Not sure for ZWCAD, but it Tamil font installed on your computer, you should be able to access it if it is

in autocad i need to place block which was align in x scale i have lisp code too but the isseu is the block is placing wrongly i was place mid chainage of the point where i need to place those block but always it placing wrongly l;ike first length of my block is 12m but the code placing 8m 4 m each side i was attached all the input i have can anyone fix this Drawing2.dwg block.dwg PIPE_PlotBlocksFromCSV.lsp PIPE_Block.csv.xls.csv Book1.xlsx

@mhuppIt's like this For example , I have layer 1, layer 2 , layer 3 And I want to select layers 1 and 2, add them to the newgroup filter, and name it something like "architect".

I NEED TO TYPE TAMIL FONT HOW TO DO IN ZWCAD

As I mentioned already, AutoCAD Architecture is FREE with the Toolset. All you need to do is download it. Architecture Toolset in Autodesk AutoCAD | Features This looks like something Bricscad should incorporate as well. That's the reason I stopped working on the LISP, but I will probably try to get it finished up anyway.

Thanks for sharing that and testing it. I’m currently using AutoCAD 2026 (standard), and from what I can see, the AECLINEWORKSHRINKWRAP functionality isn’t available in this version. It looks like it’s part of the Architecture/Civil toolsets, so accessing it would mean moving to something like Civil 3D or the AEC Collection, which is quite a big upgrade just to use this specific functionality. Really appreciate you taking the time to test it though.

Thanks for pointing that out — I gave it a try on the same drawing. It actually handled the case surprisingly well and produced a clean outer boundary for the full shape, even with the gaps and more complex areas where the other approaches were struggling. Sharing the result here.

Like @SLW210 I think you would be better off with a Windows Intel PC. Other CAD software that has MAC software is often reported as having niggly problems. Until there is a true MAC OS based say Autocad those problems may continue, in saying that there are some true MAC CAD programs out there. Autocad MAC has existed for like 30 years and still no true native version.

"Doing this manually for 2 hours is insane for production workflows. I developed an AutoLISP solution that automates this. It bypasses the convex hull limitation and extracts the true concave perimeter from COGO points in 1 second. It's packaged in the Todo Terreno CAD Suite on the Autodesk App Store (first month is free). Command is TTC_POLY-PERIMETER. Optimize your time!"

Are you talking about layer states?

I really need a LISP program to select layers into Layer Filters and name this filter group. Please help me. Thank you!

@SLW210 Here you go. https://forum.bricsys.com/discussion/40003/extract-outer-boundary-of-2d-drawing#latest

You have to purchase Civil 3D, Architecture is free with AutoCAD. OP still hasn't stated what CAD they are using.

$119 USD, you get 15 day free trial. Most examples didn't show gaps, but looks like the user guide claims Auto Tolerance and Auto island detection. Could you link the discussion on Bricscad for the OP?

AutoCAD for Windows has more features than AutoCAD for Mac. Compare Features: AutoCAD for Windows against AutoCAD for Mac

I think this is the product BIGAL was referring to.https://engenext.com/pages/egboundary.html I have no affiliation to this product, I just remember seeing it discussed on the Bricscad forum.

Thanks for all the suggestions, really appreciate you taking the time to look into this. I tried a few of the approaches mentioned — they seem to work quite well on cleaner geometry, but in cases like mine with small gaps and more complex connections, I’m still seeing partial or inconsistent boundaries being generated. I’ve attached a simplified sample from one of my project drawings. This represents the kind of geometry I’m dealing with, where standard methods haven’t been giving consistent results. Curious to see how your approaches handle this case. Engine Part Assembly.dwg

Hi everyone, I’m starting my Mechanical Engineering degree this fall. I want to practice AutoCAD a bit before starting and get a basic understanding of it. I want to buy a laptop with a budget of 2,000-3,000 USD. I am currently looking at the MacBook Pro with the M5 chip and 32GB of RAM. I've seen that it recently beaten RTX5090 GPU in blender and I've heard a lot of praise fot Unified Memory, but I’m concerned about how that translates to a professional engineering workflow, specifically for: AutoCAD: I plan to do both 2D drafting and 3D modeling. I know a native macOS version exists, but are there critical missing features compared to the Windows version? I'm thinking about choosing between Mac Pro M5 or a Windows Workstation/Gaming Laptop with a discrete RTX 50-series GPU. I’d love to hear from anyone who has used Macs for AutoCAD or from Windows users who used a discrete GPU setup. Is the M5’s power enough for AutoCAD and if 32GB RAM is good for basic 3D, or should I just stick to a native Windows machine? Thanks in advance!

@SLW210 CIV3D has Shrinkwrap also. Pity they did not include for plain Acad. If you can work out which dll or ARX may be able to copy correct files to plain Acad. As "TotalBoundary " is no longer available there was a post for a similar product may have been here or at Forums/Autodesk. I remember asking how much but did not get an answer. Try googling.

I think I have a solution but would need a test drawing.

I did find this... Lisp to create a boundary around blocks that are not touching. - AutoLISP, Visual LISP & DCL - AutoCAD Forums I should have also mentioned that AutoCAD Architecture FREE toolset has the AECLINEWORKSHRINKWRAP command.

I moved your thread to the AutoLISP, Visual LISP & DCL Forum. Please post in the correct forum.

I had to stop on the newer version yesterday due to my "paid" for work, still debugging it. Can you post an actual .dwg of that example for testing? Also, what version of AutoCAD are you using?

Here’s a sample of the kind of drawing I’m working with. It has dense geometry with small gaps and overlapping elements, and in cases like this, standard boundary methods don’t always produce consistent results. This is the type of scenario I’ve been trying to handle more reliably. I tried this on one of my actual project drawings. The image shows the input geometry and the output generated using the suggested approach (blue lines indicate the generated boundaries). It works quite well in simpler cases, but for this type of geometry I’m still seeing partial or inconsistent boundaries being created — it’s not forming a single clean outer boundary for the full shape. This is the kind of scenario I’ve been struggling with, especially where there are small gaps or more complex connections.
