I’m a new user and have still a lot to learn. As with any new tool, Scetchup requires some time to learn, and while I’ve managed to resolve most of the issues (thus far) with the help of posts and YouTube instructions, I haven’t been able to deal with a few rather annoying and recurring problems, regaridng lines not building surfaces. I know that there is alot of posts out htere but I have gone through so many of htem and haven’t found the root of the problems.
In atached design, I have checked that there are no discontinuities or hidden objects there and that the lines are each on the correct surface (using shift while drawing them). Adding diagonals makes the form build a surface, but I can’t see where the problem is (see figure. I’m trying to make the roof create a surface).
Another annoying issue I’ve encountered (not always) is that when I make a horizontal line and two vertical lines that cut the horizontal line, I can’t add another horizontal line to the vertical ones at another height. It works Many times, but occasionally, I see a tiny gap between the vertical and horizontal line on an edge that should supposedly cut the other line at a 90-degree angle. I’m unsure if I’m doing something wrong or if there are precision issues that can be solved by adjusting the snapping parameter (by the way, how can I change that?)
I would genuinely appreciate it if someone could explain the issue.
Can you share that model? the ~ means that the measure is not exact. Try to increase the decimals showed. (Window->Model info->Units) and untick Snap Length.
Many thanks for your reply. Now, I know how to adjust the precision. Unfortunately, the problem hasn’t disappeared, and I can’t close the roof as an area.
Also, when I try to draw a line parallel to the roof line on the base level, it somehow shows an additioanl area (see a blue area in the pictures below) from another tag. Do you know how I can dissconnect the two tags? Which could be a reason that the area dosen’t closeWould much appreciate
Many thanks again for your help, which is genuinely appreciated. It clarifies a lot. However, I’ve tried hard to choose the correct endpoints and used the shift button to ensure my line is on the surface.
I had assumed that when I’m trying to use an endpoint as my starting point for a line, Scetchup activates that exact endpoint, while it seems like that endpoint can be close to the targeted endpoint but not necessarily the actual one. I have even tried to lasso-select any objects near the endpoints that I can’t see, and if found, I’ve deleted them. However, it seems like somehow the software finds some additional endpoints to connect to, rahter than the one that is visible and activated by the mouse. Is there a way to ensure that I’ve chosen the intended endpoint?
Another problem is that, as you can see in my file, the scale is tens of meters, while the gaps you’ve identified are in millimetres, which makes it very difficult to check for visually. Are there other ways to find out if there are gaps in the drawing without needing to zoom in 100 times?
I have checked some essential courses online, but I haven’t been able to resolve the issues I mentioned above. Do you know of any online course that covers these issues?
Here is a small video. The CAD file you have imported has a lot of errors and extra lines. There are many ways to start with a CAD file but maybe this will help you.
Wow, thank you so much. this really helps and I’ve laready learned a lot. Many thnak again for your help.
If I may ask, in certain cases two groups of objects from differnet tags share a line or more. In my case for example, the garage share a wall (a line) with the main building. Is there a way to automatically identify shared lines (or objects) among the tags, liek with a specific colour or pattern or thickness?
When you group objects, lines are on both groups but you only see one of them.
It’s important not tagging edges or faces, only groups or components. If you don’t do that you’ll have lots of visualization problems, ence try to group edges and faces as soon as possible. If you rename each group you will save time later.
