How to join and make faces

Imported dwg file in sketchup for floor plan, why all the lines broken, is there anyway or extension that can make faces with auto joining the edges. With the huge plan its time to build the face connecting the edges. Thanks

dwg importer imports lines. not faces.

you can re-draw some of the lines ant it’ll recreate the faces.
or you can use a free plugin like Eneroth’s face creator. or Alessandro’s Faceup.

here is a quick start with faceup.

import your dwg, either explode it or enter it.
optional, delete the stuff you don’t want, there is always stuff you don’t want.
then select all, right click, and make faces / extrude them. subcomponents (blocks) won’t be affected, only lines.
from there, each face that could be made becomes a 3d group. you can use solid tools to merge them, and add missing bits.

If the DWG has faces, the importer imports them.

true, but fills / hatches are not perceived as faces though.

I have yet to import a 2d dwg file that will come with its fills converted to faces.
on the other hand, I’ve imported 3ddwg that came as 3d faces / volumes.


you need to clean your file first. looks like your doors contain several width.
you can also remove the furniture, you want walls, not symbols

if faces don’t make themselves, it’s because… the dwg has tiny errors like this.

remove all the furniture objects but still some walls not created

Find the gaps and close them.

aaha how u did it can u explain me little in details plz

As @ateliernab pointed out, find the gaps and use the pencil to close them.

any plugin auto find and fill the gaps

how does the software know it’s a gap to fill and not an actual gap to keep ? there are tools that can point to you where 2 lines almost touch but don’t.
but the software can’t guess what should be or not be. it only provides the data as is

anyway to find the gaps?

@ateliernab answered your question already.

You’ll have to look for them.

What version of sketchup are you using? Edge tools is a plugin that can help you to find and close gaps automatically but you need to be using the desktop version of sketchup.

I only had to draw about 4 edges to make it work, it is worth doing it manually to understand where the faults lie. CAD files often have gaps and if you are going to try to use them you should work to understand the issues rather than expecting a plugin to do it for you. But I guess that is an old mans idea of life experience.
