Unofficial software detected / File too small

TOAST
EN: Unable to detect floor plan because the size is too small or the file is not exported by AutoCAD.
CN: 未检测到户型图,由于户型图尺寸过小或非AutoCAD官方软件导出。

To solve this problem, please:

  • Only AutoCAD files can be uploaded in Coohom. Please do not use other software.
  • Zoom in your floor plan by 10 times in AutoCAD and export.

File too large

The max .dwg and .dxf files are respectively 5MB and 10MB. If your file exceeds the upper limit, please:

  • Option 1
  1. Paste your floor plan to a new AutoCAD file.
  2. Frame select the entire floor plan. Right click and select Clipboard > Copy.
  3. Copy this project to a new CAD file.

In general, this method can greatly reduce the file size.

  • Option 2
    Remove all furniture in your floor plan and only upload the room layout in Coohom.

Unable to detect walls

This error may caused by the location lines in your floor plan. Your original CAD file may like this:

Please remove those location lines and upload again.

Error 99 / Unable to upload

Basically, many possibilities will result in this failure, please find your own solution.

You can try the following six methods:

  • Coohom only supports the default wall mode of AutoCAD (two parallels) currently.

  • The wall thickness Coohom supports is within 50~400mm.

      TOAST
      EN: Unable to load wall thickness. The thickness should be within 50 - 400mm. Please recheck the wall thickness and the unit.
      CN: 无法正确读取墙体厚度,请检查墙体厚度和单位设置后重试。
    
  • Make sure that all rooms are enclosed in your floor plan. The situation in the figure below will make the CAD file fail to upload.

      TOAST
      EN: Try uploading again after confirming the rooms are enclosed. If the problem is not resolved, please contact us or check more errors.
      CN: 请确认墙体完全封闭后,尝试重新上传。若仍未解决问题,请联系客服或查看其他问题。
    
  • Check if the drawing of the window is correct. The following two figures are both correct.

    And make sure that the window is totally embeded into the walls.

  • The value of line coordinate is too large, just like 16340505101.355. This situation will lead to some calculated mistakes.

    To solve this problem, please frame select the floor plan and copy (Ctrl+C) it to a new CAD file in order to decrease the values.
