AutoCAD 2D lines changing to 3D automatically

Most common query I get is objects showing up in 3D from a 2D AutoCAD plan. This is realized when it is imported into Trimble SketchUp or other modeling applications. This can be quite an irritant to the user. So here is one of the checks you can do to correct the AutoCAD drawing. The reasons for unnecessary 3D objects created can be many, but I address in this one of them that could be troubling you.

Check the command “THICKNESS”, if this is having any value other than zero, it will result in all lines to take the value in elevation. Hence ensure THICKESS=0. For those lines that already have taken the thickness, go to properties and use quickselect methods to filter such lines and change in properties to zero.

AutoCAD Mobile App – Keep drawings Alive!

AutoCAD Linetype scale variations

AutoCAD Lintetype Scale

AutoCAD Lintetype Scale






Does your Autocad Linetype scale vary in Model space and Layout space?

If your Linetype (eg Hidden type), is looking correct in Model space as seen above in first picture, but is not showing up in the layout space for any viewport scale(second pic), then follow these steps to resolve this issue.

  • Set MSLTSCALE = 1
  • Set PSLTSCALE =0
  • LTSCALE =1(Do not change this)
  • Make sure you give the LTscale values in the properties box for the selected objects with linetype.
  • Go to model space and regenerate.
  • Best practice is to keep the Modelspace scale as 1:1

Doing this setting will retain the Linetype Scale in Layout space viewports irrespective of  any viewport scale given




Turn off and delete constraints in AutoCAD

remove contraint1How to turn off and delete constraints in AutoCAD?

If you want to get rid of  constraints that are appearing in the drawing and they refuse to go away, follow this procedure:

To turn off geometric constraints, on the command line in AutoCAD, enter  CONSTRAINTINFER and set the value to 0 (zero) or enter CONSTRAINTSETTINGS and then in the Geometric tab, uncheck the box for “Infer geometric constraints.”

To delete geometric constraints, select the objects to remove constraints from and then on the command line, enter the DELCON command.

How to get rid of those Overlapping lines/Duplicates in Autocad? -OVERKILL

A drawing file can have overlapping lines for many reasons:

1. Drafting errors leading to overlapping lines

2. A drawing exported from a 3D based application into Autocad

3. Drawings exchanged between consultants who will add their own lines

Whatever is the reason, we want to eliminate one of the lines & retain other, else it will be double printing & give wrong line thickness.

Command ÖVERKILL” is the tool to do this. If you din’t know this command, you would be using the tedious method of finding & deleting these overlapped lines.

Select the objects with overlapped lines, set the options to delete the duplicate objects & check the dwg.


Autocad How To Change Linetype Scale

LTS is the command to change the Autocad Linetype Scale globally. If we change this value, all Linetypes in the drawing gets updated together.

Autocad How To Change Linetype Scale on only one object and keep other Linetypes in same scale?

* Just select the object to which you want to change the Linetype scale

* Go to its properties(Cntrl +1), select the Linetype Scale and change the value…This will change the scale only for the selected objects & other Linetypes will remain same.


Autocad Plot Scale


Autocad Plot scale : Here’s another Autocad Tip related to Autocad Plot Scale that’s most important to understand because that’s where most of them get confused with when plotting the drawing.

A common grouse I hear from students ..the plot preview is too small for the sheet size, else not fitting into the sheet.

Problem: Plot scale given is correct but drawing not fitting rightly…..

AutoCAD Plot Scales-2 AutoCAD Plot Scales-3

Solution: If the drawing units is in Meters , then while choosing plot scales with respect to the Drawing sheet sizes, here’s the what you need to do :

Divide the required plot scale by 1000. Eg 1:20 is entered as1mm is to 0.02 units.

AutoCAD Plot Scales-1


When Drawing is In Millimeters, the plot scales are very clear, Eg. I want to plot in 1:50 scale, hence in plot dialog box I enter 1mm=50 units as shown

Get away with the Educational Stamp in plot

This post is for my Students in SOA, MSRIT who want to know how to get rid of the Educational Stamp while plotting the drawing.

1. Type in command DXFOUT, to export the existing dwg to .DXF format. Close the file.

2. Use Open command to open the saved .DXF file , under files of type, choose Dxf to browse the .dxf files only.

3. Save the above .dxf file, it will save it as .dwg that does not have the plot stamp anymore.

AutoCAD Docked Windows-undock or float it…

The Layer Dialog Box got stuck to the Left side of the AutoCAD screen & refuses to move or float , no right click option available to switch off ‘allow docking’. The layer properties are not seen properly unless scrolled that makes it very uncomfortable to work… Well if you have faced such situations before, here is what you need to do….

On the task bar, next to workspace tool, there is a Lock icon, right click on it … select … All…under that unlocked. This allows the window to float on screen!AutoCAD 2014- Undock windows-1AutoCAD 2014- Undock windows-2

Text Heights in AutoCAD

One of the common doubts a CAD drafter has is to know the Heights of the text to be used for different scales of plotting so that he has the texts readable & presented as required. Many just guess the height visually but most of the offices would have a chart to help them out quickly, here’s a tip for a beginner:

Text size in model space = Text size required in printout x Plot scale

For eg. If you want to keep the Text size to measure 5mm in the printed sheet plotted to a scale of 1:50 or 1=50mm, then in model space; Text size = 5 x 50 = 250mm.

If you are working in Feet & inches file, the procedure is similar.Multiply the inverse of  plot scale by 12″ x height of Text required.

For eg To get a text height of 1/8″ on printed drawing sheet, plotted to a scale of 1/4″=1’0″ 

Text height in Model space = (4″x12″)/8″= 6″,

Hence 6″ is required Text height in model space.
