It's Friday evening in New Zealand so I'm taking a little time out to list my top 20 Feature Requests
1) A few different line weights could be added (and ensure they are exported to PDF and Layout properly.) this could be done through the layers palette in the same way that Colors are handled. Or a component/group could be assigned a line weight. Or lineweights could be mappd using colours (similar to Autocad) so red = 1pt, blue = 2pt....there are many options.
2) Export scenes to PDFs: a better scene export dialog box (maybe use Scene Manager to select and export scenes) should allow more functions such as renaming multiple scenes, copy & paste scenes between models (there's an extension for this), have an option so that scenes don't automatically display new layers.
3) Daylight savings time check box, How many times did I not realise that this wasn't being changed, and ended up showing a 3pm shadow that was actually a 4pm shadow?
4) Import and Export with basepoint (or 'origin') should be possible in a way that allows me to model even though the origin of imported entities is 100s of km away (which is often the case if you work with coordianted data in a local or natuonal grid system)- If i import a DWG with a known cadastral system and the basepoint happens to be 100s of Km away, I have to shift it otherwise the model warps when viewing. I'd like to model in sketchup without altering the basepoint, so that when I export the model the basepoint is intact.....otherwise a surveyor/engineer risks importing my model to the wrong coordinates. So, the model needs to remember where XYZ is referenced. Surely trimble has a tool for this! (and I dont mean "use TBC")
5) Fix the Components and Materials browsers so they don't default to the original file path and force me to "open local collection" every time. (yes, I have mapped my file path properly in my template). Also fix the amount of time it takes to load a component/material menu - it takes at least a few seconds but this is frustratingly long -when you're flicking through numerous folders - does it not make a local cache of thumbnails & meta data?
6) PDF export with line weight options (default 1pt is usually too thick for technical drawings).
7) a way to eliminate all components & materials not created by Pro users (no offence to non pro users but your components are usually terrible). Alternatively if somebody competent can give good components/models a badge of "professional-ness", that would be OK as a filter.
8) basic animations..I mean just rotate, move & scale.
9) camera path animation and more options for scene transitions (eg like google earth tours where the transition starts off slowly, speeds up then comes to a slow stop)
10) ensuring materials edited using the sketchup material editor retain full resolution.
11) a way to ensure certain layers are not affected by smoothing (eg if i have property lines shown on a surface, i want to smooth the surface but not affect the property lines)
12) soft shadows
13) A layer manager function with referencing so that I can 'attach' or 'reference' the drawings of others (eg a topographical survey).
14) Sketchup models have no titleblock in which to edit properties such as "issued" dates, who last edited the model, when it was saved, what status the design is (preliminary, draft, final, etc) or version control (other than the file name). This could be added quite easily, I'm sure.
15) filters or 'tag's for components and materials in the browsers. Eg I could tag something "hi poly" or "manufacturer XYZ" or "Project X" to create collections of my own design. Generally using Collections is quite time consuming and of little value. I find. Lately Im just using A window (microsoft OS) as a way to browse for & load components into a model. The search box for components uses the 3D warehouse (and takes forever) - why can't I search within my local component library? The details showing for each component only include "Author" and "Description" which are usually fairly useless in a pro workflows. What about IFC Classifications or Tags? What about size, weight, etc? Custom fields would make sense (eg a folder of timber components would have their dimensions and grade as the key bits of distinguishing info.
17) Welding edges of contours and curves...pretty basic but this is keeping Sketchup from being used for drafting, which is a real shame.
18) adding labels to contours , labeling each selected face with it's area, labeling selected lines with dimensions, making all text labels glued so they float around like crazy, more tools for adjusting their size, etc, making sure m2 symbols are mapped properly to PDFs and include superscript 2 instead of m ' t
19) make it possible to map a shortcut key for "hide rest of models" and "unhide rest of model"
20) Actually, I could go on, and on, and on...but I'll just say that this isn't a general complaint, I genuinely believe that Sketchup could really benefit from these additions. I wont mention the dozens of extensions that are also necessary to do anything useful in the professional space - we just have to spend (literally) years working through 1000s of possible extensions and forum posts to figure out a set that works for us - it's a huge time commitment.
Sketchup is amazingly simple to use as a newbie and an amateur user but can be incredibly slow to get 'sorted' as a pro user who expects CAD-like workflow tools for Architecture, landscape design, survey, engineering, etc. It's taken me 15 years to get to this point (even approaching programmers to make me custom extensions where necessary).
