Autocad Simple

[Aide Broeckel]

Thedrawing is a very simple line drawing, 97kb in size. Every 3rd or 4th action caused the program to Stall, a dimension take minimum 20 seconds to complete. Panning or Zooming Stalls it. I have all the latest updates installed. When I installed 2020 I optioned to copy the 2018 settings.

In short, the simplest tasks are hard to do because it takes too long and is really affecting productivity. It feels like torture just to hatch a few walls... Other software runs smoothly, even the heaviest Photoshop file runs fine but the smallest and lightest DWG file on AutoCAD runs as if it's 100MB.

I have noticed that it's most inefficient when working on server files. Even when I'm on a local file with a server file that's open. It's worse when the internet goes down and there's a server file that's open, I can't even access the local dwg when that happens, the whole software freezes.

Can you describe the situation a bit more, is LT installed on your machine with just files being accessed over the internet? Is this a company setup. The more information you can give will maybe let someone with a similar situation recognise where the problem might be.

I'm back in the office and this is a new PC so I found it extremely odd and frustrating when hatching simple items would cause it to lag (up to 2 seconds is the norm on this PC and sometimes even longer) when the older laptop I was using ran smoothly with acceptable lags (less than a millisecond and usually not more than 2 seconds)

I have a simple block which I want to make have a vertical exaggeration of 10x whatever distance I set as the distance parameter. For example, if I put in a distance of 2 for my distance attribute, the block should have a depth of 20.

It does make sense, sort of, you start with a block that is 1 unit long and you stretch it to 2 units, but you are only stretching it 1 unit further, and it is that 1 unit that gets multiplied by 10 (so 10+1). The original part 1 unit long isn't altered. Try the attached version, the original is 10 units and the action only works on the last bit.

Thanks for the reply! This is what I'm looking for. I understand your explanation of how my block worked out that way, but I'm having a bit of trouble understanding how your block works for that. Now that it's 10 units, but the stretch distance only applies to 1 unit, wouldn't it be something like 10*1for the stretch +9 for the rest of the block to = 19? I probably misunderstand how the stretch applies to the block? Thanks again!

The stretch doesn't 'apply' to 1 unit, the stretch applies to the vertices or objects within the stretch window and with the distance multiplier of 10, it stretches them 10 units for every 1 unit the parameter is moved. The same stretch would apply even if the window enclosed 9.999 units of the linework.

The linework in the updated block is initially 10 and the parameter is initially 1. If the parameter is stretched 1unit with a distance multiplier of 10, then the linework is stretched 10 units. Your initial issue is that your parameter and linework did not start with the 1:10 ratio and so it was off. The updated block does start with that ratio and so it works.

I created 2 distance parameters, a ground surface distance parameter which stretches the casing height parameter down to simulate sea level, and then my Casing height parameter stretches my casing. This works, except that my casing becomes a height of 10 (original height)+5, instead of just having a height of 5. How do I go about making my casing height the difference only?

Your description/explanation was very confusing but I believe that the attached file gives the relationships you require. You will have to adapt the concept to your needs. Distance A and Distance B have grips and you can input their respective values. Distance 'Diff' is always going to be the difference between them. Distance '10X Diff' will always be 10X the difference between A and B.

I believe that the attached file is what you are looking for. Once the values for 'Ground-Surface' and 'Casing-Height' are entered, the difference is shown as the upper cyan line and the height is 10X the units of the difference. If the Casing-height is a larger number than the Ground-Surface, then the height is positive. If it is smaller, the height is negative. The dimension is added just as an easy visual check that it is working.

