Adding Linear Dimensions to Exterior and Interior Features of the Building Plan in AutoCAD

Continuing Dimensioning: Focusing on Bump Outs, Windows, Doors, and Interior Walls in AutoCAD

Continue adding dimensions on the exterior and interior of a building model in architectural design. This article will guide you through each step of this process, from marking dimensions on major bump outs, walls, windows, to specific architectural elements like a fireplace or a garage.

Key Insights

  • The process commences with marking dimensions on major bump outs, before focusing on the interior walls. Dimensions are marked with a linear marker, starting from a selected point to the inside of a wall, then continuing to the inside of storage closets and corners of the building.
  • Windows also need to be dimensioned, starting from the inside corner of the wall to the outside corner of the window, and continuing to the inside corner of another wall. Exterior elements are dimensioned using midpoint values.
  • Specific architectural elements like doors and fireplaces have unique dimensioning instructions. For instance, a door is dimensioned using the three-inch jam typical, and a fireplace is marked with a linear dimension. The process includes dimensioning across various architectural elements and saving the changes.

Let's continue the dimensions on the exterior of our building. I'll zoom in up here and go dim linear.

This is the major bump outs line, so I'll go here to here onto that top magenta line right below my 55 foot 9 inch dimension. Then I'll go continue, again choosing the major bump outs first. Here and here.

Enter to say I'm done. Now we can focus on the interior walls. Linear from this point to the inside of this wall.

Continue to the inside of the storage closet and then to the corner of the building. And then one more which goes to the right side of this wall and then finally here. Enter to say I'm done.

And then this window up here needs dimensioned. We'll go linear, inside corner of the wall, outside corner of the window. And then we'll do a continue on the window and to the inside corner of this wall.

Enter to say that I'm done. Escape, escape, escape. Next, we can see that these were dimensioned using those midpoint values and they were dimensioned on the inside of the building but these are exterior elements.

So I'm going to go to my linear dimension. Choose here and then grab the midpoint of this window. Drag it out and click.

Then I'll do a continue to the shift right click mid between two points of this endpoint and this endpoint. Then I'll choose the midpoint here. Enter to say I'm done.

Escape, escape, escape. Finally, let's dimension some of the geometry over here. This door is dimensioned using the three-inch jam typical.

And we're going to do a linear dimension for the fireplace. Here to here and continue across to here. Enter to say I'm done.

And then this window is also three-inch jam typical. We'll go linear on the window and bring it out to there. Zoom extents, control s to save.

Now let's do this side here. I'm going to go to the bottom. This is the major bump outs of the building portion.

Linear dimension on the garage. Then continue. This one continues all the way up to the top here.

Escape, escape, escape. Now I'll do linear and this one focuses on the big windows. So this is here to here.

Continue across the window down to this window and down to this window. Enter to say I'm done. Escape, escape, escape.

Zoom extents and control s to save. All right, we can continue dimensioning our doors, windows, and interior walls in the next video. I'll see you there.
