Sketchup running slow on a powerful pc

BatelRahat · Aug 23, 2016

Hi,

I'm having some lagging with my Sketchup 2016 Pro while working on a 65MB file. My PC is very powerful - Nvidia Quadro 5000M, Intel I7-6950x and 64GB RAM. **Win10 Pro X64**

Can anyone tell me if maybe I need to make some adjustments in the graphics card settings for Sketchup to run better?

BatelRahat,

Sketchup is notorious for running slowly when the file has almost any size over about 20MB. There are a large number of both complaints and solutions to the problem which is not a matter of the system capabilities- the hardware, but rather the way to manipulate objects. The difficulties derive from the way that everything in the model, including a single line has to calculated in dimension, position and attribute: color, texture, group /component. Curved 3D forms are particularly complex to calculate as they may contain hundreds of thousands of polygons, each one of which has to be constantly re-positioned and given color /textures. As you can imagine, shadows are calculation-intensive.

However, it is possible to improve the navigation significantly:

To make Sketchup run faster:

1. Make extensive use of Layers: Put as much as possible onto layers. These can be turned off when working on one portion and the model will move easily and often it's easier to see things. In a building if the outer walls and roof are layers, it's possible to turn those off to work on interiors. If it's a car or aircraft, turn off the engine layer and interiors to work on the body /fuselage. Turn the layers on to check conflicts of changes.

2. Simplify geometry: Choose carefully how many segments to curves and circles. In a project with complex curved walls that were 350m long, the curves were made into 600 segments to have a smooth appearance, but the file was impossibly large and was redrawn to 200 segments and made the project file change from 56MB to 11MB.

3. Run Sketchup in monochrome view without shadows: This in effect temporarily turns off millions of polygons so it's possible to navigate the model much more quickly. You don't see the colors, textures, and transparent are seen as solid, but it will move about easily

4. Wherever possible, create entities as Components and Groups. The reason is that these entities become a unit that can have a shorthand- it takes the component as a unit and only needs additionally to know it's position /orientation. Yesterday, I decided I wanted to use a 3D Warehouse model of a Herman Miller Aeron chair. This model is 2.2MB. As my building model is 143MB, it's necessary to test the file size of everything and as 125 of these chairs were needed, it would be impossible to add 4,400MB to the model. To test, the model was downloaded to a special file, the model selected and right-clicked to make it a component, and it was copied, made a group of 2, that copied and combined with the first 2 unit group to create a group of 4, that group copied to make a group of 8, that group made 16. I then made 8 copies of that group, exploded so I had a single group of 8 X 16 or 124 chairs. But, the files size was not 278.2MB, it was 3.7MB. In that same building, as it is bilaterally symmetrical and has complex curved walls, I could make walls as components and then only mirror them - or in Eketchup parlance "Fip on x Axis". Of course, the other benefit of Components is that if you change one, all of them are changed. I made a mistake on this building as I did not make a particular pair of doors a component and it took almost two hours to add door handles to all those doors.

5. Use the Purge Unused feature: about every other save, first click on the Model Info /Purge Unused button as the number of faces, materials, and so on will drop and the model will be as trimmed of the unnecessary as possible..

6. Do not add textures until the last. Textures slows down Sketchup tremendously because of the polygon count. Add them as late as possible to the model.

7. if the model becomes very large. separate it into block files. In the current project as there are 5 floors, at the time. I make a model with all major portions in one drawing so it's known to fit together, then separate the major blocks into files.

I hope this helps. Sketchup can be wonderful, but when the files become unwieldy, the most frustrating program in the World. I have a good performing 4GHz Xeon E5 system and cant times I can't believe how long I wait.

Cheers,

I must have missed your answer, I'm sorry.

Thank you so much for your well written answer!!
