Slab Editing

[Anonymous]

After 20 years of using AutoCAD I am new to Archicad. Please bear with me as I ask what must be very basic questions to some of you.

I purchased the educational version of ArchiCAD 9 a couple of years back. I purchased Virtual Tutor 9 at the same time. I have spent limited time learning ArchiCAD 9 with the help of the tutor. It was just enough to know I wanted to try the full program.

I have recently purchased the full license. I have version 11 and have recently received version 12. I have ordered the tutor for 11 but it has not come yet.

At the moment I am using the Virtual Tutor with ArchiCAD 9 to learn the basics. I will switch to the 11 tutor when it arrives.


Here is my first question:

In the editing slabs section of the tutor there is an exercise to modify a boomerang shape to a Swiss Cross. The exercise shows how to select the slab and then activate the edit tools by left clicking on the slab. It shows how to add a node and then to align the new node at a relative distance from an existing slab node.

The exercise says to click the add-a-node function, then to move the cursor over an existing node until the cursor pen turns black. The tutor then shows how to type in “X” (or “Y”) and a specified distance in order to align the new node at a 90 degree angle, and at the specified distance, from the existing node.

I select the slab, I left click on a slab segment and the edit function box appears. I make sure that the add-a-node function is selected. I then move the cursor over an exiting node, type “X”, and then type -20 to align the new node at negative 20 units to the left of the original node. The new node aligns horizontally but not at 20 units.

I have done this procedure in both the X and Y coordinate directions. I always get a new node that aligns at 90 degrees to the original node but not at the X or Y distances I specify.

I also tried this exercise in ArchiCAD 11 just to see if I had accidentally messed with some of the default settings in 9. I got the same results.

What am I missing here?

Upon reflection, I regret the PEBCAK jab.
It was prompted by this absurdity:

Implying a massive software problem no one else noticed.

Please accept my apology.

David, you may want to change your signature message to "You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) as well as whether you work in metric or imperial units for more accurate help in this forum.

Stuart:

I think the Location should cover that. Is there any other place than the US still using this antiquated system? ; )

Most private jobs in Canada still use imperial dimensions for building even though we have metric time. Lot of your dual-dimensioning here.

Our wood is mainly for US export, so our mills make 4x8 plywood at 1219x2438 and a 2x4 is 38x89. With truths like that, a rational builder stays with feet and inches.

It was a great delight to recently visit a lumberyard in New Zealand and hold a 50x100 stud. Real wood with a non-weasel dimension, eh?

except it was probably 45x90 in reality

I see North American users here quoting metric units too. Is it going to catch on?

Puerto Rico is more confused;
gas sold in liters (metric) while cars use gallons and MPG
distance markers in Km, highway signs in Miles
electricity sold in metric Kw, water in gallons
land sold in "cuerdas" which is almost but not quite the same as an acre
siteplans in meters, architecture in feet inches

One of the biggest demo items for AC (and SketchUp) is preference switching from ft in to meters without scaling:D
