Wall line weights


Ken

Question

I wish walls (actually any hybrid objects shown in multiple views) could have a SEPARATE line weight attribute when they're not in top/plan view. The non top/plan view line weight can be as easy and simple as the lightest available lines in the drawing ? it doesn't matter. Those views are usually rendered anyway. Let user define line weight ONLY for top/plan view. This would globally eliminate the odd heavy wall edges:

What is needed are separate attributes for 3D views and section views.

- In 3D Views we need relatively light line weights and solid fill colours so derived elevations and other 3D views appear as they are wanted.

- In Section Views (Top/Plan and Sections) we need thicker pen back lining so cut elements read as being in section in drawings and fills that indicate the material being cut. It can also be argued that it should be possible to have different material section indications for Top/Plan and Sections.

At the moment you can fudge the fill by first selecting a fill colour for a class and then using a hatch for the section indication. This solution has limitations so is not the ideal solution.

The bigger problem though, as this thread identifies, is that if you use a heavy line weight to get the correct weighting in Top/Plan View this does not provide a satisfactory result in model derived elevations. To get the latter correct you need to compromise the Top/Plan View.

NNA can so easily implement this:

  • User defined line weight for Top/Plan view
  • User defined alternate line weight for Section view
  • All other 3D views get default thinnest line (0.03mm or 1mil)

The ultimate goal is indeed to get real-time elevation drawings as SLVP without unnecessary 2D editing. I've also wished this before at length in these forums, apparently falling on deaf ears.

Now, to truly tackle the architectural delineation rule of heavier lines closer to viewer in flat building elevations (as well as perspectives), perhaps an exciting novel approach can be introduced as some sort of dynamic depth of view scaling for line weights in viewports. Say this applies only for Hidden Line render. Say it's a new viewport option. Say you go into the VP annotate, lasso-create a few polygons around your building elements side view, select and stack them polygons front to back, then slide some kind of bar to adjust their lineweights going from heavy to thin. And show the visual effects instantly for artistic/visual judgment. How's that for lineweight delineation?

This would still require the basics ? that of NOT showing the heavy top/plan line weight in other views.