Here's an explanation of the workings of the block. The 'ground-surface' parameter operates a stretch action to move the bottom of the 'difference' parameter. The 'casing-height' parameter operates a stretch action that moves the top of the 'difference'. Because of this, the 'difference' parameter will always equal the difference between the 'ground-surface' and 'casing-height'. The 'difference' parameter is chained so when it is stretched, any action that is associated with the stretched point is executed. There are two actions associated with the 'difference' parameter. The 'stretch 10x top' action is associated with the top point (which is moved by casing-height) with a distance multiplier of 10x. The action's stretch window is around the top of the cyan linework. The other action, 'stretch 10x bottom 180', is associated with the bottom point (moved by ground-durface) and similarly has a distance multiplier of 10X. Its window also surrounds the top of the cyan linework. It additionally has an 'angle offset' of 180 degrees. The result is that when ground surface moves down (increasing the length of 'difference), the cyan linework is stretched up so that it also increases.

There are relatively few drawbacks to this product, but the complaints mentioned by users include difficulty in texturing and slow support. Customer support is, of course, understandable since it is a free program, and the people assisting you are other users when they have time, rather than a paid employee. Still, the texturing issue is something to keep in mind if you need it for your designs.

This simple design program is open source and can be used for both 2D and 3D computer-aided design. SolveSpace has many features useful to those who work with CAD. It can handle extrudes and revolves and is also exportable. Most importantly, it can add holes in designs. You can specify the size of the holes, make sure they are level with each other on parts that require them, and move them apart. This feature is critical for those using 3D printers to build pieces that need to be put together and is always a useful addition to any software.

LibreCAD can be saved to various file types, which is essential for sharing the data with team members and customers. It can be read as a DXF file and can save as SVG, JPG, PNG, and PDF, among other types of files. LibreCAD has some tools that make it useful for 2D design, including basic tools such as lines and circles, as well as the ability to create layers for easy fixes to your model. LibreCAD is also open source, making it highly adaptable to individual needs.

To top it all off, LibreCAD is a lightweight program that takes up very little space on your computer, leading to fast loading times and a program that runs well, even on older programs.This program is specifically designed for industrial designers and has a rich community striving to make the program better with add-ons, extra features, and multiple languages. You can also receive help from the community in those languages, making it one of the best global 2D CAD programs available.

It also allows a lot more than many other free programs. You can create animations, lighting effects, and even textures. SketchUp Free is an excellent choice for 2D and 3D modeling, especially for those practicing for a career in animation since very few free programs can do texturing or animation as SketchUp Free can.

This program is designed specifically for use with 3D printers. For engineers more used to the typical toolset provided by other CAD software, this one may be a bit of a shock. For those who find standard CAD software confusing, however, 3D Slash is a lot of fun. Initially inspired by Minecraft, the creator realized that kids playing Minecraft quickly and easily produce 3D models. Some of these models were, in fact, very advanced.

He took inspiration from the ease with which children could 3D model with this program and made an actual 3D modeling program based on the same principles. To create a model, you use cube shapes to manipulate them. Tools such as hammers, trowels, and chisels change the shape, remove, or add the cubes. These tools are naturally intuitive, and you can begin creating models with some degree of skill after just a little bit of experimentation.

The Russian company NanoSoft designs NanoCAD. Their program is free to download and has no catch. Instead, they make their money through add-ons you can purchase if you so desire, none of which are required for the functionality of the product. When you first download the product, you receive a demo version, which will have a watermark for NanoSoft on the product. To get a professional version free for any use, you have to register the product with your name and a valid email address. NanoSoft will then send you the full version free.

NanoCAD comes with a range of impressive features that make it an excellent CAD software, including quick selection tools, integration with other CAD software so product ideas can easily be edited, and a wide selection of editing tools. The most up-to-date version of the software includes Direct X support, which is useful for those who use CAD software for video games, as well as being a practical addition to most developers. NanoCAD has been thoroughly designed and is a great free alternative to AutoCAD. This one may be our top recommendation for general use.

This program brings 3D modeling to a whole different level with all its unique features. Designed for advanced users, those who are new to CAD may struggle with the learning curve. While it may take a while to learn this program, it features 3D modeling like no other. Not only can it handle all the basics in 3D modeling, but it also has features that allow for a liquid effect, and you can reuse objects in your render to help save time.
