Are you working with a 3D model? Here’s a video I found importing 3D elements into AMADA AP100. I think the source program was Creo in the video but the video sheds some light on the export-import process.

Also, I forgot to mention, if it’s only slowing down on specific drawing files, try using the Purge and Overkill commands on the whole drawing. Purge takes away any blocks or drawing elements that aren’t actually used on the drawing and Overkill combines any similar, overlapping lines.

SketchUp doesn’t have built-in rendering tools so you’ll have to use third-party apps. My favorites are V-Ray and Lumion.

There’s also something to be said about using SketchUp’s built-in Style tools and just post-editing on Photoshop. Here’s a site that has a bunch of good tutorials on these: https://visualizingarchitecture.com/tutorials/

The closest things I could find that might be helpful to you were these videos:

1. For StarCAM CAD 4.4 so it should somewhat be similar to your 4.5 one
2. These ones are from the same uploader and seem to be in Chinese. If the interfaces are similar to your English version though, you should be able to follow along.

Once you get used to using any CAD program, you develop your own preferred workflow. I know some who prefer making individual drawings and then putting them together as an assembly afterward but also know others who do all assembly parts in one drawing.

I personally prefer working with individual files for all the parts (cleaner that way). It’s good to pay attention to universal coordinates when doing this though, i.e. make sure all your files have a common reference origin point, since that makes it much easier to insert all the pieces together in one assembly file at the end of the process.

Most websites where you can share your CAD files are usually public and free, so I think your best bet might be to make your own website for these.

Shopify.com is usually a good place to start if you’re thinking about e-commerce and digital shopkeeping.

AutoCAD encounters graphical issues like this when you’re zoomed in too much. You can try typing in “REGEN” with your shapes on-screen and see if that helps.

Working with external references is always trick with AutoCAD so I know how frustrating these little nuances can be. I suggest checking out the layers in both the file you’re working on as well as the original referenced file. If a line is under the Defpoints layer, it sometimes won’t be visible when printed. Try to tweak the layer settings if that’s the case or just assign the lines a new visible layer.

Try a clean reinstall of the program. If that doesn’t work, you might want to get your machine checked. It might be an issue with the RAM or possibly the battery.

You can try these 2 solutions:

1. Type in LTS to edit the linetype scale and set it to a different value. Going for a low value might fix it but try going for a higher one as well to cover your bases.
2. Check that the insulation line’s properties aren’t set to ByLayer or ByBlock. If they are, the linetype settings of the Layer/Block that the insulation line is part of might be overriding the linetype that you see on screen.
