Scaling an imported drawing?

Scaling an imported drawing?

Scaling an imported drawing?

(OP)
Hello all

Im pretty new to all this and am trying to modify an old DWG file, the problem i have is that when i imported the file the scale is wrong (ie a known measurement of say 10 is showing up as 55) i can not seem to change the scale of the old file. In the past on CAd viewers i have used i just highlight a know measurement and input the known dimention and it automatically sets the scale.
Is that the same with draftsight? if so could someone kindly point me in the direction of where to do it as i cant seem to work it out

Cheers

Scaling Entities

Use the Scale command to enlarge or reduce entities while keeping proportions the same.

To scale entities:

Click Modify > Scale (or type Scale).
In the graphics area, select entities to scale.
Press Enter.
Enter the base point.

The base point, if part of the specified entities, holds its original position during scaling, while all other points move by the same relative values in the direction of the X-, Y-, and optional Z-axis. For the base point, you can instead select a point not on an existing entity. In this case, the distance from the base point to all other points making up the entity change by the same scale factor.
Enter the scale factor or specify the Reference option to enter a reference length and a new length. Optionally, specify the Points option to represent the reference length as two points.

A scaling factor larger than 1 enlarges the entities by this factor. A scaling factor between 0 and 1 reduces the entities by this factor. For instance, the factor 3 enlarges the selected entities three times, while the factor 0.25 reduces the entities to a quarter of their original size.

Use Reference to specify an exact change in the lengths of entities. For example, to enlarge an entity with a side length of 3.45 drawing units up to 3.54, you have to calculate the scaling factor. With Reference, however, you specify the reference length (3.45) and the new length (3.54).

Thanks for your promt reply CBL, i did check the help file and there is some helpful utube tutorials up as well but im a bit green on the terminoligy so bear with me.

I think this maybe a problem with my original DWG file,so maybe i should expand my motives slightly. I have a DWG file of our site and i am trying to use this program to refit my workshop,use it to place my plant in a manner that will best suit the enviroment and the work flow.

The DWG  of the site I have is multi layered (85) plan and my work shop is but a (allas far to) small part of it. The plan includes most of our workshop equipment but they are all part of one layer and they dont seem to be entities in them selves so i cant select them or any of there dimensions, also the building gurders which i would of used as a reference point all seem to be one layer so i can only select the whole building rather than one measured point.
The reason i want these measurements is so i can redraw the equipment accurately (as there not accurate on the original) and place them on the workshop part of the plan

sooooo (stay with me here) would i be better of just redrawing the workshop to scale (its a real funny shaped part of the building) and adding the machines as seperate entities?

or am i doing something wrong and i should be able to scale the original drawing??

sorry for the long post and thanks in advance for any help

RE: Scaling an imported drawing?

So you only need to scale or re-size a small portion of the DWG?

Maybe try creating a block of the elements, and then scaling the block?

RE: Scaling an imported drawing?

I think, this depends on the template (in mm or cm???) if this doesn't fit there will be scaling errors
