Tdgdesign Posted October 26 Share Posted October 26 Hi all, I have an important residential project heading into CDs, and the model has become so slow it’s barely workable. Deleting a single window in a 3D view takes about 4 seconds, and undoing it takes another 4. A new blank plan is lighting fast on the same (brand new) machine, so it’s this model specifically. I’ve already sent the plan to Tech Support, and they were like "we dunno". I’ve also spent a full day testing it myself on a copy. Here’s what I’ve ruled out so far: Layers / auto-rebuilds: turning off all layers and all auto-rebuilds makes no difference. Object types: deleting fixtures, furniture, cabinets, millwork, roof planes and so on one type at a time, none makes a big difference on its own. Walls: removing sections of walls, or switching every wall to a simple default wall type, also makes little or no difference. Textures: Vector View (no textures) is no faster. Undo: turning undo off saves only about 0.35 seconds. Graphics card: Chief is running on the RTX 5080 (DirectX 12). CPU usage stays at about 3 cores and the GPU sits mostly idle. It looks like the delay simply grows with the size of the model (about 245,000 surfaces) rather than coming from one bad object. Deleting the whole main floor makes it fast again. I’ll admit not everything in the model is drawn perfectly, but I’d expect professional software to handle a moderately complex custom home like this. I really like working in Chief and I’m close to the finish line, so I’d much rather fix this than export to AutoCAD and forget about Chief I’ve attached the plan, with cabinets removed to fit the upload limit. If anyone can find the source of the lag, I’ll gladly pay for your time. . Thanks in Advance!!

If anyone can find the source of the lag, I’ll gladly pay for your time. youre upload didnt include materials and im not experience the slow down, this points to a material file that has too many pattern lines. you can prove this on your end by ging to 3d/materials/plan materials then merging all materials in one and check on the slowness. also this plan has a ton of model repairs. Attempting to export a 3d file produced a ton of errors, more than ive ever seen attached the export message logMessage Log.txt Link to comment Share on other sites More sharing options...
Tdgdesign Posted October 27 Author Share Posted October 27 (edited) Hi, Thank you for your reply - sorry for my ignorance but what is a model repair? I merged everything and it didn't help at all.... Also, you are running X18 so maybe that accounts for why you are not seeing the slowness?

Tdgdesign Posted October 27 Author Share Posted October 27 Hi Renerabbitt, I just downloaded X18 and it's still running slower. Another question for you: Since our hardware is close, could you tell me exactly what you’re seeing? In a Perspective Full Overview, select one window, press Delete, and roughly how many seconds until it’s done? Then the same for Undo. For me it’s ~3–4 seconds each way in X17, and slightly slower in X18. I am not trying to be a pest, but I am going crazy over here...

Garybills Posted October 27 Share Posted October 27 @Tdgdesign I just tried it in x17 and x18 and had the same speeds about 1 to 2 second. I'm also using a Lenovo Legio Pro 7 Laptop with the RTX 5080. Link to comment Share on other sites More sharing options...

I don't really get lag there either it's only in 3D perspective view if I delete anything... Edited October 27 by Tdgdesign Link to comment Share on other sites More sharing options...

It was 3d overview and all was good But your project managment file is slow 6 seconds to delete a window Link to comment Share on other sites More sharing options...
Renerabbitt Posted October 27 Share Posted October 27 (edited) You have 16 hours ago, Tdgdesign said: Here is a link: https://www.swisstransfer.com/dl/01a17b13-305b-717d-8de8-8a8ad1968d86 I can't thank you enough for looking into this.... you have several material files that are using complex patterns in the pattern panel. I have told chief this many times, that these complex patterns create thousands of vector lines that can slow down certain CPUs. Delete the custom pattern from your stone Also this model has a bunch of substandard modeling practices making the rebuild of roofs and walls more intensive. These aren't causing huge slow downs but minor ones. Also your schedules create slow downs, as every bit of data being sent to them has to rebuild every time you do anything Lastly, avoid having a plan view open and displayed side by side with a 3d view because chief has to reproduce both views for every action. Just keep one open and on display at a time Edited October 27 by Renerabbitt 2 Link to comment Share on other sites More sharing options...
