Scaling in Layout - quickest way

I imported a dwg file from a collogue (not SketchUp origin) to Layout, which appears to come in a wrong scale. 1:64 which is not even the right scale. I there a quick way to rescale this?

I manually removed scale and sized it to 1:5. Is there a wat to set this to become scaled drawing?

Many thanks in advance

Later edit:
The drawing was in the wrong scale when it was imported. I used ArchiCad to re-scale , it has a “rescale” tool to do this graphically - similar to the measuring tool …This seem the easier solution…

Still…I wonder if there would be the was to covert existing linework into scaled drawing in LO - until we get the FEATURE introduced in 2025 :slight_smile: (wishful thinking this is…)

What do you need to do that setting it to a scaled drawing would be helpful?

I always bring DWGs into SKP, but I use them as a base for modeling… which might not be useful to you.

Did you select the correct import unit (the one used when creating the DWG) when importing?

Yes. That’s what I would like to do.

I know how to start a scaled drawing on Layout, but I am not sure how to convert an existing one to scaled…and the existing drawing have many sub groups given that it was imported form another software (I think VW).

Cheers,

I don’t know or can change how the drawing was saved.

Although, I could set it to the right scale it in ArchiCAD I suppose and then bring it in to Layout…

But as a test, I would like to know if it would be possible to the same in layout. A “measuring tape” tool in Layout would be nice…In face all tool should work similarly in layout to SketchUp…(mirror)

@Anssi is not suggesting changing the units in the program it was created in, rather setting the import units in the import options in Layout to match whatever units the file was created in.

Bring it into SKP then, scale it, setup a top view scene, then send it to LO and set the scale like you would normally on the SKP model tab. You could then render it in vector and explode it if you wanted to edit / control it more.

I’m not sure if you can copy / paste into a scaled drawing in LO, you might be able to give that a try.

This is one solution. Thank you.

I am wondering if there is something you can do inside Layout to do this…

What is your goal with this file in LO? As a backdrop? Or to edit the drawing accurately?

I have calculated the scale factor based on lines in imported PDFs or DWGs. You would need to know the proper dimension of a line or feature in the imported material. You could then start a scale drawing, draw a line at the proper dimension to what you need, then figure out the PAPER space scale factor between the paper measurement of what you drew and the matching line in the imported materials. Then you can use the scale tool to adjust accordingly.

Double check by overlaying the two lines.

You can then dimension the DWG by turning the dimension style to the proper scale manually.

But, you might then be able to edit the DWG group, select all, copy, double click your scale drawing line, and paste.

Or, maybe bring it into SKP, scale it properly. Go to top view parallel, select the geometry you want, switch to LayOut, paste, set the scale?

So I just tested this (never done this in LO):

File>Insert
Picked the model units…
Came in at a random scale, used Make Scale Drawing to change the scale.
Checked one of the dimensions…

I had to add some additional information (linework/image and dimensions) to the original drawing.

I did exactly what you were describing Mike, the problem arise, when I wanted add them dims. The lines were in scale, but as they won’t scale drawing I needed to figure out from previous dims, what would the new element measure. (I it was a simple drawing, a few lines, I could have added it as a LO scale drawing, but it wasn’t and they were partly exiting drawing from another source…)

So I ended up re-scaling in ArchCAD and bring it in again - now in the right scale. So I could easily dimension and add to the drawing.

I just rallied that you can actually add scale to a bunch of line already drawn…The reason I couldn’t do it earlier was that they were in different types of groups, so this option didn’t worked earlier, but no I realized it does work if the grouped are ungrouped.

Thank you for your comments.

Yes. This is what I did, but as the original drawing wasn’t in scale, the imported file wasn’t either.

But now, I re-scaled it in ArchiCAD and I brought it in an I wonder while the scale would come in as 1:101.523, instead of 1:100 ? It didn’t bother me, as the dims I needed corresponded with the original file. I am just wondering…

Just change it with the Make scale drawing pallet like it did in my video. My example also comes in strange but I change it.
