've been using but only to create 2D layouts from elevation and overhead views.

If you wanted to turn a layout into a 3D model, with steel texturing and paint shown, is there a better software option to use? I'm decent on a good day with Solidworks, but it's a pain to build a grain bin model in since the only CAD blocks I have are 2D.

I need to use different layers (wall, door, window) when drawing the internal contour of a building. Is there a way to avoid having to interrupt the line drawing to change the layer?

The company I work for has a LISP app written (by someone who has since left) that automates a BOM creation. It works fine, but there have been issues where a user has simply hit space or enter immediately after running it, which obviously runs the command again.

I intend to dig into the app and update the code to prevent these issues, but until I can get the time to debug a couple of thousand lines of code, I was hoping for a quick fix by simply preventing the AutoCAD repeat command feature when hitting space/enter/right click, but only for this LISP. I do not want to affect the behaviour globally.

Is this even possible?

Afternoon, just wanted to ask what the process of exporting an DWF to DWG from Design Review? I've been told it's something that can be done, but not how.

Does anyone else use FireCAD here? The dev is always releasing updates, but inevitably breaks something new with every fix. It's more of a hiccup than anything, but some of them are really annoying. One thing that hasn't been addressed is that whenever I use the Draw Circuit Wirepath --> Delete segments option, it will often delete polylines for my walls. This is due to having my fire alarm devices snapped to a wall or intersecting a polyline.

For background, there is also a "reuse" option instead of deleting the wirepaths (which are polylines), but sometimes you need to delete to eliminate duplicates or messed up segments. I tried locking my wall layers, but even then I've had some disappear. This post will be crossposted in r/firealarms
